Severe Service Requirements

Posted on July 16, 2010 by Jim Nelson

A lot of our viewers have asked whether or not they should use their severe service maintenance schedule, which is listed in their car owners’ manual. It can be confusing. Let’s clear the air on this subject. Cricket Killingsworth is from QMI/Heartland, a manufacturer of automotive products and fluids. She’s been in the automotive business for 20 years and is a speaker, a trainer, and a writer. Cricket says there’s so much confusion on this topic because, “Most owners’ manuals actually have two maintenance schedules. Sometimes these are called ‘regular service’ and ‘severe service’. Sometimes they’re simply called Schedule 1 and Schedule 2. A severe service schedule recommends that things like an oil change, air filter replacement, and transmission service be done more often: either in fewer miles or in less time.

Manufacturers create these specific schedules for each vehicle they make. So there isn’t one generic schedule that applies to all cars. In addition to your owners’ manual, Pewaukee automotive repair centers subscribe to information services that provide the maintenance schedules for every vehicle – so they can help you know when to take care of needed services. Below is a typical definition for severe service.

Most trips are less than four miles
Most trips are less than ten miles and outside temperatures are below freezing
You drive in very hot weather
The engine is at low speed most of the time (not on the highway)
Stop and go driving
You operate your vehicle in dusty or muddy conditions
You tow a trailer, regularly carry heavy loads or carry a car-top carrier

It’s common sense: Just a few minutes at freeway speeds allows the moisture in the oil to evaporate. Very short trips, or trips of less than ten miles when it’s very cold, don’t allow the engine to heat up enough to get rid of the water. And water in the oil leads to damaging sludge. Also, towing and heavy loads raise operating temperatures and cause fluids to breakdown more quickly. Dusty and muddy driving means that more dirt will get past the air filter to contaminate the fuel system and engine oil.

The bottom line is that you need to decide for yourself if the regular or severe service schedule is right for you, based on your driving. Look at your owners’ manual, or talk with your Nelsons Automotive of Pewaukee service advisor who can help you know which schedule to follow. Nelsons Automotive of Pewaukee is located at N49W22900 Commerce Center Dr, Pewaukee WI.,

Here is what a fleet manager said recently: “Since city miles are generally tougher on vehicles than highway miles, we use the manufacturer’s severe service schedule as the basis for our preventative maintenance program. We massage those schedules over time, increasing or decreasing the service intervals so that they make the most sense. There is a little bit of art to go along with the science.

Make an honest evaluation of your driving habits. Unless you do mostly WI highway driving in moderate weather, you’ll likely have a fairly good amount of severe service mixed in. Some people just want to play it safe and follow the severe service recommendations, rather than analyzing how they drive each month.

Suspension Service

Posted on July 16, 2010 by Jim Nelson

When you hear the word ‘suspension‘, you may think back to those energetic days of grade school. Well, your car’s suspension is actually a good thing because it keeps your car up off the road and helps provide a comfy ride. It needs to keep your wheels firmly planted over bumps and through curves. Your suspension system has many parts. If you look under your car, it’s basically everything that connects your wheels to the car’s frame. These are heavy duty parts that do a lot of work. They need to be inspected for damage and excessive wear at least once a year. A good time for this is when you get your annual alignment service.

Here are some warning signs that your suspension may have problems:

the car pulls to one side;

it wanders;

the steering is erratic;

you see uneven tire wear;

you experience a poor ride or handling;

you see oil leaking from shocks

. . . you get the picture. You just don’t feel in control when you’re driving.

Some suspension parts just wear out with use. Shocks and struts eventually lose their ability to control your ride. Wheel bearings need to be repacked every couple of years. And some suspension pieces need to be lubricated when you get your oil changed. Your service advisor can oversee an inspection and tell you what problems you may have.

If you’re in an accident, your suspension can be damaged or knocked out of alignment. Even a minor accident, like hitting a curb around Pewaukee or even a large rock can mess things up. With a minor accident it’s tempting to just get an alignment or wheel balance to correct the problem. But if there’s some damage, a simple alignment won’t actually fix the problem, and you’ll just have to align it again after the repairs are made. So if you have an accident, get your suspension system inspected right away. Suspension problems should be fixed immediately because they can lead to unsafe handling.

One big cause of suspension damage is potholes – those nasty magnets that seem to draw our tires right into them. Here are some tips for avoiding damage from potholes: First, keep your tires at their full air pressure. That gives tires their maximum resiliency and will hopefully keep your wheels or other suspension parts from crunching on a big hole. Next, just pay attention. When you see a hole you can’t miss, slow down before you hit it. Driving at a slower speed will limit the damage, and may keep your drink from spilling. But don’t brake directly over the pothole. That will cause the car’s weight to shift forward and add to the potential damage.

So don’t put off an inspection of your suspension. We promise the principal won’t be involved.

Radiator Service

Posted on July 15, 2010 by Jim Nelson

The coolant system is a vital part of your vehicle. It is also the second most common cause for vehicle failures. Even though coolant system failure is fairly common, it is easy to prevent.

The most recognizable part of the coolant system is the radiator. It is connected to the engine with hoses and is filled with coolant. The coolant draws heat off the engine and then goes into the radiator. Air passes through cooling fins to reduce the temperature of the coolant and then it’s back to the engine again.

There are several ways for the cooling system to fail. Most common is with the coolant itself. Coolant is a mixture of water and antifreeze. The proper mixture keeps the coolant from either boiling away or freezing. Both of which can result in massive engine damage.

Another very important coolant issue that is often overlooked is the age of the coolant itself. antifreeze has additives that protect the coolant system from corrosion. As these additives are depleted over time, they can’t protect the radiator and other parts from rust, scaling and corrosion. Old coolant may still keep your engine cool, but it won’t protect it from corrosion.

If you see a warning message to check the coolant or if the temperature gauge is in the hot zone your cooling system needs to be checked. It’s OK to add water or antifreeze yourself. But you need to be cautious. Remember four things.

First, you never want to open the radiator pressure cap. You could be severely burned.
Second, try to get to a Pewaukee service center such as Nelsons Automotive of Pewaukee immediately if your coolant is low. If that is not possible, follow the directions in your owners manual – it will direct you to only make additions to the coolant overflow bottle.
Third, remember that you need a proper mixture of water and antifreeze. If you make an emergency addition to your cooling system, follow-up with your service center where they can make necessary corrections.
Fourth, not all cars use the same type of antifreeze. You need to check your owners manual to make sure you use the right kind. Mixing antifreeze types or using the wrong kind of antifreeze may void the manufacturers warranty on your cooling system. Again, another reason to rely on your Pewaukee service center to do things right.

Remember, Nelsons Automotive of Pewaukee has the equipment to change your coolant quickly and inexpensively. 262-691-7113

Trip Inspection

Posted on July 15, 2010 by Jim Nelson

North Americans love their cars. And nothing goes with cars better than the road trip. Freedom from daily schedules, new sights and the open road – it’s great! But there’s nothing like car trouble to bring the fun to a grinding halt.

Now you can’t always avoid problems, but you can take steps to reduce the probability of getting sidelined on your trip. The first step is to look at your trip plan from your vehicle’s perspective. What kind of roads will you be traveling – winding byways or super-highways? Mountains or plains? What weather conditions are you likely to encounter? How many miles will you travel? How much weight will you be hauling – passengers and luggage? Lugging a trailer or roof top carrier? Will it be dusty?

Armed with the answers to these questions, you can start a trip inspection to help you prepare your Pewaukee vehicle for your big adventure. A lot of our Pewaukee customers prefer to go through this exercise with an automotive service advisor at Nelsons Automotive of Pewaukee to get their input and make sure they haven’t left anything out.

A great place to start is with the tires. Inspect them for tread wear and proper inflation. Is it time to rotate your tires? Replace them? Are they up to the job – you wouldn’t want to drive regular highway tires on a muddy off-road adventure.

Shocks and struts play a major role in both driving comfort and safety. If they need to be replaced, you’ll really be glad you did once you hit the road. Is it time for a wheel alignment? Fighting a car that’s pulling to one side all day can be tiring and dangerous.

And don’t forget your brakes. Any strange noises, grabbing, soft or hard peddle feel? If there is any doubt, get a brake inspection before you leave.

Moving under the hood, have your belts and hoses inspected. If something is excessively worn or near failure, the stress of a long road trip might just be the straw that breaks the camel’s back.

Your engine air filter will be important. For every gallon of gas you burn, your car will filter and use 12,000 gallons of air. If the filter needs to be changed, you’ll notice the fuel savings on your trip.

How close are you to your next oil change? Will you be able to complete your trip before it’s due? If not, just get it taken care of before you go so that you don’t need to interrupt your trip. In fact, a full service oil change is a great idea because they will top off all your fluids and check to see if any other maintenance items are due, such as transmission or cooling system service.

Do you notice any unusual odors in your vehicle? If so, it could as harmless as a dirty cabin air filter. But if it’s an exhaust leak it could be fatal on a long trip. Of course you’ll want to be comfortable, so get an air conditioning service if you aren’t getting the cold air you used to.

Are you wiper blades still working well? If not, that is quick and inexpensive to fix. Headlamps are often overlooked when planning for a trip. If you haven’t changed the bulb in six months or so, replacement bulbs will really light up the night on your trip.

All the items mentioned are part of any good vehicle maintenance plan. These are things that you want to take care of anyway, but they all come into focus as you plan for your trip.

They will always save you money in the long run and may prevent inconvenient delays on your trip. After all, you wouldn’t want to miss the world’s largest ball of string, would you?

Exhaust Service

Posted on July 14, 2010 by Jim Nelson

Whenever we talk about exhaust service, most people normally think about exhaust pipes and mufflers. Well, actually, exhaust service is a lot more comprehensive these days. For example, catalytic converters were mandated in 1976 and on-board emission control computers in 1990. Governmental emissions requirements have forced manufacturers to come up with much more sophisticated ways to comply with environmental regulations.

Exhaust service has really become exhaust and emissions service. High-tech computer controlled emissions devices are now a big part of exhaust service. Because it is so sophisticated, your vehicle manufacturer recommends you have your emission system checked out by a qualified Pewaukee exhaust technician regularly to make sure everything is working right – usually every 6 months or 10,000 miles/16,000 kilometers.

If your Check Engine light comes on, especially if it’s flashing, get your car looked at right away. Technicians at Nelsons Automotive of Pewaukee handle emission problems everyday. You might have exhaust or emissions trouble if your car is difficult to start, runs rough, is noisy or smoking. Call Nelsons Automotive of Pewaukee at 262-691-7113 to schedule an appointment if you experience these problems.

Let’s review the exhaust system. We will start from the top and start with the exhaust manifold. That is the part that attaches to the engine and collects the exhaust from the cylinders and directs it into the exhaust pipe. Exhaust gaskets help seal the connection with the manifold and various other joints along the way. If the manifold is cracked or loose, or a gasket is leaking, dangerous gases could escape into the passenger compartment, where you ride. Carbon monoxide can be deadly, so it is important that your exhaust system doesn’t leak. The exhaust pipes connect the various components. They can rust or be damaged by a rock, so they need to be inspected periodically.

Next is the catalytic converter. This part looks like a muffler. It changes chemicals that are dangerous to your health and the environment into harmless carbon dioxide and water. It doesn’t require any maintenance itself. But eventually they wear out. You will find this out when your car fails an emissions inspection.

Now the muffler. Its main job is to quiet engine noises. Mufflers work by either absorbing or baffling sound. And you can actually customize your car’s sound with different mufflers – anything from whisper quiet to bad-boy rumbley. Rusted or road-damaged mufflers can leak and need to be replaced right away.

The exhaust system is attached to the car by a series of hangers and clamps. These fasteners hold the system in place. When hangers come loose or break, hot exhaust components can touch and melt wires, hoses and lines.

Finally, we end at the tailpipe. This is the final outlet for the exhaust. These can be plain-Jane or pretty flashy. Also, the oxygen sensors monitor the oxygen content of the exhaust so the engine control computer can adjust the fuel-to-air mix to keep the car running right.

Exhaust and emissions service covers plain old pipes and high-tech computers. It impacts everything from life and death safety due to exhaust leaks, to fine-tuning the sound of your ride.

Power Steering Service

Posted on July 14, 2010 by Jim Nelson

For most of us, it is hard to remember life without power steering – cranking those great big steering wheels? It was a pretty good workout. Now power steering is standard. The heart of any power steering system is its pump. The pump pressurizes the power steering fluid that provides assist for steering. Most pumps are driven by a belt that is run by the engine – a few are electrically powered. A high-pressure hose passes fluid from the pump to the steering gear. A low pressure hose returns the fluid back to the pump.

These hoses can develop leaks, so it is a good idea to inspect them at every oil change. Low fluid can damage the power steering pump. That is why fluid level is on the checklist for a full-service oil change. The fluid needs to be compatible with the hoses and seals, so check your owners’ manual for the right type – or just ask your service technician.

The fluid cleans, cools and lubricates the power steering system. It breaks down as the years go by and collects unwanted moisture, so it needs to be replaced from time to time. Many manufacturers specify power steering service intervals. Unfortunately, this important service is sometimes left off the maintenance schedule. So, when in doubt, every 25,000 miles/40,000 km or two years is a good fallback. Your Pewaukee or Sussex service center will use a detergent to clean the system, flush out the old fluid and replace it with the good stuff.

Here are some warning signs of trouble with your power steering: It’s harder to turn the wheel, there’s erratic power assist, you hear loud whining coming from the pump (which may be difficult to hear over the loud whining coming from the backseat), you have to top-off the fluid frequently, or you hear squealing belts. Remember to never hold the steering wheel to the far right or left for more than a few seconds at a time. That will wear out your pump real fast.

Other steering components can be bent or damaged from wear or hard knocks. Ball-joint, idler-arm, steering-gear, steering-knuckle and tie rod to name a few. Warning signs here are steering play, wandering, uneven tire wear, and off-center steering wheel. An annual alignment check at Nelsons Automotive of Pewaukee in Pewaukee will reveal bent or damaged steering components.

Most SUV’s, pick-ups and rear-wheel-drive cars need regular front-wheel-bearing service.

The bearings should be cleaned and inspected. If they are excessively worn, they need to be replaced. The bearings are then repacked in clean grease. It’s also recommend the wheel-seal be replaced when the bearings are serviced. Like everything else, check your owners’ manual maintenance schedule. It’s usually required around every two years or 40,000 miles/64,000 km. If you drive through water, the bearings will need service more often.

Braking News: Keep Your Stopping Power

Posted on July 13, 2010 by Jim Nelson

Richard Petty once told AutoNetTV, “You’ve gotta have good brakes. If you’ve got good brakes you can keep yourself out of a lotta trouble.”

That’s why a regular brake inspection is on every Pewaukee car’s maintenance schedule. An inspection at Nelsons Automotive of Pewaukee will check your brake system and let you know if there are any problems.

Of course, if you’re having trouble with your brakes, get your car into Nelsons Automotive of Pewaukee right away. Here are some symptoms to watch for:

Low or spongy brake pedal

Hard brake pedal

A brake warning light that stays on

Constantly squealing or grinding brakes

Vibrations or clunking sounds when you apply your brakes

If you are experiencing any of these, it’s time to get your brakes checked.

There are two types of brakes: disk and drum. Disk brakes have a rotor that’s attached to the axle. Calipers straddle the rotor, kind of like the brakes on a bicycle.

Drum brakes are more common on back wheels. Both types have pads or shoes that press against the brakes and slow the vehicle. Brake pads and shoes are made out of very tough material to withstand the heat and force generated when stopping your car. Eventually, they wear out with use, and become too thin and need to be replaced.

If the brake pads wear away completely, you can damage the rotors. The calipers can grind grooves in the rotor. Then the rotor must either be resurfaced or replaced. That’s not only expensive, but also dangerous because your vehicle won’t stop as quickly. Sometimes rotors warp or crack and must be replaced.

Brake service will also include a check of your brake fluid. When the brakes are applied, the pressure in the fluid actives the brake pads or shoes. Not enough fluid means not enough pressure to brake properly. Also, water builds up in the brake fluid over time, which leads to corrosion, leaks and brake damage, and with hard use, the brakes could severely fade or even fail. You should change the brake fluid when your manufacturer recommends to avoid these problems.

There are different grades of brake pads; good, better and best. Higher grades cost more, but give better braking performance and smoother operation. It’s OK to upgrade your brake pads. But, never use a grade that’s lower than what the manufacturer recommends.

So, be sure to properly maintain your brakes, because it’s a lot cheaper than paying the body shop after an accident.

Come in to Nelsons Automotive of Pewaukee for an brake inspection before damage occurs. You can call ahead for an appointment by calling 262-691-7113.

Fuel Injectors

Posted on July 13, 2010 by Jim Nelson

The last new car sold with a carburetor in North America rolled out of the dealership in 1990. Since then, all new vehicles have had fuel injectors. In very simple terms, a fuel injector is a valve that squirts fuel into your engine. Your engine control computer tells the fuel injector how much gas to deliver as well as the precise time it should be delivered. Of course this happens thousands of times a minute. Fuel injection is a much more precise way of delivering fuel than carburetors. That translates into better fuel economy and power. Virtually all fuel injectors for gas engines are known as port fuel injectors because they deliver the fuel to a port just outside the cylinder. Port fuel injectors operate at about 40 to 80 pounds per square inch of pressure.

A few auto makers have introduced gas direct injection systems on some engines recently. These systems inject the gas directly into the cylinders under very high pressure – hundreds of times the pressure of port injection systems. Although more complicated, direct injection technology promises greater power with improved fuel economy, so we can expect to see more of it in the future.

As you can see, the level of precision required of your fuel injectors is very high. They need to be operating properly in order for your car to run right.

High temperatures under your hood and variations in gas quality cause fuel injectors to become fouled with wax, dirt, and carbon. Injectors can become partially clogged, preventing them from delivering the proper amount of fuel at the correct pressure. The design of each engine requires a specific spray pattern from the fuel injector that might be altered when the injector is dirty. When injectors are dirty, the fuel doesn’t burn as efficiently resulting in poor fuel economy and loss of power. So it is important to keep your fuel injectors clean.

Skilled service technicians at Nelsons Automotive of Pewaukee in Pewaukee can perform a fuel system service for you. (Visit http://www.nelsonsautomotive.com/contact_us.php.) That is a fuel system service – not just fuel injector cleaning. That is because the fuel has a lot of ways to become dirty or contaminated between the gas tank and the fuel injector. A fuel system service starts with a fuel filter replacement. This filter cleans the gas as it leaves the tank. The various parts of the fuel intake system need to be cleaned from time to time to remove harmful gum, deposits and varnish. Finally, the fuel injectors are cleaned so that they operate properly and deliver the right amount of fuel at the right time.

Your Brookfield area service center uses a process for cleaning your fuel system that includes state-of-the-art cleaning chemicals as well as some old fashioned scrubbing. Proper maintenance of your fuel system means that you will spend less on gas, enjoy strong performance and prevent costly repairs down the road.

Air Conditioning Service

Posted on July 12, 2010 by Jim Nelson

Do you hear loud noises under the hood when you turn on your air conditioner? Do you only get cool air sporadically? If so, it is time to get your air conditioner checked. It’s real easy to take your car’s air conditioner for granted. Just push the right buttons and out comes cool, dry, clean air. But your air conditioning system needs attention from time to time to help it keep its cool.

When most people hear the words “air conditioning problems”, it sends a shiver up their spine. That is because the air conditioning system is fairly complex. It has a lot of parts and when it’s broken, it’s expensive to repair.

What things can we do to prevent air conditioning breakdowns?

A common cause of air conditioning failure is leaks. Water and air can leak into the system. The system doesn’t work as well with air in it. And water can cause rust that leads to damage of the A/C components. Also, refrigerant, the stuff that makes the air cold, can leak out, reducing the efficiency of the system, making it work harder to cool the air. Periodically evacuating the air conditioning system and recharging it keeps the proper amount of clean refrigerant in the system so it cools better and lasts longer.

You should also run the air conditioner regularly, even during WI winters, so that it lubricates itself and keeps the seals from drying out, which leads to leaks. Your owner’s manual will have recommendations for how often to service your air conditioner. Of course, if it’s not working right, now is the time to get it checked. Many Waukesha service centers can inspect and test your air conditioning and offer evacuation and recharge services. We recommend Nelsons Automotive of Pewaukee in Pewaukee. See http://www.nelsonsautomotive.com/contact_us.php for address and phone number. A quick inspection can help you avoid having to bring your air conditioner in for major repairs.

New environmental laws have stopped the manufacture of Freon, a refrigerant that was common in cars made before 1993. There is a very limited supply of Freon so the price is very steep. It may not be worth its weight in gold, but it probably is worth its weight in silver. If you have an older vehicle that uses Freon, you may want to consider having it retrofitted to use the new R134-A refrigerant. It will pay for itself in the long run. So, if your AC is just a lot of hot air, take it to a Brookfield automotive service center for an inspection.

Vehicle Warranties

Posted on July 12, 2010 by Jim Nelson

If you own a WI vehicle with a warranty, beware! Many dealers and manufacturers suggest that you need to get your maintenance services at a dealership in order to keep your warranty. That simply isn’t true! You can have your vehicle serviced at your trusted, local service center without affecting your warranty. A federal law, called the Magnuson-Moss Warranty Act, prohibits a manufacturer from voiding your warranty just because you got parts or services from a non-dealer. In fact, a manufacturer can’t require you to use their brand of oil filters, lubricant, or any other part in order to maintain your warranty protection. This protection is true for aftermarket extended warranties purchased on new or used vehicles. This protection also applies to leased vehicles. There are similar laws in Canada as well.

If a manufacturer can prove that the replacement parts or service lead to a vehicle failure, they can void a portion of the warranty. Of course, Nelsons Automotive of Pewaukee uses quality parts and fluids that meet or exceed manufacturers’ specifications. (See http://www.nelsonsautomotive.com/contact_us.php.) A lot of people do not know that service centers subscribe to data services that tell them exactly which parts and fluids meet manufacturers’ specifications. These services are updated constantly so that your Waukesha automotive service center always knows what you need for your car. You can be assured that your vehicle will receive high quality replacement parts that’ll keep you safely on the road.

Proper maintenance is so important to safety. It can also prevent costly repairs and save you money over the long haul. Just because you don’t have to go to a dealer to get your maintenance service performed doesn’t mean that you don’t need to have it done at all. In fact, some protections from your warranty require that scheduled maintenance be performed. If you miss having important work done, you may lose some warranty coverage. Refer to your owners’ manual and vehicle warranty for more details. And keep good records of the work you’ve had done.

The protection you receive under the Magnuson-Moss Warranty Act can save you hundreds of dollars each year. The average hourly labor rate for service is nearly twenty percent lower at independent service centers such as Nelsons Automotive of Pewaukee. We are conveniently located at N49W22900 Commerce Center Dr in Pewaukee. So why go anywhere else?
