Timing Belt

Ever heard the sad tale of a staggering repair bill from a broken timing belt? Bad news. Let’s take a lesson from their woes and remember to think about our timing belt.

First, let’s review what a timing belt does. The top part of the engine, over the cylinders is called the cylinder head. The head contains the valves. There’s at least one valve that lets the fresh air into the cylinder. This air, mixed with fuel, burns to create power. Then another valve or two open to allow the exhaust out of the engine. Each cylinder has 2 to 4 valves – that’s 12 to 24 valves for a V-6, up to 32 values on a V-8. The opening and closing of the valves is done by a camshaft. The timing belt uses the rotation of the engine to drive the camshaft which opens and close the valves. It’s called a timing belt because it has to be adjusted to rotate the camshaft to keep proper time with the engine so that everything’s in sync.

The timing belt is a toothed rubber belt . But some cars use a timing chain or timing gears instead of a belt. Timing chains and gears are much more durable, but manufacturers are using belts more because they are quieter – and cheaper. If you have a small or mid-sized passenger car, crossover or mini-van, chances are you have a timing belt.

Unfortunately, timing belts fail without any warning. That shuts you down right away. A technician can inspect your timing belt and look for cracks and looseness. But getting to the belt to take a look can be almost as much work as changing it on some cars. That’s why manufacturers recommend replacing the belt from time to time. For most vehicles it’s from 60,000 to 90,000 miles or 95,000 to a 145,000 kilometers. If your owners’ manual doesn’t specify an interval ask your service advisor.

One AutoNetTV producer has had two timing belts fail. The first was while he was waiting at a stop light – that repair cost several thousand dollars. The second was while driving on the highway – that one cost more than twice as much. Both had the cars out in the shop for three weeks. His cars had what we call “interference engines”, meaning that the valves and pistons are very close to each other. If the timing belt slips even one notch, the pistons will slam into the open valves. That’s why our friend’s highway failure was so much more expensive – his engine was traveling so fast that the valves were smashed and they chewed up the cylinder head.

A non-interference engine will just shut down if the timing belt breaks. You’re stranded, but the engine doesn’t suffer permanent damage. In both cases, our hapless friend was just a couple oil changes past the recommended interval for changing the timing belt. This is one of those things that you just cannot put off. Now replacing a timing belt is not cheap – but repairs for a broken belt can be many times as much.

Check your owners’ manual right away – especially if you have more than a 60,000 miles or 95,000 kilometers. You may need to get that belt replaced right away. And on many cars, the timing belt drives the water pump. So, it may be a good idea to replace the water pump while you’re at it because 90% of the work required for the new pump is already done with the belt change. Doing both at the same time saves you a lot of money because as they say, “timing’s everything”. Parts, Timing Belt

What happens when your timing belt breaks on your Audi A4

IMG_0872[1]    IMG_0875[1]

This is what your VW / Audi 1.8L looks like after tear down when your water pump and timing belt are not replaced at the correct maintenance intervals. This poor soul bent most of the 20 intake valves and 8 exhaust valves and it all happened in a matter of minuets. When your service center asks if your timing belt was serviced, don’t guess and say yes if you are not sure because we can do an inspection to find out for certain. This beautiful car was religiously serviced by the dealer and the owner believed all the services were up to date. It was a painful repair process but now that its back to perfect running condition and it’s a really nice car again, ready for more German engineered driving fun.

Alternative Fuel Vehicles In Pewaukee WI

Let’s talk about alternative fuel vehicles. In their quest to reduce the use of fossil fuels and harmful exhaust emissions to our Pewaukee environment, automakers will have a number of alternatives for us very soon.

For instance, Flex Fuel vehicles are already available in the Waukesha area. Flex Fuel vehicles can run on gasoline or on E85 fuel. E85 is a mixture of 85 percent ethanol and 15 percent gasoline. The ethanol is made from corn.

The benefits are in using less petroleum and reduced pollution. The drawbacks are that E85 gets lower fuel economy and that when gas prices are low, E85 can be more expensive than straight gasoline.

You should only use E85 if you have a Flex Fuel compatible engine. Flex Fuel vehicles have special seals and gaskets that can stand up to the high alcohol content of E85. Using E85 in a regular engine can lead to gas leaks and fires.

Diesel engines have been around the Waukesha area for a long, long time. Modern diesels are very refined and fuel efficient. Diesel fuel can be made from renewable sources like vegetable oil, too. Diesel fuel from algae and sunlight is reported to be pretty close to being commercially viable.

There are also a number of natural gas vehicles on our Waukesha roads. Gasoline engines are adapted to run on compressed natural gas. It’s less expensive than gasoline and burns very cleanly. You can even refill it with a special pump from your gas line at home.

Natural gas engines don’t make as much power and don’t get as good of mileage, but they cost less per mile to run. The big inconvenience is that the tank that holds the compressed natural gas takes up a lot of room; even your whole trunk! And there may not be places to refuel on a road trip from Waukesha.

Plug-in electric vehicles are now available in our Waukesha area. Battery technology is the limiting factor right now. Electric cars have a limited range and are really best for use close to home. As battery technology advances, electric cars will perform closer and closer to conventional power plants.

That brings us to hybrids. There are a bunch of hybrids on our Waukesha roads, with more to come. Hybrid technology combines internal combustion engines with electric motors.

A mild hybrid has a regular gas or diesel engine that’s assisted by the electric motor. The electric motor can propel the vehicle by itself up to a certain speed under gentle acceleration. There are mild hybrids in full-sized pickups and SUVs. They deliver city fuel economy similar to their highway ratings.

A full hybrid will rely primarily on the electric motor for power. It’ll have a small gas or diesel engine that generates electricity for the batteries.

Another breakthrough technology is hydrogen fuel cells. Fuel cell vehicles use hydrogen to generate electricity. Several global car makers have prototypes on the road. The appeal is that the only thing that comes out of the tail pipe is water vapor. It’ll take some time to build a national infrastructure of hydrogen fueling stations before there’s widespread use.

A quick word about safety around hybrid and electric vehicles. Unlike the battery in your current family car, these carry enough voltage to kill you. Never mess around under the hood or with the batteries or electrical wiring. Your Waukesha service technician at Nelsons Automotive of Pewaukee is trained to safely disable the flow of electricity before performing maintenance or repairs on the vehicle.

Hybrids are really not do-it-yourself vehicles unless you’re specifically trained on hybrid systems.

TPMS: Tire Pressure Monitoring For Your Pewaukee Auto

You may know that all 2008 model year and newer cars, mini-vans and light trucks in Pewaukee come with a tire pressure monitoring system. Many slightly older vehicles around Pewaukee have these systems as well. A tire pressure monitoring system – called TPMS – consists of sensors on each wheel that measure tire pressure.

If tire pressure drops 25 percent below the manufacturer’s recommended pressure, the sensor sends a signal to a monitoring unit that causes a warning to light up on the dashboard. When you see the warning light, you know it’s time to put some air in your tires.

There are many benefits to driving with properly inflated tires around Pewaukee. First is cost savings. Running at the correct air pressure improves fuel economy. Driving on under-inflated tires is like driving through sand – it drags down your fuel economy. You’ll also see longer, more even tread wear so your tires’ll last longer.

Another important benefit of properly inflated tires is increased safety. Under-inflated tires become hotter and that heat can actually lead to tire failure – possibly resulting in an accident. Your car and the tires themselves will just perform better and more safely around Pewaukee with properly inflated tires.

Local Pewaukee consumer groups, law-makers and vehicle manufacturers advocate TPMS systems hoping that they will save lives, property damage and inconvenience. While you can’t put a value on saving a life, we keep in mind that TPMS systems will carry a cost.

The systems themselves are added into the price of the car. The batteries in the sensors will have to be replaced from time to time. Parts will break and need to be replaced. In colder climates around WI, ice and salt are frequent causes of failure.

In addition, there are other behind-the-scenes costs to be aware of. Every time a tire is replaced, repaired, rotated or balanced, the tire technician has to deal with the TPMS system.

Your service center (Nelsons Automotive of Pewaukee) must purchase equipment used to scan and reactivate the TPMS system after every tire service. Because older tire change equipment can damage TPMS sensors, your service center may need to buy expensive, new tire changers.

Since there is no uniformity among manufacturers, technicians need to be trained on several TPMS systems. These behind-the-scenes costs are very real to your service center.

That’s why they are anxious for you to understand the financial impact of TPMS systems. In the past, they’ve been able to quickly and cheaply provide tire services, and then pass the low cost on to you as an expression of their good will. But now even these simple jobs will take much longer.

Sensors will need to be removed and reinstalled. Even a tire rotation will require that the monitor be reprogrammed to the new location of each tire. When a car battery is disconnected, the TPMS system will need to be reprogrammed.

So when you start so see the cost of tire changes, flat repairs and rotations going up, please keep in mind that it’s because of this new safety equipment. Nelsons Automotive of Pewaukee just wants to keep you safely on the road – and we’re committed to do so at a fair price.

It’s important to remember that the TPMS warning only comes on when a tire is severely under-inflated. You’ll still want to check your tire pressure on a regular basis. At every fill-up is best, but you should check pressure at least once a month. Here’s wishing you safe travels.

Keeping Your Pewaukee Air Fresh When Driving With A Clean Cabin Air Filter

What is a cabin air filter? Is it:

A. A filter for your Pewaukee house?
B. A fresh, piney scent?
C. A filter for the passenger compartment of your car?

Clever you, it’s C.

A cabin air filter cleans the outside air before it comes into the passenger compartment. It filters out common Pewaukee air particles like dust, pollen, spores, bacteria, pollutants, exhaust gas, odors and even sparrows.

These high tech filters can block particles larger than 3 microns. By contrast, a grain of sand is about 200 microns.

Not all vehicles in Pewaukee have cabin air filters. They are fairly new on the scene. About forty percent of new vehicles sold in Pewaukee come with cabin air filters, but the number is growing every year.

Cabin air filters can make for a very nice driving environment. Your car can be a haven during our Pewaukee allergy season with very little dust and pollen getting into the cabin. However, the filter eventually gets clogged. When this happens, your heating and air conditioning flow can become restricted. The filter can even get kind of smelly.

Check your owner’s manual for recommended replacement intervals. Often, the owner’s manual forgets about the cabin air filter, so ask your service technician at Nelsons Automotive of Pewaukee for a recommendation. It’s usually every year or 12,000 miles / 19,000 kilometers. Change it sooner if you drive in dusty conditions around the Waukesha area, or if you start to notice an odor from your ventilation system.

So keep your cabin air filter clean. It may not help with your brother-in-law in the backseat, but it will make your driving experience around Pewaukee more enjoyable.

Come by Nelsons Automotive of Pewaukee and we’ll take a look at your cabin air filter for you.

The Importance of maintaining door lock cylinders

Nelsons Automotive of Pewaukee Audi A4 Door Lock Cylinder

When was the last time you used a key to open your door? Lack of use and lack of maintenance is the two main reasons why at Nelsons Automotive Of Pewaukee we find that a large percentage of cars we service have seized door lock cylinders. Now you ask why that is important, when all I need is my remote to get into my car. Try opening your car with that remote when the battery is dead on the car or your key fob, it won’t work. You then reach for the key and come to find the lock cylinder will not move. You now need to make a call to a lock smith to break into your and then have it towed to me to replace the cylinder and key it to match the rest of your locks. An expensed worth avoiding as well as the hassle and inconvenience of it all, don’t you agree? This is why we recommend every 12 months or every 15,000 miles the lock cylinders be lubricated with graphite lubricant to help avoid going through this painful ordeal.

Training Received by Technicians In Pewaukee WI

When your car breaks down in the Pewaukee WI area, or just needs some routine service, it can make you a little nervous. Because your car’s so important to your life, you need to be back on the road as soon as possible. And, with the problem fixed right the first time.

We’ve been checking into some of the training our Pewaukee WI technicians receive, and we’re very impressed. It’s amazing how much knowledge and skill goes into diagnosing and repairing a modern car. So it’s not like when your uncle worked on his hot rod over weekend.

Today there are four cylinder engines that make more power than the V-8’s in luxury cars 20 years ago. A new V-6 Toyota Camry could beat Sonny Crocket’s Ferrari in a race to 60 mph.

Our engines are more and more powerful and at the same time their fuel economy keeps inching up. And they’re so reliable. This is all due to engineering. But the advances come at the price of simplicity. Modern cars are so much more complex from a mechanical standpoint that it makes your head spin.

Then there’s the electronics. Some cars in the local Pewaukee WI area have several networked computers controlling most of the engine functions and many other vehicle functions as well. We take all of this sophistication for granted – but somebody has to fix it when it breaks.

It’s a real challenge for your local Pewaukee WI technicians to keep up. It requires a high level of commitment on the part of the auto technician and the service center as well. In addition to the training, there’s the financial commitment to purchase the diagnostic and repair tools as well.

So where do Pewaukee WI technicians go for training? There’re many sources. It’s usually a combination of formal classroom training, training provided in the service center by parts and equipment manufacturers, on-line courses and home study courses. There are many independent certifications available all the way up to Master Technician.

And AutoNetTV produces monthly training for service centers called The Pro Channel. If you were to watch the Pro Channel segment on re-flashing the engine control computer, you’d be amazed at how much is involved: special software, hardware interfaces and a tremendous amount of knowledge and skill.

Service centers in Pewaukee WI have a lot of other resources available as well. No one can know everything, so service centers like Nelsons Automotive of Pewaukee subscribe to data services, technical libraries and even on-line communities that can help them with they run into a difficult problem.

It’s like those medical diagnosis shows on TV. Here are the symptoms – what’s the diagnosis and treatment. Diagnosis is every bit as much an art as a science. As consumers we want everything to be simple, straight forward and cheap – and sometimes it just isn’t.

So, be more relaxed next time you take your car in. You really should trust your service advisor at Nelsons Automotive of Pewaukee. You’re in good hands. The more you know, the more comfortable you can be with your automotive service decisions. Visit AutoNetTV.com to see more great auto tips videos about many service topics.

Busting Automotive Myths In Pewaukee WI

Myths passed around our Pewaukee WI community start with a grain of evidence and are then built up with a lot of imagination and very elastic logic. And the internet is a breeding ground for automotive myths. Some bloggers recall the SUVs of yesteryear and declare their modern decedents to be virtually maintenance free and that anyone who says otherwise is out to rip you off.

To get the truth about auto myths you hear around the Pewaukee area, come over to Nelsons Automotive of Pewaukee.
You’ll find us at N49W22900 Commerce Center Dr, Pewaukee, WI 53072.
Give us a call at 262-691-7113 to make an appointment for your next auto service.

Let’s examine a couple of the more popular rants and look at the truth behind them.

The first one is that the chassis no longer needs lubrication for suspension, steering and the driveline. They declare that anyone who has charged you for lubrication is a charlatan.

The truth on which this myth is based is that many new cars come from the factory with sealed joints and cannot be greased. However, there are still some grease points on many cars around Pewaukee. A grease fitting may have been installed in conjunction with a repair. And most trucks and truck-based SUVs driving in Pewaukee still require chassis lubrication. This is because they are more heavy duty and proper greasing is still required to keep them going.

Another common rant you’ll hear around Pewaukee is that modern cars don’t need tune-ups. That depends on your definition of a ‘tune-up’, which has changed as technology has progressed. Before engine control computers, electronic ignition and fuel injection, a tune up meant replacing mechanical parts that wore out. Nelsons Automotive of Pewaukee would manually adjust fuel and air mix and timing. When these adjustments were off, spark plugs would foul and need to be replaced.

This definition just doesn’t apply to modern vehicles. Service centers like Nelsons Automotive of Pewaukee generally consider a tune-up to be the major service visit, recommended by your manufacturer, every 30,000 miles or so.

Of course you can’t lubricate a sealed joint. Of course you can’t adjust a carburetor if your car doesn’t have one. You probably don’t need to change spark plugs every year if your manufacturer says they can go 30,000 miles. What are these bloggers getting so worked up about?

The danger with these modern-day myths, is that they prevent people in our local Pewaukee community from taking care of the routine preventive auto maintenance that manufactures recommend. Check out this partial list of things you still need to do to take care of your car. How many of them are really any different today than they were 20 or 30 years ago?

Oil change, cooling system service, transmission service, tire balancing, tire rotation, wheel alignment, suspension service, power steering service, proper tire inflation, brake service, differential service, battery maintenance, engine air filer, PCV valve, breather element, fuel filter, belts, hoses, timing belt, windshield wipers . . .

You get the picture. Your SUV is still a machine that needs to be maintained. And, hey, your service advisors at Nelsons Automotive of Pewaukee have always adapted to keep pace with automotive technology. Next time you come across an angry voice about your car care, talk to your Pewaukee service advisor at Nelsons Automotive of Pewaukee, or do some research of your own.

Total Vehicle Care Package

We just performed another Groupon, Total Vehicle Care Package and our customers comment was that he originally thought he was taking really good care of his vehicle until having us go through it. He was very surprised to find that the place that had been changing the oil on his higher mileage 2002 Tahoe had not noticed any of the things we pointed out. Even he had noticed the slow crank time and the sporadic low coolant light but never though much of it. The things we did find are as follows:

• The engine coolant dripping off the bottom of his engine from some kind of leak
• The very loose front wheel bearing, I mean VERY LOOSE.
• The rear air compressor that never turned on for his air shocks
• His tires that were ready for replacement even though they didn’t have many miles on them
• The front brake rotors that were rusted so badly that the inner brake pad was not touching a large part of the surface.
• His not very old battery that was failing its test miserably and needed replacement
• The leaking front axle seal and badly cracked AC drive belt.

This is a great example of why just an oil change and 23 point inspection by an uncertified tech just isn’t enough and that having a comprehensive inspection done periodically is so crucial to helping you better plan and budget for you vehicle expenses. For anyone wondering, a Total Vehicle Care Package consists of a Level 1 – 111 point inspection and an oil change, a new set of wipers and BG MOA added to the crank case. The service has a starting price of $119.95, a Level 1 Service which does not include the wipers or the MOA has a starting at price of $69.95 and is recommended to be performed as much as every 6 months depending of course on the type of driving habits. Not too much to spend to ensure safe and trouble free driving.

Fall and Spring Checkup In Pewaukee

When I was a kid in Pewaukee, my dad always made sure he took the cars in for Spring and Fall checkups. I was telling a friend that it’s about time to get into Nelsons Automotive of Pewaukee for my checkup and he said that he read on the internet that modern cars don’t need seasonal service.

My friend is (technically) right about some things, but from a practical standpoint, a seasonal check up still makes sense.

Back when my dad was teaching me about how to take care of the family SUV, most cars used a different weight of oil in the winter and in the summer. But most of today’s modern engines run the same oil year round. High-tech engines and high-tech motor oils are better able to handle the seasonal changes.

Your owner’s manual or Pewaukee service advisor at Nelsons Automotive of Pewaukee can tell you the right oil to use.

Of course, you’re concerned about the coolant or antifreeze. You don’t want to overheat in the WI summer or freeze up in the winter. Your engine cooling system protects against both of these things. And modern coolant, or as it’s sometimes called; ‘antifreeze’, is up to doing both very well. It’s designed to last for more miles than most people drive in a year or two.

So how does a Spring and Fall check-up fit in? Let’s start with Spring. Summer is coming. That means heat, more miles driven and road trips. It just makes sense to check your fluid levels and do a visual inspection to see that everything is up to snuff.

You may not be scheduled to drain and replace the coolant for some time, but you need to make sure you have enough coolant, and that you don’t have any leaks or hoses that are about to fail.

That’s pretty practical; a check-up to see if there are any problems or emerging conditions that could later become a problem, like a cracked belt.

And the same principle applies for getting ready for winter. Cold weather means lots of failed batteries. It takes more power to crank up a cold engine, and cold also decreases the available cranking power the battery has available.

So a battery test in the Fall could tell you if you’ve got a battery that is running on its last legs. And of course, if you live where winter temperatures get below 45 degrees or you have ice and snow, you’ll want to consider changing to winter tires.

So Spring and Fall auto checkups at Nelsons Automotive of Pewaukee are practical reminders to get ready for the demands of the hot and cold seasons to come.

And odds are that you have one or more routine services that are due anyway. Like a transmission service, brake or power steering fluid, differential service – stuff like that. Are your wiper blades still good? Are your headlamps starting to dim?

So Spring and Fall: change your clocks, replace the batteries in your smoke detectors – and get a check-up for your cars.

See, dad was right again.

Come and see us at Nelsons Automotive of Pewaukee for your Spring and Fall automotive checkup.
