We would like to give you an update on some of the things happening in automotive fluids. You know, cars are becoming more sophisticated everyday - and fluids such as, oil, coolant and transmission fluid are becoming more specialized at about the same pace. The do-it-yourselfer has to be pretty careful so that they do not actually harm their vehicle with the wrong type of fluid. That is why so many CA car owners rely on the advice of their service consultant to not only get the correct family of fluids, but to suggest the formulation that is best for their car and the way they drive. Let's start with engine oil. If you have been paying attention, you will have noticed a number of new oil weights on the scene in the last several years. Modern engines are built to much tighter tolerances and have very complicated valve trains. The oil must be thin enough to lubricate complicated parts when the engine is cold. The weight of an oil is expressed in terms like 20-W-50 or 5-W-30. Manufactru ... read more

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 do ... read more

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 ... read more

What is a cabin air filter? Is it: A filter for a house in the middle of the woods? A fresh, piney scent? A filter for the passenger compartment of your car? Clever you, it's 3. A cabin air filter cleans the outside air before it comes into the passenger compartment. It filters out dust, pollen, spores, bacteria, pollutants, sparrows, exhaust gas and odors. These high tech filters can block particles larger than 3 microns. By contrast, a grain of sand is about 200 microns. Now not all vehicles have cabin filters. They are fairly new on the scene. About forty percent of new vehicles in CA 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 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 ... read more

Here at AutoNetTV, we have viewers, like you, from all across the country who write to us with questions or feedback. One common question we're asked is: What is a differential and what does it do? You may have been told your differential needs service, or seen it as an option up on the service menu. Differential service covers a lot of things, so let's first talk about what a differential does. As you drive through a turn, your outside wheels and inside wheels turn at different speeds. Kind of like the cars going around a race track - the ones driving in the outside lanes have a greater distance to travel than the cars in the inside lanes. The differential is what allows the outside and inside drive wheels to rotate at slightly different speeds so that the tires don't hop or skip while taking corners, or lose traction in dirt or snow. Differentials have gears in them that transfer the power fro ... read more

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 manufactruers 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 manufactruer recommends you have your emission system checked out by a qualified Van Nuys 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 ... read more

You may know that most automotive failures are tire related, but do you know the second most common cause for vehicle failure? Nope, it's not teenagers. It is the coolant system. But, if you take good care of your coolant system, it will take good care of you. A car's engine creates a lot of heat - so much heat, that if it is not properly cooled, the engine can lock up, resulting in massive damage and repair bills. But when everything is working right, your engine operates at the proper temperatrue and all is well. Without antifreeze in your cooling system, the water could freeze and cause engine damage. This could be very expensive, not to mention inconvenient. The right mix of water and antifreeze protects the engine against damage from freezing and overheating. Antifreeze also protects the coolant system against corrosion that could cause the system to fail. The thing to re ... read more

You would never like to drink a glass of mud, right? Well, your car feels the same way. It needs a steady supply of clean fuel in order to run well and deliver good fuel economy. The fuel filter's job is to clean dirt and rust out of the fuel before it gets to your engine. A clogged fuel filter can actually choke off the engine so that it won't start or run. Some fuel filters have a bypass valve that allows fuel to go around the clogged filter so your car will still run. But, then the contaminated fuel can plug your fuel injectors and allow damaging particles into your engine. A car with a partially clogged fuel filter might run well around town, but sputter and strain on the highway because it's starving for gas. There are two things that affect how often you need to replace the filter. They are: where you drive and the g ... read more

Nothing in your engine workers harder than your oil. With hundreds of moving parts, and thousands of explosions every minute, it's no wonder that engine oil needs to be changed frequently! You've probably heard the old rule of thumb: Change your oil every 3,000 miles/ 5,000 kilometers or 3 months, whichever comes first. But some car manufactruers have introduced extended oil change intervals. They figure that a modern vehicle driven under the right conditions can go for 5,000 miles/8000 kilometers or more between an oil change. The key phrase here is "under the right conditions". If you look at your owner's manual, you'll see two different maintenance schedules: one for "normal" driving conditions and one for "Severe Service". Severe service driving conditions include stop and go, short trips, towing, hauling, hot, cold, and dusty driving. That's why at AutoN ... read more

Working up a sweat is a great thing to do in a gym, but not in your car. When your car's AC System has a problem, you'll often feel it right away. The question is, how long do you put up with it? You know, the old comfort versus cost dilemma. But a more comfortable drive has a lot of benefits, and keeping the AC System well maintained can help prevent expensive repairs. A common cause for AC failure is water and air in the system. The system does not 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 try to cool the air. That is why 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 sh ... read more
