Cabin Air Filter

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

Differential Service

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

Exhaust Service

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

Coolant Antifreeze Service

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

Fuel Filter Replacement

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

Risk of Extended Oil Change Intervals

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

Air Conditioning Service

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

Battery Replacement

Modern cars and trucks run on 12 volt electrical systems. 12 volts is enough to get the job done without having so much power that there is danger of electrocution. But today's vehicles have more electrical components and do-dads than ever before. This really strains your electrical system, making it hard for the battery to keep up. Think about it: electric seats, seat heaters, power locks, windows and sun roofs. And then we have all the power outlets for our cell phones, computers, and DVD players. We also have navigation systems and powerful stereos. Plus there are all the engine and transmission computers, traction control, stability control, anti-lock brakes, sensors and on and on. Even the security system is running off the battery while the car is turned off. Fortunately, battery technology has given us resilient batteries that are able to meet these strenuous requiremen ... read more

Custom Wheels and Tires

One of the most popular vehicle modifications in CA is custom wheels and tires. Custom wheels help you stand out from the crowd without spending a lot of money, and custom tires can help you fine tune your performance. Not that long ago, new cars came with just one or two tire and wheel options. Now manufactruers are offering more choices and over a third of new vehicle buyers choose custom wheels. That seems to have fueled public demand for custom wheels in all vehicle categories. The available styles, colors and finishes are endless. You're sure to get the look you want - from sleek and stylish to tough and aggressive. While custom wheels are largely a matter of taste, custom tires are a matter of function. That is not to say that there are not a lot of cool looking tires out there, it's just that tires are vital to your safety, so there are some important practical considerations. Let's look at it in terms of extremes. Think about the enviro ... read more

OE vs. Aftermarket

CA new car dealerships are happy to leave you with the impression that you should have all of your scheduled automotive maintenance performed at the dealership during the warranty period. Some go so far as to imply that your warranty protection depends on it. In fact, nothing is further from the truth. Federal laws in both the United States and Canada specify that you do not have to have your vehicle serviced at a dealership to maintain warranty protection. The laws further state that a vehicle manufactruer cannot mandate that you use their particular brand of replacement parts or fluids. This certainly means you have many more service options, but what about quality? First off, it is important to know that vehicle manufactruers do not make all of their own parts. They look to thousands of independent suppliers to manufactrue the parts that go into your car or truck. Many of these same manufactruers that make the parts that are original equipme ... read more
