Lancaster Car Owners Ask: Why Do I Need to Change My Serpentine Belt?

Jul 25, 2016

Any Lancaster driver who understands preventive maintenance knows that “if it ain't broke, don't fix it” is bad auto advice. Replacing a part before it breaks is much less costly for Lancaster residents than repairing the engine damage that comes after a part breaks or fails. A good example of this is the serpentine belt.

The serpentine belt gets its name because of its circuitous path around the engine. The serpentine belt is driven by the engine and powers a number of systems, as follows:

1. The serpentine belt spins the compressor that generates the cool air for the air conditioning system.
2. The serpentine belt powers the alternator. The alternator generates electricity for use in the vehicle's electrical systems and to charge the battery. Without the alternator, the battery wouldn't last more than a few miles.
3. In many Lancaster residents' vehicles, the serpentine belt runs the pumps for both the power steering and the power brakes. In other vehicles, the power steering pump may be electric and the power brakes may use a vacuum boost.
4. On many vehicles, the serpentine belt powers the water pump. The water pump keeps coolant circulating through to maintain appropriate operating temperatures. In some California vehicles, a timing belt runs the water pump.

When a serpentine belt fails, all of these systems fail as well, which can lead to engine impact.

Replacing parts before they break saves money for Lancaster residents by preventing more repairs and the frustration of having your vehicle in the shop for an extended period of time. If you're looking for an adage to apply to good car care, you might remember the old story of how “for want of a nail, the kingdom was lost.”

Time for Differential Service at The Car Doctors of the Antelope Valley?

Jul 17, 2016

Hello Lancaster - let's talk differentials. If you have a rear-wheel drive vehicle, your differential is on the back axle. With front-wheel drive cars, the differential is up front. All-wheel drive and 4-wheel drive vehicles have three differentials - front, rear and in the middle. So you see, you've got a differential (or two or three) and it needs service now and then.

What does your vehicle differential do? Well, it compensates for the differences in speed between your outer and inner wheels in a turn. Using the dimensions of a typical car, let's compare the distance the wheels travel from the start of a turn through to the completion of the turn.

The inside wheel travels about 12.6 feet/3.8 meters. How much farther does the outside wheel travel? About 18.8 feet/5.7 meters – over 6 feet/1.9 meters more. This means the outer tire has to rotate 9 times in the same amount of time that the inner tire has to rotate only 6 times - so the outer tire has to spin faster in order to keep up. The differential makes this possible.

The gears in the differential are cooled and lubricated by differential fluid. It's this fluid that needs to be serviced. Small bits of the gears break off and are suspended in the differential fluid. The dirtier the fluid, the faster the gears wear.

So your The Car Doctors of the Antelope Valley technician drains the old fluid out and replaces it with fresh fluid. Some differentials also need a special additive that is put in at this time.

So when should you have your vehicle differential serviced? Intervals vary from vehicle to vehicle – and may be as short as 15,000 miles/24,000 km – so check your vehicle owner's manual or ask us at The Car Doctors of the Antelope Valley. If you frequently drive with heavy loads, tow a trailer or drive in hot California conditions, you may need to change differential fluid more often. Servicing your differential on schedule at The Car Doctors of the Antelope Valley can save a pricey replacement down the road.

Need a New Battery? Call The Car Doctors of the Antelope Valley Today

Jul 12, 2016

Hello Lancaster drivers! Need a new battery? There is a good chance that you do – 70% of batteries need to be replaced within four years. As your battery discharges and then recharges as you drive around Lancaster, bits of the surface of the battery plates disintegrate. As this process continues over a few years, the alternator has to work harder to supplement the battery charge. Over time, enough of the battery is damaged that it can no longer hold a charge and it needs to be replaced. This also speeds up wear on the alternator.

Your The Car Doctors of the Antelope Valley service advisor can help you determine the right vehicle replacement battery for the way you drive around Lancaster, as well as the California climate and durability needs.

Contact The Car Doctors of the Antelope Valley for information on battery replacement.

Beware of Cheap Tires in Lancaster

Jul 06, 2016

Do you like to shop for shoes in Lancaster?
When buying a running shoe, is quality important?
Does durability matter as long as the shoes look fabulous?
Would you rather have one pair of long lasting shoes or two pairs of lower quality shoes at the same price?

Is the warranty important when buying tires?

Lancaster drivers should also think about the safety aspect of tires. The tires do a lot of work – they carry the weight of the vehicle and you and your passengers. You want to be sure they hold the road and provide good traction on California freeways and surface streets. If you carry heavy loads or tow a trailer on California highways, the tires need a high load rating.

Ask your friendly and knowledgeable Lancaster tire professional at The Car Doctors of the Antelope Valley. I think it's important that Lancaster residents understand the effect of price on a tire's quality, performance and durability. When I was a kid, my dad would say, “Pay twice as much and buy half as many.”

The same principle applies to tires. The major tire brands that you're familiar with in Lancaster are known as Tier 1 tires. These tires are high quality and well-engineered. Comparable vehicle Tier 1 tires are usually priced similarly.

Stepping down, you come to private label tires. Some large California tire store chains carry tires with their own brand. It's important to know that most private label tires are built by the same Tier 1 companies that you are familiar with – so you are pretty safe in choosing them. To be sure, you can ask your The Car Doctors of the Antelope Valley tire professional which manufacturer makes their private brand.

The lowest priced tires on the market in Lancaster are Tier 3 tires which are usually imported from China or South America. Since you get what you pay for, you can't expect a Tier 3 tire to deliver the same performance and durability as the others.


What's the difference in the tires with high mileage warranties? It's the rubber compounds and the amount of tread material. As you might expect, you'll pay more for the longer-lasting tire.

Your tires are the only parts of your vehicle that touch the road. You're only as safe as your tires are well built. Buy value – not price.
