Automotive Tips from Ken's Auto Center: Tire Replacement Overview

Tires are an expensive purchase, so knowing when tires should be replaced is important for San Diego drivers. Tires will just wear out with normal use. The depth of the tread on your tire determines how well it will stop, start and steer – especially in wet conditions. 4/32th of an inch (3.2 mm) of tire tread is considered a safe amount of tread.

Uneven tread wear can be a symptom of other problems, and simply replacing your tires will not prevent the same uneven wear from happening to the new tires. At Ken's Auto Center in San Diego, we can inspect your tires for excessive or uneven wear. Unusual wear may lead to further inspection of steering, suspension or alignment problems. We can help with necessary repairs and with getting you the right tires for your needs.

Automotive Tips from Ken's Auto Center: When to Replace Your Wiper Blades

There are several important factors that go into how often San Diego drivers should replace their wiper blades. Of course, the more you use your wipers, the faster the blades will wear out – especially if you use them on an icy windshield. Whether it’s a lot of bugs and road grime from CA freeway driving or lots of wet weather – your blades get a work out and start to wear.

But your wiper blades break down even when they aren’t used frequently. They are damaged by sunlight and temperature changes as well. The rubber in the blades can dry out and crack and eventually fall apart. Check your wipers: If they’re not doing their important job, have them replaced at Ken's Auto Center in San Diego.

Talk to your Ken's Auto Center service advisor about how you drive - we can counsel you on the optimal blades for your needs.

The Straight and Narrow: Power Steering Service at Ken's Auto Center

Service to a vehicle's power steering system is part of preventive maintenance for  San Diego auto owners. This system provides power to the steering wheel so you can turn it with ease. Without power steering, all of the power to turn your vehicle's wheels would have to come from you.

The central element of most power steering systems is a pump. The pump pressurizes the power steering fluid, and it is this pressure that provides auxiliary steering power. A belt connected to the engine usually powers the pump, although some systems use an electric pump. Some newer vehicles have an electric motor that directly provides the power steering boost.

Pressurized fluid moves from the pump to the steering gear through a high-pressure hose. A low-pressure hose returns fluid to the pump. Power steering fluid cleans, cools and lubricates the system.

San Diego drivers should remember that fluid levels in the power steering system should be checked at every oil change. Low fluid levels can damage the pump, which can be expensive to repair. Low fluid levels may also indicate a leaky hose in the power steering system, so it is a good idea to inspect the hoses, especially if your fluid levels are low.

Power steering fluid breaks down over time, losing its effectiveness. It also gradually collects moisture, which can lead to corrosion in the steering system. So the fluid needs to be replaced occasionally. You should check with your owner's manual or ask your service advisor at Ken's Auto Center to learn how often this fluid should be replaced.

When your fluid is replaced, your technicians at Ken's Auto Center will remove the old fluid and replace it with new. Power steering fluids are not all created equal; the fluid has to be compatible with your hoses and seals. Ken's Auto Center can ensure that you get the right fluid for your vehicle, or you can consult your owner's manual.

Signs that your power steering system is in trouble can include the following: a steering wheel that is hard to turn, auxiliary steering power that cuts in and out, or a whining sound coming from the pump. Also, drivers in San Diego who are not topping off the power steering fluid on schedule may hear squealing coming from the engine belts.

To protect your steering system you should never hold the steering wheel in the far right or far left position for more than a few seconds at a time. This can wear out your pump in a hurry.

Preventive maintenance for your steering system primarily involves the power steering components, but your steering system has other parts that can wear out or be damaged by rough CA driving conditions. Such parts include the ball-joint, idler arm, steering gear, steering-knuckle and tie rod. Signs that they are in need of attention include play in the steering wheel, a vehicle that wanders, uneven tire wear and a steering wheel that is off-center. San Diego drivers should have their alignment checked annually. This check-up can reveal bent or damaged steering components.

Taking the Heat (Heater Hose Maintenance/Repair)

If you have an internal combustion vehicle, you know it has a lot of hoses that carry various fluids.  And if you have a heater in your vehicle, you'll have heater hoses.

A heater hose connects to and from the engine so some coolant can be circulated through a little radiator called a heater core.  In cold weather, that heater core acts as a heat exchanger to heat up your cabin.

Even in the hot weather, the heater hoses can prove problematic.  That's because they may remain pressurized even though you're not running your heater.  Heater hoses are made out of tough materials since they must handle heat and pressure.  But even the durable rubber, plastic and metal they are made out of can crack or leak from years of use.  That means coolant can be sprayed out into the engine compartment or leak onto a driveway or garage floor. 

You may be able to see a puddle of coolant under your vehicle or perhaps smell the odor of the coolant under the hood.  Some say it has a sweet smell.  Another sign coolant may be leaking out of the heater hoses is your engine may be running hotter.   You'll be able to tell by watching the heat gauge on your dash.  Let's say your heat gauge usually points just slightly below halfway between the C and H (Cold and Hot) of the heat gauge.  But now it is just slightly above.  That's enough to tell you that the coolant temperature has gone up a little, a possible sign of trouble.

This is a good time to swing by your service facility and have them take a look. If they catch the leak when it's small, it's a relatively simple matter of draining the coolant, replacing the hoses and replacing the coolant.  Sometimes, though, a heater hose can suddenly burst and a lot of coolant can leak out quickly.  That can, in turn, cause your engine to start to overheat.  In that case, you may see your vehicle's temperature gauge shoot up pretty quickly.  Then it's best to pull over and have your car towed to a repair facility since driving with no coolant can cause severe engine damage.

Preventative maintenance is your best insurance against heater hose problems.  A technician will periodically check for any signs of cracks or leaks.  You should expect to replace a heater hose at least once during the time you own your vehicle.

Fuel Injectors

The last new American vehicles sold in San Diego with a carburetor rolled out of the CA dealerships in 1990. Since then, all new vehicles here in San Diego, and nationally, 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 injectors deliver fuel far more precisely than carburetors. That translates into better fuel economy and more power for San Diego drivers. 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 vehicle manufacturers 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 CA drivers can expect to see more of it in the future.

As San Diego residents can see, the level of precision required of fuel injectors is very high. It's important that they operate properly in order for your vehicle to run right.

High temperatures under your hood and variations in San Diego 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 vehicle fuel injectors clean.

Skilled service technicians at Ken's Auto Center in San Diego can perform a fuel system service for you. 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 San Diego gas pump and your fuel injectors. A fuel system service at Ken's Auto Center 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 for you and deliver the right amount of fuel at the right time.

Our pros at Ken's Auto Center use a process for cleaning your vehicle 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 enjoy strong performance and prevent repairs down the road.
