Power Steering Service Near RowlettOctober 23, 2012

For most of us living in the Rowlett area, 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 at Lewis Complete Auto Repair.

The fluid cleans, cools and lubricates the power steering system. It breaks down as the years go by and collects unwanted moisture, so it needs to be replaced from time to time. Many manufacturers specify power steering service intervals. Unfortunately, this important service is sometimes left off the maintenance schedule for many of us in Rowlett. So, when in doubt, every 25,000 miles/40,000 km or two years is a good fallback. Your Lewis Complete Auto Repair service center in Rowlett will use a detergent to clean the system, flush out the old fluid and replace it with the good stuff.

Here are some warning signs of trouble with your power steering: It’s harder to turn the wheel, there’s erratic power assist, you hear loud whining coming from the pump (which may be difficult to hear over the loud whining coming from the backseat), you have to top-off the fluid frequently, or you hear squealing belts. Remember to never hold the steering wheel to the far right or left for more than a few seconds at a time. That will wear out your power steering pump real fast.

Other steering components can be bent or damaged from wear or hard knocks. Ball-joint, idler-arm, steering-gear, steering-knuckle and tie rod to name a few. Warning signs here are steering play, wandering, uneven tire wear, and off-center steering wheel. An annual alignment check at Lewis Complete Auto Repair will reveal bent or damaged steering components.

Most SUV’s, pick-ups and rear-wheel-drive cars need regular front-wheel-bearing service.

The bearings should be cleaned and inspected. If they are excessively worn, they need to be replaced. The bearings are then repacked in clean grease. It’s also recommend the wheel-seal be replaced when the bearings are serviced. Like everything else, check your owners’ manual maintenance schedule. It’s usually required around every two years or 40,000 miles/64,000 km. If you drive through water in the Rowlett area, the bearings will need service more often.

PCV Valve ReplacementOctober 23, 2012

The energy from exploding fuel is what powers your engine. But some of the vapors from the explosions escape into the lower part of the engine, called the crankcase. The crankcase is where your engine oil hangs out. These gases are about 70% unburned fuel. If the gases were allowed to stay in the crankcase, they would quickly contaminate the oil and turn it to sludge. Sludge is one of the biggest enemies of your engine, clogging it up, eventually leading to expensive failures. Also, the pressure build up would cause seals and gaskets to blow out. Therefore, these gases need to be vented out.

Gasoline engines used to simply have a hose that let the poisonous fumes vent out into the air. In 1963, the federal government required gas engines to have a special one-way valve installed to help reduce dangerous emissions. Diesel engines are not required to have these valves.

The positive crankcase ventilation, or PCV, valve routes crankcase gases through a hose and back into the air intake system where they are re-burned in the engine. Fresh, clean air is brought into the crankcase through a breather tube. It’s really a pretty simple system, but does an important job. The re-circulating air removes moisture and combustion waste from the crankcase, preventing sludge. This extends not only the life of your oil, but the engine as well. The PCV relieves pressure in the crankcase, preventing oil leaks.

Eventually, the PCV valve can get gummed up. Then it can not move enough air through the engine to keep it working efficiently. If the PCV valve is sticking enough, you could have oil leaks, excess oil consumption and a fouled intake system. If you experience hesitation or surging or an oil leak, it may be a sign of PCV value problems. Your owners’ manual may give a recommendation for when the PCV valve should be replaced – usually between 20,000 mi/32,000 km and 50,000 mi/80,000 km. Unfortunately, some manufacturers don’t list a recommendation in the manual, so it can be easy to overlook.

Many PCV system problems can be diagnosed with a visual inspection. Fortunately, PCV valve replacement is both quick and inexpensive. Proper oil changes will greatly extend the life of the PCV valve. Skipping a few recommended oil changes can allow varnish and gum to build up in the valve, reducing its efficiency. So now when your Rowlett service technician tells you its time to replace your PCV valve, you will know what he’s talking about. If you have had your car for a while and this is the first you’ve ever heard of a PCV value, ask your tech to check yours out or call Lewis Complete Auto Repair at 972.475.4800.

Air Conditioning Service In RowlettOctober 23, 2012

Hey Rowlett, TX 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 in Rowlett 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, making it work harder to cool the air. 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 should also run the air conditioner regularly, even in a frosty Rowlett winter, so that it lubricates itself and keeps the seals from drying out, which leads to leaks. Your owner’s manual will have recommendations for how often to service your air conditioner. Of course, if it’s not working right, now is the time to get it checked. Lewis Complete Auto Repair can inspect and test your air conditioning and offer evacuation and recharge services. This goes a long way to avoiding having to bring your air conditioner in for major repairs.

New environmental laws have stopped the manufacture of Freon, a refrigerant that was common in cars made before 1993. There is a very limited supply of Freon so the price is very steep. It may not be worth its weight in gold, but it probably is worth its weight in silver. If you have an older vehicle that uses Freon, you may want to consider having it retrofitted to use the new R134-A refrigerant. It will pay for itself in the long run. So, if your AC is just a lot of hot air, bring it in to Lewis Complete Auto Repair for an inspection.

Braking News: Keep Your Stopping PowerOctober 23, 2012

Richard Petty once told AutoNetTV, “You’ve gotta have good brakes. If you’ve got good brakes you can keep yourself out of a lotta trouble.”

That’s why a regular brake inspection is on every Rowlett car’s maintenance schedule. An inspection at Lewis Complete Auto Repair will check your brake system and let you know if there are any problems.

Of course, if you’re having trouble with your brakes, get your car into Lewis Complete Auto Repair right away. Here are some symptoms to watch for:

  • Low or spongy brake pedal
  • Hard brake pedal
  • A brake warning light that stays on
  • Constantly squealing or grinding brakes
  • Vibrations or clunking sounds when you apply your brakes

If you are experiencing any of these, it’s time to get your brakes checked.

There are two types of brakes: disc and drum. Disc brakes have a rotor that’s attached to the axle. Calipers straddle the rotor, kind of like the brakes on a bicycle.

Drum brakes are more common on back wheels. Both types have pads or shoes that press against the brakes and slow the vehicle. Brake pads and shoes are made out of very tough material to withstand the heat and force generated when stopping your car. Eventually, they wear out with use, and become too thin and need to be replaced.

If the brake pads wear away completely, you can damage the rotors. The calipers can grind grooves in the rotor. Then the rotor must either be resurfaced or replaced. That’s not only expensive, but also dangerous because your vehicle won’t stop as quickly. Sometimes rotors warp or crack and must be replaced.

Brake service will also include a check of your brake fluid. When the brakes are applied, the pressure in the fluid actives the brake pads or shoes. Not enough fluid means not enough pressure to brake properly. Also, water builds up in the brake fluid over time, which leads to corrosion, leaks and brake damage, and with hard use, the brakes could severely fade or even fail. You should change the brake fluid when your manufacturer recommends to avoid these problems.

There are different grades of brake pads; good, better and best. Higher grades cost more, but give better braking performance and smoother operation. It’s OK to upgrade your brake pads. But, never use a grade that’s lower than what the manufacturer recommends.

So, be sure to properly maintain your brakes, because it’s a lot cheaper than paying the body shop after an accident.

Come in to Lewis Complete Auto Repair for an brake inspection before damage occurs. You can call ahead for an appointment by calling 972.475.4800.

Cabin Air Filter From Lewis Complete Auto RepairOctober 23, 2012

What is a cabin air filter?

Is it:

  1. A filter for a house in the middle of the woods?
  2. A fresh, piney scent?
  3. 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 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 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 for a recommendation. It’s usually every year or 12,000 miles/ 19,000 kilometers. Change it sooner if you drive in dusty conditions 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 more enjoyable.
