What Is That? Check Engine Light Service at Kingwood Service Center

Okay. You went to your local Kingwood car wash, and while your vehicle was under the dryer, the Check Engine light started flashing. Panic! What did you just do? Something is seriously wrong with the vehicle! You head for the nearest Kingwood service center, but on the way, the Check Engine light stops flashing and just glows red. Hmm. Maybe things aren't as bad as they seem. You decide to wait until payday to take your vehicle in to get serviced. In the meantime, the Check Engine light goes off. What? You decide the light must be faulty; maybe when it comes on it doesn't mean anything, or maybe it's just in your vehicle as some sort of scam to get you to pay for unnecessary repairs. You're glad you didn't take your car to the Kingwood repair shop and resolve to ignore that Check Engine light in the future.

Whoa! Let's look at what really happened. Your vehicle was under an air dryer. Your air intake sensor measured too much air running through the engine. It sent its report to the engine computer, where a warning was triggered; there shouldn't be that much airflow when the vehicle engine is idling. This is a serious problem that could cause permanent engine damage. Warning! The Check Engine light starts flashing, letting you know you need to take immediate action to prevent that damage.

You drive out from under the dryer, and the air intake sensor sends a new message to the computer. The computer realizes that everything is normal and tells the Check Engine light to stop flashing. The vehicle doesn't need immediate attention; but there was a problem, and it should be checked out by your Kingwood Service Center service advisor. After a few days the computer senses that the problem is gone, so it turns off the warning light.

You may think this story illustrates the uselessness of a Check Engine light, but you should remember that a computer can't think for itself; it can only follow its programming. It doesn't know the difference between a car wash air dryer and a serious malfunction in your vehicle engine. That doesn't make it useless. It just means you have to be the smart one.

Being smart doesn't mean ignoring your vehicle Check Engine light. It lets you know when something is wrong, and you can prevent a lot of damage to your vehicle by paying proper attention to it.

Your engine computer is constantly collecting data about what is going on inside your vehicle engine. It knows what parameters are normal and when a reading may indicate a problem. It uses the Check Engine light to let you know when something isn't right. It then stores a code in its memory — which a technician can retrieve — that indicates which reading was abnormal.

The technician uses this code as a starting place to find out what's wrong with your vehicle. It's like going to the doctor with a fever. The fever is the reading that is abnormal — your temperature is too high — but the doctor still has to figure out what's causing it. It's probably an infection, but what kind? Sinus infection? Appendicitis? Flu? The problems and their solutions are quite different. But a fever also tells a doctor what's NOT wrong with you. Fevers don't accompany stress headaches, ulcers or arthritis, so there's no sense in testing for those conditions.

The pros at Kingwood Service Center respond to a trouble code in your vehicle's computer in the same way. The code doesn't say exactly what's wrong, but it does give the technician a good indication of where to start looking —and where he/she doesn't need to look.

Now, you wouldn't consider diagnosing yourself with a serious medical problem — good medical advice unless you're a doctor. So you shouldn't consider trying to diagnose your vehicle's troubles by yourself — good auto advice unless you're a trained mechanic.

There are cheap scanners available on the market, and some Kingwood auto parts stores offer to read trouble codes from your vehicle engine's  computer for you. But these are really not good alternatives to taking your vehicle to a qualified service center such as Kingwood Service Center in Kingwood. Your engine's computer has both short-term and long-term memory, and there are some codes that are specific to a particular make of vehicle. Cheap scanners can't read an engine computer's long-term memory nor can they interpret manufacturer-specific codes. That's why our manager at Kingwood Service Center spends a lot of money on high-end diagnostic tools.

It's as if you had a choice between a doctor who had a tongue depressor and a thermometer and one who had all the latest medical diagnostic equipment on hand. Honestly, which would you choose?

Getting your codes read at your Kingwood area auto parts store isn't really a money-saver, either, unless you're a trained mechanic. You'll end up with a code that tells you a symptom. What usually happens next is that the Kingwood area parts store sells you something that directly relates to the symptom. It may or may not fix the problem. It's actually cheaper to just go to Kingwood Service Center and get things fixed right the first time.

Remember, a fever can indicate a sinus infection or appendicitis. An antibiotic may be okay for that sinus infection, but it likely won't help your appendicitis. Is it really wise to wait around to see if the antibiotic helps when you might have appendicitis?

Part of good vehicle care is knowing where you can get a problem fixed — and fixed right. Preventive maintenance goes a long way to keeping you out of the repair shop, but eventually, we will all have a problem that needs fixing. Let's do it right the first time at Kingwood Service Center.

The Right Fluids for Your Vehicle

The current vehicles in the market have over a century of engineering behind them. They have evolved into complex and powerful machines. Developments in their engines, however, have coincided with advances in many other vehicle components, including the fluids.

It's up to people in Kingwood to always use the right type of fluid for their vehicle. Your service advisor and your owner's manual are resources for auto advice on exactly what types of fluid your vehicle needs. Improper fluids can damage your vehicle and void your warranty.

Some of the fluids that have changed significantly in recent years are cooling system fluid, brake fluid, transmission fluid and motor oil. Each of these comes in many varieties now, and it's hard to know exactly which one your vehicle needs.

Cooling systems were once made of iron, steel and rubber. One coolant could be used to protect all of these materials. But new cooling systems have components made from a variety of metal alloys and several kinds of plastic, and coolants now contain additives that protect these various materials from corrosion. Since the materials vary among manufacturers, they require different additives, which means there are now several coolants on the market. The type of coolant your vehicle needs depends on the materials used in its cooling system.

Most vehicles used to require DOT 3 brake fluid. But now many vehicles need DOT 4 or DOT 5. Some Kingwood drivers mistakenly think the higher numbers reflect an increase in grade—that DOT 4 is somehow better than DOT 3. But the truth is, the numbers represent variations in formulation. The different formulas have evolved to meet the demands of newer and better brake systems. For a long time, transmission fluid came in two varieties: regular and friction-modified. But transmissions have come a long way recently and so have the fluids that protect and lubricate them. There are several new types of fluid on the market, but your vehicle is designed for just one of them.

Of all the automotive fluids, motor oils have experienced perhaps the greatest advances in engineering and technology. A number of new weights and formulations have recently been developed to meet the needs of modern engines, which have more parts and tighter tolerances than ever before. Engines have become more sophisticated and complicated, but they have also increased in power and fuel efficiency. Despite these changes, Kingwood vehicles still need them to be highly durable.

That's the job of motor oil. Motor oil still has to perform its original function—lubricating and protecting the engine. It is formulated to help clean the engine as well. Modern motor oil also has to be thin enough to penetrate small engine passages yet still be resistant to vaporization.

Specialized motor oils have also been developed for high-mileage vehicles. If your vehicle has 75,000 miles/120,000 km or more on it, you might consider switching to one of these motor oils. They contain extra detergents that help clean older engines, additives that condition seals and gaskets that can become brittle with age. High-mileage motor oils come in weights and types just like regular motor oils, and Kingwood drivers should match the proper weight and type of high-mileage oil to their vehicle in the same way you would regular motor oil.

Over time, vehicles have developed in complexity and variety, and their fluids have developed as well. Each vehicle is matched to a set of fluids that meet its specific requirements. TX vehicle owners should take care to learn their vehicle's fluid requirements before topping off at home. A large part of preventive maintenance for Kingwood drivers is making sure your vehicle's fluids are clean and adequate, but they must be the proper type as well. As our vehicles become more sophisticated, car care becomes more sophisticated as well.

Learning about proper fluids for your vehicle will help you maintain its performance and prolong its life. Talk to us at Kingwood Service Center in Kingwood.

Does My Choice in Oil Affect Change Intervals?

Oil changes are probably the most recognized service on a vehicle. Almost all Kingwood residents know about them. But do we know enough?

Several decades ago, oil changes were fairly standard: every three months or 3,000 miles or 5,000 kilometers. But recent advances in both engine technology and oil quality have led to longer oil change intervals.

Delayed or skipped oil changes are a problem for Kingwood residents because they lead to the build-up of oil sludge in your engine. Oil sludge forms when engine oil breaks down, which happens with both time and miles. Obviously, driving will take its toll on engine oil, but the oil also breaks down even as the vehicle just sits in the garage. This is why oil change intervals are listed in both time and distance traveled, and the phrase “whichever comes first” is applicable.

Oil sludge is essentially petroleum jelly. Imagine this stuff squishing around in your vehicle engine, pushing into small engine passageways and blocking passage of oil to vital engine parts, shortening your engine's life expectancy.

To prevent sludge, you have to get your oil changed regularly, as often as the manufacturer recommends. Check your owner's manual for every vehicle you own to know the interval for each one. Don't assume they will be the same.

If you tow a trailer, haul heavy loads, make a lot of short trips around Kingwood, usually engage in stop-and-go (or around-the-town) driving, drive in cold or hot TX weather, or drive in polluted or dusty conditions, you may need to change your oil more frequently. Check your vehicle's owner's manual for a “severe service” recommendation.

If the manual doesn't give you the advice you need, talk to your friendly and knowledgeable Kingwood Service Center service advisor. He will be able to answer any questions about preventive maintenance or vehicle care that you may have, including how often to change your oil.

Kingwood residents need to get the right weight and type of oil recommended for their vehicles. More and more are using synthetic oil in their vehicles. Synthetic oil typically lasts longer and is more resistant to sludge formation than conventional motor oil. But it is also more expensive. So it can be tempting for Kingwood residents to ask for conventional oil, but if you replace synthetic oil with conventional oil, you will have to change your oil more often to prevent sludge build-up. In the end, you're probably not saving money at all.

Also, your engine may not be designed for the conventional oil. Check your owner's manual before replacing synthetic oil with conventional.

Talk to your Kingwood Service Center service advisor for more information.

Positive Crankcase Ventilation ? PCV Valve Service at Kingwood Service Center

Hello Kingwood! Did you know that the first federally-mandated emissions control device was introduced in the 1960's? The Positive Crankcase Ventilation valve, or PCV valve, has been installed in TX vehicles since 1964 and represents the first legislation by the United States government to regulate harmful emissions as well as to improve performance in the country's vehicles.

The PCV valve, as you can probably guess, is located on the crankcase. The crankcase is the lowest part of a vehicle's engine. It houses the crankshaft and the engine oil. The crankshaft connects to the pistons that power the engine.

Pistons are pushed down when fuel is burned in an engine. This causes the crankshaft to rotate, which sends power to the transmission.  It ultimately turns the axles and causes the vehicle to move. Some of the gases released by the burning fuel squeeze around the pistons and down into the crankcase.

If the escaped gases mix with the engine oil in the crankcase, oil sludge develops. This sludge has the consistency of petroleum jelly and can cause damage by clogging up passageways in the engine. Further, escaped gases can build up pressure inside the crankcase that can blow out seals and gaskets.

Before 1964, a hose was attached to the crankcase that vented escaped gases out into the air. These gases contained about 70% unburned fuel as well as harmful emissions. The PCV valve was designed to curb these harmful emissions as well as recapture unburned fuel.

The PCV valve is a small, one-way valve that allows escaped gases to exit the crankcase. The gases are then routed into the intake system so they can be re-burned in the engine. Fresh air enters the crankcase through a breather tube to facilitate this circulation and keep the air in the crankcase clean.

The PCV valve, like most working parts on a vehicle, will wear out over time. Usually it simply gets gummed up. Preventive maintenance, including routine oil changes at Kingwood Service Center in Kingwood, will extend the life of the valve, but eventually it will have to be replaced. A sticking PCV valve won't allow gases to circulate properly, which can increase pressure in the crankcase. Over time, that pressure will lead to oil leaks.

Your vehicle manufacturer recommends that a PCV valve be replaced every 20,000 to 50,000 miles (32,000 to 80,000 kilometers), depending on the vehicle and Kingwood driving conditions. It's an inexpensive repair but may not be included in the maintenance schedule in your owner's manual.  So if you're looking for auto advice about the PCV valve, you may have to ask our pros at Kingwood Service Center.

Taking care of our PCV valve protects the environment in TX and improves vehicle performance. It's just part of good vehicle care for Kingwood drivers and a way all of us can do our part to improve the world we live in.
