Our cars have to operate in a wide range of Houston, TX temperatures and our engine coolant must be able to perform ‘no matter what’. Think for a moment about the environment where the coolant works. Very hot, high pressure, corrosive…

And all the while, it has to protect the components of the cooling system from corrosion. These components are made from steel and aluminum, plastics and rubber. The coolant has to be formulated to protect against corrosion for all of these different materials. That’s why different manufacturers recommend different types of anti-freeze for our Houston, TX vehicles.

There are several different ‘families’ of anti-freeze available to us here in Houston, TX. Your owners’ manual will tell you what kind you should use. Of course, Mobile Tune Up and Repair will know what to put in your car.

It’s important to stay on top of this because coolant system failure is the most common mechanical problem people have here in Houston, TX. Regular service at Mobile Tune Up and Repair needs to be done to avoid failures and also to keep your warranty in place.

While the specifics of the service required may vary from vehicle to vehicle, your service consultant at Mobile Tune Up and Repair will know what to do. You’ll be advised to replace the coolant at specified intervals.

Some manufacturers may recommend periodic coolant system flushes. A flush adds a cleaning step to the fluid replacement process. Again, check to see what your service consultant recommends.

Someday, you may have to deal with an overheating problem, so you need to know what to do if your coolant temperature warning light comes on or your temperature gauge is in the hot zone.

Now, overheating can be very expensive. You can literally melt down your engine and have to replace the whole thing. So take the warning signs seriously and take immediate steps.

First turn off the air conditioner. This will lower engine temperature right away. Next turn your heater to maximum heat and run the fan at high speed. You might need to roll down the windows, but this will take a lot of heat off the engine.

Pull over as soon as you can safely do so, especially if you are stuck in slow-moving traffic, and shut the car off. It may take as much as 45 minutes for the engine to cool to the point that it’s safe to operate the car again.

If you need to add water or antifreeze, be sure to wait until the car cools down. Opening the radiator cap or even the overflow bottle when the coolant is hot and under pressure may result in serious burns.

So after the engine has cooled for 45 minutes or so, look to see if the coolant is low in the overflow tank. If so, you can cover the overflow tank cap with a large cloth and open the lid. Then start the engine and pour in some water or antifreeze. Pouring it in when the car is running will circulate the new, cool fluid with the warmer fluid in the engine and avoid engine damage.

Of course, overheating is a serious problem and you need to get it fixed right away. Mobile Tune Up and Repair can make sure the coolant is right before you drive home.

Those spring and winter inspections really come in handy when they head off a cooling system problem. And don’t forget that severe service driving conditions, like towing or hot, dusty driving around Houston, TX, mean that you’ll need to service your coolant more frequently.

At AutoNetTV, we suggest that you have Mobile Tune Up and Repair inspect your coolant system to find small problems before they become big, and to change belts and hoses before they fail. After all, we don’t want you to lose your cool out there in Houston, TX.

Your cooling system is very important. It circulates coolant through the radiator and your engine to protect your car from overheating. There are five main components to the cooling system:

the radiator
the radiator cap
the hoses
the thermostat and
the water pump
The water pump’s like the heart of your cooling system, circulating the fluid throughout. It’s a small pump that’s driven by the engine; usually by belt, but sometimes by a chain or gear.

The water pump only operates when the engine’s running. Water pump failure is pretty routine. Some start failing at around 40,000 miles, but most fail by 100,000 miles. Consult your owners’ manual or service technician to see what’s recommended.

Since a water pump either works or it doesn’t, you need to change it when it fails. Water pumps fail in one of two ways: the bearings fail or they begin to leak. It’s possible to have a leak from a cracked water pump, but it usually leaks at the gasket where it attaches to the engine.

So how can you tell when the water pump is failing? If you can hear a low-pitched grinding sound coming from the water pump – it’s got a problem. If you can see coolant in that area, you’ve got a leak.

Some water pumps are driven off the timing belt. They might be under a plastic cover so you can’t see the water pump. Look for coolant on the driveway. If you see some, have your service center check it out.

Most timing belts need to be changed at 60,000 miles – some longer. It’s a good idea to change your water pump at the same time if it’s one of those that’s driven off the timing belt. To start with, 90% of the work’s already done with the timing belt change. And, if you don’t, and develop a leak later, you’ll have to change the belt again along with the water pump because the belt will have been contaminated by the leaking coolant.

You can replace your water pump with a brand spankin’ new one or with a rebuilt pump. Rebuilt will save you some money, but ask your technician what he thinks. Don’t feel too bad if your water pump gives out. They will all wear out eventually. Your service technician can get you back on the road and on with your life.

Warm weather or cold, Houston drivers still need to think about their family car’s air conditioning. Most Houston people don’t service their air conditioning until after it fails. At Mobile Tune Up and Repair, we can advise you on your vehicle manufacturer’s preventive maintenance schedules for air conditioning service, just as we do for transmission service, oil changes and so on.

Maintaining your air conditioning system means that you always have enough refrigerant to properly do the job. Small leaks in the family car’s air conditioning system allow the refrigerant to escape and the system can’t cool the air as well. We see that a lot at Mobile Tune Up and Repair in Houston.

The refrigerant also contains a special oil that lubricates air conditioning components, and keeps the seals resilient. Low refrigerant and lubricating oil means that the air conditioning parts will wear out prematurely, and all Houston car owners know that air conditioning repairs can be costly. At Mobile Tune Up and Repair, we recommended that the air conditioner be run regularly, even during winter months, to keep the parts and seals lubricated.

Corrosion is what leads to many air conditioning system failures for Houston motorists. The small leaks mentioned earlier also mean that air and water can leak into the air conditioning system. This can lead to rust and dirt in the internal workings of the air conditioning components. This greatly accelerates wear and, ultimately, failure.

Air conditioning service at Mobile Tune Up and Repair starts with a visual inspection of the components for signs of damage or leaks. The compressor is driven by a belt from the engine, most often the serpentine belt, so it’s inspected for cracks or wear. The air conditioning compressor and other components are checked for proper operation. Then comes the leak test. If a leak is detected, often in a hose or connection, it’s repaired and the system is retested.

Then the old refrigerant is evacuated and the system is recharged with clean, fresh refrigerant. A final test insures that the family car’s air conditioner is working, and you’re on your way.

How often this should be done varies from vehicle to vehicle. Your family car owner’s manual will have the manufacturer’s recommendation and, of course, your Mobile Tune Up and Repair service advisor can tell you. It’s typically every two years.

If you’re not getting enough cool air you know something’s wrong. Also, if you hear strange sounds when you turn the air on, there might be a problem with the compressor and you should get it checked out at Mobile Tune Up and Repair. Replacing a bad A/C clutch in a family car is cheaper than waiting for it to ruin the compressor.

Houston drivers need to be aware that there’s one more thing that isn’t directly related to air conditioning service, but does impact the quality of the air in your family car. And that’s your cabin air filter. This filter cleans dust, pollen, pollution and other impurities in the air that comes from the heater and air conditioner. The cabin air filter needs to be replaced when it’s dirty. If you don’t it’ll start to smell. Not all vehicles have one, so ask your Mobile Tune Up and Repair service advisor to check your cabin air filter at the same time they’re doing your air conditioning service.

One topic that hits the news in Houston on a regular basis is the price of gas. The answer for some people in Houston is to buy a more fuel efficient vehicle. For the rest of use, we need to improve our fuel economy anyway we can.

Following recommended service intervals by coming into Mobile Tune Up and Repair is one of the best ways to keep your car running efficiently. That means better fuel economy. When you give it some thought, it only makes sense. Dirty oil or transmission fluid can’t lubricate or clean. That means more drag which reduces fuel economy.

Keeping up with scheduled oil changes and transmission services will save gas.

Dirty engine air filters are another efficiency pirate. They rob your engine of enough air to effectively burn the fuel, so you need more gas to get the job done. Replacing a dirty air filter can pay for itself in fuel savings before the next oil change.

You can imagine what dirty fuel injectors can do to your family car as you drive around Houston. If your owner’s manual recommends a fuel system cleaning, come into Mobile Tune Up and Repair and ask us to get it done for you.

A simple, but very effective way to save gas is to keep your tires properly inflated. Low tires can cost you up to a mile per gallon. Check your tire pressure when you gas up – or at least once a month.

Most folks around Houston have had a flat tire. You know it’s inconvenient and a pain. Our tires are important. Keeping them in good working order isn’t just a big safety issue – it also has a financial impact. With high gas prices, we’ve all heard about the importance of keeping proper tire pressure to save on gas. In addition, proper inflation promotes even tread wear so your tires last longer.

There’s another danger to under-inflated tires. Low tire pressure puts added stress on the structure of the tire itself, causing it to break down prematurely. Also, under-inflated tires generate more heat which also reduces tire life. So get those slow leaks fixed quickly – don’t just keep airing them up every few days. You want to avoid serious tire damage.

Tires can also be damaged by road hazards in and around Houston. Punctures, cuts and impacts on curbs or potholes can also cause damage that could lead to tire failure. Sometimes, it’s something that a visual inspection would reveal. Take the opportunity to check your tires when you’re gassing up. Look for slashes, missing chunks, nails or screws in the tread or just uneven wear. Of course check the air pressure too.

Now tire damage can be on the inside where you can’t see it until it’s removed from the wheel. Such damage could come from a severe impact, driving on a flat or even just low pressure. Some punctures can cause internal damage that are too severe to be repaired. You may see our Mobile Tune Up and Repair professionals take the time to remove your flat from the rim and inspect the inside before repairing it, which means we’re just following good procedure.

Now some tires just can’t be repaired. A puncture may be too large to plug. Also, the puncture could be in a location that’s not safe to repair like in the sidewall or outer portion of the tread. So called run-flat tires should not be repaired because their design is such that internal damage can’t be detected by a visual inspection.

It is also important that repairs should only be done by a qualified tire specialist like the ones we have at Mobile Tune Up and Repair. You can buy self repair kits – save those for emergencies, like when you’re off-roading and need a quick fix so you can hobble back to civilization and get professional help. If you need to use a repair-in-a-can product, remember it’s a temporary measure only and your tire needs to be properly repaired as soon as possible.

Here are some other considerations: Repairing a flat may void your tire manufacturer’s warranty – just something to keep in mind. Also, if you repair a speed rated tire, you should not use it in any motorsports or operate it above legal speed limits. Your tire professional will repair your tire whenever it’s safe to do so and he’ll advise you when it’s better to replace it. So watch those curbs and keep the air – on the inside.
