Belts
A fan belt, also known as a drive belt, is a belt connecting your car's engine to the front mounted accessories. The fan belt rotates the water pump and engine fan, which maintains a cool environment for the engine and its components. Sooner or later, your vehicle's fan belts will dry out and crack. When you are ready for a replacement you can count on 4 L&A Auto Repair for all your vehicle's repair needs.

You not only have to get the belts replaced with quality ones but you should have the work done by experts. To have the belts replaced by auto cooling and heating experts - and get your car driving right - visit 4 L&A Auto Repair today. The mechanics at 4 L&A Auto Repair will thoroughly inspect your car's belts; replace all worn belts; and adjust the installed belts.

Coolant System Flush
A car's coolant system transfers excess heat from one part of the engine and finally loses it through the radiator fins. With time, the coolant becomes old and dirty. The old coolant will negatively impact the system's performance. To make sure the system is working effectively, consider having a regular coolant system flush. A coolant flush is basic maintenance for your car's cooling system. Call 713-263-9082 or visit 4 L&A Auto Repair in Houston, TX 77055 for all your coolant system flush and fill needs.

Hoses
Hoses transfer coolant and antifreeze throughout the engine's cooling system (including the radiator). Sooner or later, your vehicle's hoses will dry out and crack. When you are ready for a replacement you can count on 4 L&A Auto Repair for all your vehicle's repair needs.

You not only have to get the hoses replaced with quality ones but you should have the work done by experts. To have the hoses replaced by auto cooling and heating experts - and get your car driving right - visit 4 L&A Auto Repair today. The mechanics at 4 L&A Auto Repair will thoroughly inspect your car's hoses; replace all worn hoses; and adjust the installed hoses.

Radiator Flush
A radiator is the part of your vehicle that keeps the engine cool and protects it from excessive heating. To be cool, the radiator needs to remain clean - always. With time, sludge, rust and other solid deposits build up inside your car's radiator. These make the cooling system become clogged and less effective. This in effect hurts your vehicle's performance. A regular radiator flush is enough to keep the system in shape. For this reason, make radiator flushing a part of your routine car maintenance schedule. For all your radiator flush needs, call 713-263-9082 or visit 4 L&A Auto Repair today.

Radiators
Radiators are heat exchangers for cooling your car's internal combustion engine. A radiator cools the engine by circulating an engine coolant through the engine block - it then loses the heat to the atmosphere through radiation. A radiator has a set of tubes through which the engine coolant flows. Fins surround these tubes. When the radiator fails, the excess heat produced by the engine could damage the engine components. To prevent this from happening, have your radiator serviced regularly. To have your radiator needs handled by experts, visit 4 L&A Auto Repair today.

Radiator Questions and Answers

Q: When should the radiator in my car be replaced?

Often, radiators will last for the entire life of a car. On average a radiator lasts 8 to 10 years. However, there are a few factors that can reduce a radiator's working life such as improper maintenance, driving habits and environmental conditions.

Q: When replacing a radiator what else should be replaced?

If you replace your radiator you may need to replace three other parts as well - the thermostat, water pump and heater core. An auto repair professional at 4 L&A Auto Repair will let you know what other parts need to be replaced.

Q: What does radiator service include?

A: Radiator service starts with draining the system. Then we flush the radiator and engine block, inspecting all hoses to make sure they're not cracked. Next we refill the radiator with fresh coolant and finish by pressure testing the radiator cap and cooling system.

Q: Why is my car engine overheating?

A: The most common reason a car overheats is a lack of coolant or a coolant leak. However, if you have an older vehicle, it may also indicate that it is time to replace your radiator, thermostat, water pump or heater core. If it continues to be a problem that you can't fix, your best bet is to bring it to our shop in Houston.

Coolant Questions and Answers

Q: When is the coolant temperature too high?

The engine coolant is overheating if it's around 240 to 250 degrees. When the coolant gets this hot a light on your dashboard will come on to alert you. Pull over and turn your car off. The coolant is very hot and under extreme pressure. Do not attempt to remove the radiator cap until the car has cooled.

Q: Why is my coolant light on and what should I do?

A: If the dashboard light is red, indicating your car is overheating then you should pull over as soon as it is safe to do so and switch off the engine. If the coolant level is low or there is another problem with your cooling system, you could cause serious damage by continuing to drive.

Q: Why is my coolant leaking?

A: Corrosion within the radiator is the leading cause of a coolant leak. As the radiator tubes get older and weaker, sediment or debris collects inside and causes a leak. The sealing gasket between the tank and the radiator can also wear out, and lead to a leak.

Q: When should I do a coolant flush?

A: Your vehicle's owner's manual will recommend getting the coolant flushed about every 30,000 miles or three to five years, whichever comes first. Make sure to consult your owner's manual as some outline a more specific interval depending on the vehicle's make and model and your driving habits.

Q: How do I know what coolant I should use?

A: Your car's owner's manual provides a wealth of information. Follow the recommendations in your car's owner's manual to the letter unless otherwise recommended by the manufacturer or auto repair professionals. It will tell you what type of coolant is best to use in your vehicle. If you don't have a copy of your owner's manual, you can most likely find the information you need on the manufacturer's website.
