Coolant System

Is your car running hot or overheating? Radiator cracked or leaking? The Omaha Auto Repair Cooling System experts at Gateway Auto Service Center are here to help.

Coolant Systems in vehicles play a crucial role in managing the engine's temperature and preventing it from overheating. This system includes the radiator, thermostat, water pump, coolant, and a series of hoses that circulate the coolant through the engine and back through the radiator.

The coolant absorbs heat from the engine and dissipates it through the radiator. Proper functioning of this system is vital for engine health, as it maintains optimal operating temperatures and prevents damage caused by excessive heat.

At Gateway Auto - Service & Collision Center, we offer comprehensive services for coolant systems, including inspections, maintenance, flushing, and refilling with the appropriate coolant.

Frequently asked questions

If it's a car, we'll fix it. If it's a question, we'll answer it.

Can a damaged radiator lead to engine problems?

Yes, a damaged radiator can lead to overheating, which in turn can cause engine damage, including warped cylinder heads and blown gaskets. Therefore, it is important to have your radiator inspected and repaired by a professional if you suspect it is cracked or leaking.

Why is my car overheating?

Overheating can be caused by various factors, including low coolant levels, a malfunctioning thermostat, a damaged radiator, cooling system leaks, or a faulty water pump. It is best to have an expert technician diagnose the root of the issue in order to prevent severe damage or safety risks while driving.

Can I prevent radiator issues through maintenance?

Regular cooling system maintenance, such as coolant flushes and inspections, can help identify potential radiator issues early and prevent major problems.

What happens if I drive with old coolant?

Driving with old coolant can lead to engine overheating, coolant leaks, and potential engine damage.

Can I just top off my coolant instead of getting a coolant flush?

Topping off your coolant is a temporary solution and should not be considered a replacement for a proper coolant flush. While topping off coolant temporarily may help maintain proper levels, it's still necessary to receive coolant flushes to rid contaminants, maintain coolant quality, prevent corrosion, increase component longevity and more.

What should I do if my car starts to overheat?

The best thing you can do is to kill the A/C, crank the heat (to pull heat away from the engine), and discontinue driving. Find a safe place to pull over and turn the vehicle off. This will help prevent damage to the engine. We advise against immediately trying to check under the hood as the coolant and engine may be dangerously hot and the fluid in the radiator can cause severe burns. The best thing to do is let your car cool down and have your car towed to your trusted auto repair shop if possible!
