Cooling System Repair

What does a cooling system do?

A vehicle?s cooling system components consist of a radiator, water pump, heater core and hoses. The system keeps the engine from overheating by transferring this heat to the air. It also allows the engine to heat up as quickly as possible, and helps to keep the engine at a constant temperature.

How do I know if the cooling system is working properly?

If the engine temperature is too low, fuel economy will suffer, and if the temperature is too hot for too long, the engine will be damaged. Fortunately, most vehicles have temperature gages and warning lights. If the coolant is not properly maintained, the engine can overheat and damage the engine. A visual inspection of the system components may indicate whether a belt or hose is damaged. Other potential problems include a bad thermostat, engine fan, or internal or external leaks in the system.

What are my options?

The vehicle can either be taken to a local dealer or repair shop, or the owner can repair it. There are numerous automotive websites that explain how to repair or replace system components. Other sites advertise repair services, sell parts, and/or offer repair manuals or how-to books.
