The radiator keeps your car from overheating and so the mechanical parts don’t bind. So, how does it work?
The vehicle’s coolant constantly circulates between the engine and the radiator. The coolant is transferred the heat from the engine and is then cooled by the radiator, maintaining the proper temperature of the engine.
Schedule Radiator Repair
A radiator flush is recommended every two years, or when recommended, and should be checked every spring and fall before the weather gets too hot and too cold. Other parts of the cooling system that may need service includes:
Radiator Cap - When highly pressurized coolant enters the radiator, the radiator cap opens at the maximum pressure point, allowing heat and excess fluids to escape. The radiator cap should be replaced when it leaks or is unable to hold pressure.
Thermostat - The entire engine has a recommended temperature, which the thermostat helps regulate by maintaining the coolant temperature. An engine that overheats or has a heating problem could be a sign of a defective thermostat.
Water Pump - The water pump’s job is to pump the coolant throughout the cooling system, maintaining proper engine temperature. A broken water pump could lead to the engine overheating, causing expensive repairs and even engine replacement. The water pump is recommended to be inspected at each oil change. Replacement is necessary when there is a visible loss of coolant at the body drain, excess looseness at the water-pump shaft, or a rumbling noise in the pump- shaft bearings.
Radiator Hoses - The coolant travels through these hoses and should be checked periodically. They should be replaced when they become brittle, cracked or when they are leaking.
