Cooling System Diagnosis – Keeping The Engine An Efficient Temperature
The cooling system is composed of various parts: the radiator, pressure cap, fan, pump, thermostat, hoses and overflow tank. The pump sends cooling fluid to the engine where it absorbs the engine’s heat.
After exiting the engine, it runs by a thermostat. If the cooling fluid is below the maximum temperature, the thermostat stays closed and the fluid is re-routed back to the pump.
Cooling System Diagnosis-However, if the fluid is overheated, the thermostat valve opens, routing the fluid through a radiator first. The radiator cools the fluid by releasing its heat to the air before returning it to the pump.
