Cooling System Diagnosis

So, The cooling system diagnosis is composed of various parts: the radiator, pressure cap, fan, pump, thermostat, hoses and overflow tank. Also, The pump sends cooling fluid to the engine where it absorbs the engine’s heat.

So, A cooling system works by circulating liquid coolant through passages in the engine block and cylinder head(s). Also, As the coolant flows through these passages, heat is transferred from the engine components to the coolant. The heated coolant then makes its way through a rubber hose to the radiator in the front of the engine compartment.


Finally, As it flows through the thin tubes in the radiator, the hot liquid is cooled by the air flow entering the engine compartment through the grill in front of the vehicle. Once the fluid is cooled, it returns to the engine to absorb more heat. The water pump has the job of keeping the fluid circulating through the system when the engine is running.
