The cooling system is responsible for maintaining engine temperature within safe range (80-95°C).

Cooling System Components:

Radiator:

Main heat exchanger

Cools liquid with ambient air

Keeping radiator fins clean is essential

Water Pump:

Circulates coolant in the system

Usually driven by belt

Failure causes overheating

Thermostat:

Regulates engine temperature

At low temperature closes radiator water path

Failure causes excessive heat or cold

Cooling Fan:

Passes air through radiator

Can be mechanical (belt-driven) or electric

Common Cooling System Problems:

Coolant leak

Thermostat failure

Clogged radiator

Water pump failure
