Cooling system and coolant leaks
Overheating, coolant leaks and heater problems: inspection of the radiator, hoses, water pump, thermostat and cooling fans.
What this covers
The cooling system holds the engine at a steady temperature. Coolant flows through the engine and radiator, a pump keeps it moving, a thermostat controls the flow and fans pull air through the radiator when the car is slow.
A leak or a failed part can make the engine overheat, and overheating can damage the engine. Stopping early costs less than driving on.
How the problem is found
Coolant leaks often show only when the system is hot and under pressure. A pressure test holds the system at operating pressure so drips can be found with the engine off.
Never open the radiator or reservoir cap on a hot engine. The coolant is under pressure and can spray.
