Engine Overheating
Overheating happens when engine temperature rises above its normal operating range.
What is Engine Overheating?
Common causes are low coolant, a stuck thermostat, a failed fan or a water pump fault. The temperature gauge or a warning light shows it. Steam from under the bonnet is a clear sign. If the gauge rises, switching the heater to maximum can remove some heat while you find a place to stop. Let the engine cool before checking coolant. White exhaust smoke, bubbles in the expansion tank or oil in the coolant after overheating can point to head gasket damage.
How it works
The cooling system cannot remove heat fast enough.
Why it matters for your car
Stop safely and switch off the engine to prevent damage. Continued driving can warp the cylinder head or blow the head gasket.
