Engine overheating - what to check
If the temperature gauge climbs above normal, there's usually one specific part in the cooling system that's stopped working.
Possible causes
- A stuck thermostat - the engine overheats even at steady speeds
- A failed water pump - coolant stops circulating
- A radiator leak or blockage - not enough coolant left in the system
Overheating isn't something to put off - driving on with a hot engine can turn into a far more expensive repair.
