What to do when your engine overheats
If an overheating warning appears, the gauge enters its warning zone or steam comes from under the bonnet, pull over as soon as it is safe and switch the engine off. Follow the owner’s manual. Leave the coolant cap closed while the engine is hot. Ask about vehicle collection if the car needs moving.
What to remember about the overheating
Was the car in traffic, cruising or climbing a hill? Tell us if it had been losing coolant, whether the warning came on suddenly and what happened afterwards. There is no need to restart it to see if the problem returns.
What might have caused it?
A leak, poor circulation or limited airflow can affect the cooling system. Overheating alone does not prove that the head gasket has failed.
How those details help
They guide the diagnostic assessment so we can look at what caused the overheating and whether the engine needs checking for damage.
