Overheating engine: what to do

·5 min read

An overheating engine can cause expensive, permanent damage in minutes. Here's exactly what to do when your temperature gauge hits the red.

Immediate steps when your engine overheats

Turn off the air conditioning and turn the heater to maximum. Pull over safely and turn off the engine. Do NOT open the bonnet immediately — wait at least 15–20 minutes for pressure to subside.

Common causes of overheating

Low coolant level, faulty water pump, stuck thermostat, blocked radiator or a blown head gasket.

When to request a tow

If the engine doesn't restart normally after cooling, or if you see fluid leaking or steam continues after cooling, request a tow via FastAssist24.
