Q: Car overheating

asked by on

My Lexus is overheating.

Hello, a car that overheats should not be driven since the vehicle can incur further engine damage. On most modern cars, there can be many reasons for a car to overheat, such as mechanical reasons like a coolant leak, stuck thermostat or blown head gasket, to electrical reasons causing the engine cooling fan not working. You will need the aid of a mechanic who can monitor the engine as it warms up to diagnose your overheating issue.
