Q: My car overheats after 20 minutes

asked by on

My car overheats if I drive more than 20 minutes.

A: If you car is overheating after 20 minutes ...

If you car is overheating after 20 minutes of driving, I would first recommend checking to make sure that the cooling system is properly topped off with coolant. If your car is doing this continuously, I would recommend having a professional technician, such as one from YourMechanic, thoroughly inspect and diagnose the vehicle’s overheating issue before proceeding. This particular vehicle uses a GM Northstar Engine, which is notorious for overheating and having head gasket problems, so a professional opinion is highly recommended.
