How Long Can You Drive With a Blown Head Gasket?

Head gasket replacement is an expensive repair.

Drive as Little as Possible

See a trusted engine mechanic as soon as possible.

Depending on the degree of damage already sustained, you may be able to drive a short distance. If your vehicle still runs, you risk causing serious engine damage by driving it with a blown head gasket. Tow the car if possible.

Possible Short Trips

The radiator, water pump or thermostat could cause overheating problems.

Blown head gaskets display serious overheating. If you are experiencing repeated overheating problems, have your mechanic check for other possible causes before doing a major repair such as a head gasket replacement. If you can add water after overheating and the engine runs, a quick trip might get you home.

Bottom Line

If you must drive, watch the temperature gauge carefully.

Even if the vehicle will still drive, consider having it towed to the repair shop if you suspect a blown head gasket. Further driving can cause serious damages and costly repairs. Compare the cost of replacing the head gasket to the cost of replacing the engine.
