Head Gasket Failure Symptoms

Head gaskets seal the cylinders of the engine in your car, and can fail for a variety of reasons. From overheating to cracks in the gasket, symptoms of gasket failure can give indicators as to the condition of your head gaskets.

Head Gasket Leaks

Head gasket leaks are the hardest to diagnose, especially if they are small. Lost or leaking engine coolant can often result in leaks, a strong indicator of head gasket failure.

Heat Problems

Lost or leaking coolant can cause heating issues, such as a lack of heat or the heat of the engine fluctuating oddly. The idle may fluctuate as well, another symptom.

Severe Cases

Drastic cases of head gasket failure are more obvious, such as white steam coming from the tailpipe in the morning and the odor of burning coolant. The cylinders of the engine might also flood with coolant, preventing the car from starting.

Leaking Fluids

Fluids may leak from a blown head gasket as well, such as black oil pooling under the car. Leaking red transmission fluid can also be a strong indicator.

Bubbles in the Coolant

If the engine is running, remove the radiator cap and look for bubbles in the coolant. Bubbles may indicate either head gasket failure or cracks in the cylinder heads or cylinder walls.
