What are the Symptoms of a Blown Head Gasket?

Regular vehicle maintenance is essential for keeping your car functioning for many years. A blown head gasket is an issue that most car owners hope to avoid because a blown head gasket can be lengthy to repair. The good news is, this issue can be avoided with good vehicle maintenance and care. Here's what you need to know about blown head gaskets and the signs of a blown head gasket.

What is a Head Gasket?

A head gasket is an essential component of modern engines. This engine part prevents the coolant, oil, and combustion gasses in your vehicle from leaking. The head gasket is located between the cylinder head and engine block.

Signs of a Blown Head Gasket

Here are some of the common signs you have a blown head gasket.

Bubbles in the Radiator

A few bubbles in the radiator are normal, but if the bubbling persists, usually after 20 minutes of idling, a blown head gasket may be the culprit. If the head gasket is the problem, combustion gasses have entered the cooling system, causing bubbling in the radiator.

White Exhaust Smoke

Unless you're driving a vehicle that uses diesel, your car's exhaust should be clear. White exhaust smoke is an indication there is moisture in the combustion chamber. If you notice white exhaust smoke coming from your vehicle's tailpipe, a blown head gasket may be causing the problem.

Difficulty Starting

If you're having difficulty starting your car, or you notice your vehicle runs rough, a blown head gasket may be the cause. When coolant floods one or multiple chamber cylinders, air or combustion fuel can't ignite. In order for combustion to occur, all cylinders must remain dry.

An Overheating Engine

An overheating engine is never a good thing. A blown head gasket can cause the engine to overheat, but it can also be an indication you have a blown head gasket. Exhaust gases are extremely hot, and when these gasses enter the car's cooling system, the coolant will quickly heat up, causing the engine to overheat.
