A head gasket leak can cause a lot of problems with your car.

The biggest problem caused by a leaking head gasket is the loss of coolant.

Whether the leak is external,

  • causing a water leak into your engine bay

Or internal,

  • causing coolant to be pulled into your combustion chamber

Losing coolant can lead to a dangerous situation in your vehicle.

A leaky head gasket is bad news for several reasons: Besides causing the engine to lose coolant and overheat, antifreeze entering the cylinder can wash away the oil that protects the rings and pistons against wear. Antifreeze in the crankcase can also dilute and contaminate the oil, which may lead to bearing wear and failure too.

All engines produce a small amount of visible steam in the exhaust when they are first started on a cold morning. If you see white smoke when the engine is running at normal temperature (and it is not below freezing outside), there could be coolant in the exhaust from a leaky head gasket. The exhaust may also have a sweet smell.

A low coolant level can lead to your engine overheating which can quickly cause a lot of damage.

Any number of things might have caused the head gasket to fail. One of the most common causes is engine overheating. If overheating was the cause of the head gasket failure, it’s important to figure out why the engine overheated so it doesn’t happen again.

So, If the water pump, radiator, hoses or engine is leaking coolant, the leaks have to be found and fixed. Otherwise, the head gasket may fail again if the engine is running hot.
