The Head Gasket Explained

The head gasket seals the engine block to the cylinder head. It serves two purposes in providing a powerful seal that optimizes combustion pressure and preventing coolant fluid and motor oil from mixing. Head gasket damage can cause poor compression, fluid mixing, and performance problems. This is why the head gasket should be inspected for leaks and repaired if it loses integrity.

Head Gasket Maintenance

Head gaskets are durable but should be inspected routinely and serviced if damaged. Routine maintenance can be the difference between minor damage qualifying for repair versus extensive damage that we call a blown head gasket requiring a total replacement service. Knowing the warning signs of head gasket trouble and responding promptly with an inspection is a good way to prevent the worst consequences of a blown head gasket.

Warning Signs of Damaged Head Gaskets

Here are the telltale warning signs of head gasket trouble:

• Steam coming from under the hood
• Exhaust smoke is whiter
• Coolant found low without signs of leaking
• Bubbles in the radiator or coolant reservoir
• Rough engine idling
• Overheating engine
• Dashboard warning light

Head Gasket Repairs vs Replacement

Minor head gasket damage can be repaired with a specialized sealant. Extensive damage cannot be repaired and the full head gasket will require replacement service to fix. Our certified technicians know the head gasket, its specifications, and maintenance requirements inside and out. Be sure to get an inspection promptly if you notice any signs of head gasket problems as this can be the difference between getting repairs versus replacement service.
