Further testing will be done, and a machine shop will try to confirm whether the head gasket is the problem. This often involves pressure testing the cooling system and performing combustion leak tests.

How is a Head Gasket Replaced?

Replacing a head gasket is a labor-intensive process and requires disassembly of several under-hood parts before even reaching the engine. Then, parts of the engine will be taken apart in order to inspect and clean the areas touching the head gasket, and to replace the failed gasket. Then everything must be put back together. This process will take several days, typically. If any of the removed components are found to be worn or failing, it may be best to replace them at this time, as well.

Step-by-Step Replacement Procedure (Simplified):

1. Cooling System Drained: All coolant is removed from the system.
2. Disconnection of Components: Various hoses, electrical connectors, intake manifold, exhaust manifold, timing components, and other engine accessories are disconnected and removed to gain access to the cylinder heads.
3. Cylinder Head Removal: The cylinder heads are carefully unbolted and lifted from the engine block.
4. Inspection and Machining: The cylinder heads and the mating surfaces of the engine block are thoroughly cleaned. The cylinder heads are typically sent to a machine shop to be checked for flatness (warpage) and resurfaced if necessary.
5. New Head Gasket Installation: A new, high-quality head gasket is installed between the cylinder head and the engine block.
6. Reassembly: All components are reassembled in reverse order, ensuring all bolts are torqued to the manufacturer's specifications.
7. Refilling and Testing: The cooling system is refilled with the correct coolant mixture, and the engine is started and monitored for leaks and proper operation.
