What It Does & How It Helps

The head gasket seals combustion pressure, coolant and oil between the block and cylinder head — the hardest-working seal in the engine. Under the extreme cylinder pressures of a turbo diesel it can fail and let coolant and combustion gases cross over, producing overheating, white exhaust, coolant loss and oil/coolant intermixing. A fresh, correct-thickness head gasket set restores a proper combustion and cooling seal and is the foundation of any head job or rebuild. Fresh head studs or bolts are strongly recommended alongside it.
