1988 Mitsubishi Pajero Head Gasket – What It Does and How to Look After It

A head gasket is absolutely relevant on the 1988 Mitsubishi Pajero. Technical references including the Mitsubishi Pajero/Montero Workshop Manual (1982–1991), the Mitsubishi 4D56 Engine Service Manual, the Mitsubishi ASA electronic parts catalogue, and the Haynes Pajero/Montero manual (1983–1996) all specify a cylinder head gasket and head-bolt torque sequence for the 4D56 2.5 diesel, 4G54 2.6 petrol, and 6G72 3.0 V6 engines used in 1988 models.

On these Pajeros, the head gasket sits between the cylinder head and the engine block, sealing three critical things at once: compression in the cylinders, engine coolant passages, and engine oil galleries. It has to put up with big thermal swings, high combustion pressure, and constant chemical exposure. When it’s doing its job, the engine runs smoothly, holds temperature, and keeps fluids where they belong.

Owners typically see trouble only after overheating, poor coolant maintenance, or detonation. Keeping the cooling system up to scratch is the best defence. That means fresh coolant at the recommended intervals, a healthy radiator and cap, a working thermostat, and a fan/viscous coupling that actually pulls air at idle. For belt-driven engines (4D56, 6G72), it’s a smart play to refresh the timing belt and water pump during a head-gasket job
