1995 Mitsubishi Pajero Head Gasket — What It Does and When to Sort It

Based on technical sources including the Mitsubishi Pajero/Montero 1991–1999 Workshop Manual, the Mitsubishi Engine Overhaul Manuals for 4M40 (2.8 TD), 4D56 (2.5 TD) and 6G72 (3.0 V6), plus the Mitsubishi ASA/EPC parts catalogue, the 1995 Mitsubishi Pajero absolutely uses a cylinder head gasket. These factory references detail head-gasket specifications, torque sequences and replacement procedures for the listed engines, confirming the part is fitted and serviceable on this model year.

The head gasket on a ’95 Pajero sits between the cylinder head and engine block, sealing combustion pressure while keeping oil and coolant in their own lanes. Whether the engine is a diesel 4M40/4D56 or the petrol 6G72 V6, the gasket works under big thermal swings and clamping loads. Many Pajeros of this era run multi-layer steel (MLS) or high-spec composite gaskets designed to handle boost (diesels) and long-distance touring. Correct surface finish, bolt torque and cooling-system health all matter to keep that seal happy.

• Typical warning signs of trouble: persistent overheating, pressurised hoses from cold, sweet-smelling white exhaust smoke, coolant loss with no external leak, milky oil on the dipstick or filler cap, rough cold starts, or bubbles in the radiator/expansion bottle.

As part of sensible servicing, keeping the cooling system in top nick helps the head gasket live a long life. Fresh coolant (every 2–4 years), a healthy radiator, a good cap, proper bleeding, and a working thermostat and viscous fan/clutch are key. Avoid towing or dune work with a marginal cooling system—heat is the head gasket’s worst enemy.

If replacement is on the cards, a workshop should check the head and block for flatness and cracks, and clean mating surfaces correctly. Head bolts are often torque-to-yield, so new bolts (or studs) are strongly recommended. Follow the exact factory torque/angle sequence. Diesel owners should ensure the correct gasket thickness is selected (often identified by notches/holes on the gasket)—that choice is based on piston protrusion. On 6G72 and 4D56 engines, it’s smart to do the timing belt, tensioners and water pump while the front is apart
