2006 Mitsubishi Pajero Thermostat Housing: What It Does and When To Replace It

Based on Mitsubishi Motors’ workshop manual (Cooling System, Group 14) and the Mitsubishi ASA electronic parts catalogue for the 2006 Pajero/Montero/Shogun, every 2006 Pajero engine variant (including the 3.2 Di-D 4M41 and the 3.8 V6 6G75, with market-dependent 3.5 V6 options) is fitted with a thermostat and a dedicated thermostat housing, often listed as the water outlet. Aftermarket technical guides and OEM service literature alike depict the housing as the mounting point for the thermostat and hose connections, confirming it is absolutely relevant on this model.

On the 2006 Pajero, the thermostat housing does more than just hold the thermostat. It forms a sealed junction between the engine and cooling circuit, directs coolant flow when the thermostat opens, and commonly carries a bleed point or temperature sensor boss. In simple terms, it helps the engine warm up quickly, then keeps temps steady under load, towing, or off-road work—spot on for Aussie and Kiwi conditions.

Servicing-wise, the housing is a known wear point over time. Alloy versions can pit or corrode at the gasket face
