Parts for your 2001 Mitsubishi Pajero-Oil pump

2001 Mitsubishi Pajero oil pump — what it is and how to look after it

Is an oil pump relevant for a 2001 Mitsubishi Pajero? Yes. Technical sources confirm that both main engines fitted to the 2001 Pajero— the 3.5‑litre 6G74 V6 petrol and the 3.2‑litre 4M41 DI‑D diesel — use a crankshaft‑driven, internal oil pump integrated into the front timing case. This is outlined in the Mitsubishi Motors NM/NP Pajero workshop manual (Engine—Lubrication section) and the Mitsubishi ASA parts catalogue listings for the oil pump assemblies for 6G74 and 4M41 engines. So, the oil pump is absolutely used and is critical to engine health on this model.

The Pajero’s oil pump does the heavy lifting that keeps the engine alive. Driven off the crank, the gerotor/gear‑type pump pulls oil through the pickup strainer, pressurises it, and feeds bearings, camshafts, lifters, and the turbo on DI‑D models. That pressurised film of oil is what prevents metal‑to‑metal contact, especially on cold starts and long climbs with a loaded trailer. Without a healthy pump and clean oil, wear ramps up fast.

While the pump itself isn’t a scheduled replacement item, good servicing keeps it happy. Stick with quality oil that meets the correct spec and change it on time
