Parts for your 2002 Mitsubishi Lancer-Oil pump

2002 Mitsubishi Lancer oil pump — purpose, care and when to replace

Based on the Mitsubishi Motors Lancer 2002 Service Manual (Lubrication), the Haynes Repair Manual for 2002–2007 Lancer, and the Mitsubishi OEM parts catalogue (ASA/CAPS), every 2002 Mitsubishi Lancer petrol engine (4G15, 4G18, 4G93, 4G94 and the 4G63T in Evolution models) is fitted with a crankshaft-driven gerotor oil pump integrated into the front (timing) case. So yes, the oil pump is absolutely relevant to this model.

On a 2002 Lancer, the oil pump’s job is to pull oil from the sump, pressurise it, and feed it through galleries to crank and rod bearings, camshafts, balance shafts where fitted, and—on Evolution models—the turbocharger. That steady flow keeps friction down, carries away heat, and flushes fine debris into the filter. Without solid oil pressure, the engine quickly cops wear it can’t recover from.

It’s not a routine replace-at-intervals part
