Parts for your 2014 Subaru Impreza-Oil pump

2014 Subaru Impreza oil pump — purpose, servicing and replacement

Based on the Subaru Factory Service Manual for the FB20 engine (Lubrication section) and Subaru’s official service/parts catalogues, the 2014 Subaru Impreza is fitted with a crankshaft‑driven trochoid (gerotor) engine oil pump mounted at the front of the engine. So yes, the oil pump is absolutely relevant on this model.

The oil pump’s gig is simple but vital: draw oil from the sump through the pickup, pressurise it, and send it through galleries to the crank and rod bearings, camshafts, timing chains, and the AVCS system. Consistent oil pressure means less wear, quieter running, and better temperature control—especially handy for long Aussie and Kiwi drives and hot summer starts under the bonnet.

There’s no scheduled replacement for the pump in the logbook
