Parts for your 2012 Subaru Legacy-Oil pump

2012 Subaru Legacy oil pump — purpose, maintenance, and when to replace

Technical sources confirm the 2012 Subaru Legacy is fitted with an engine-driven oil pump across its available engines. The Subaru Factory Service Manual (2010–2014 Legacy/Outback, Engine Lubrication section) details oil pump removal, inspection, and installation for FB25, EJ-series turbo, and EZ36 engines, and the Subaru FAST electronic parts catalogue lists the oil pump assembly for these engines. General repair references (e.g., Haynes/Chilton for 2010–2019 Legacy/Outback) also cover pump checks and oil pressure diagnostics. So yes — this vehicle definitely uses an oil pump.

The oil pump on a 2012 Subaru Legacy keeps the engine alive by pushing pressurised oil through galleries to bearings, camshafts, and timing components. It’s mounted at the front of the engine and driven by the crankshaft, so pressure builds as revs rise. On EJ-series engines (where fitted), the pump is a bolt-on unit behind the timing belt pulley
