2019 Subaru Impreza Oil Pump — What It Does and How To Look After It

Technical sources confirm the 2019 Subaru Impreza absolutely uses an oil pump. The Subaru Factory Service Manual (FB20 engine, Lubrication section) details a crankshaft-driven, trochoid-type oil pump integrated into the front timing chain cover, and Subaru’s genuine parts catalogue lists an “Oil Pump Assembly” for this model. That makes the oil pump very much relevant to this vehicle.

On the 2019 Impreza, the oil pump’s job is to pull oil from the sump, pressurise it, and push it through the galleries to critical components like the crankshaft and camshafts, and to support the variable valve timing system. Because it’s driven directly by the crank, it reacts instantly to engine speed, maintaining stable pressure across the rev range. Without it, bearings would run dry, cams would scuff, and the engine would quickly cry enough.

This pump isn’t a routine “replace-at-X-kilometres” item
