2004 Honda CR‑V Oil Pump — Purpose, Maintenance and Replacement

The 2004 Honda CR‑V absolutely uses an engine oil pump. Technical sources including the Honda CR‑V 2002–2004 Service Manual (Lubrication System — Oil Pump), the Honda Electronic Parts Catalogue for the K24A1 engine (oil pump assembly listed for this VIN range), and Honda Technical Information System service procedures all detail a chain‑driven, trochoid‑type oil pump integrated with the balance shaft module. So it’s a core part of the CR‑V’s 2.4‑litre K‑series engine, not an optional extra.

On this model, the oil pump’s job is to circulate pressurised oil through the crankshaft and cam bearings, timing chain, i‑VTEC components and other moving bits, keeping friction down and temperatures in check. The K24A1’s pump is driven off the crank via a chain and sits behind the front cover, with a pickup drawing oil from the sump. Because Honda tied the pump to a balance shaft assembly for smoothness, keeping oil clean and at the right level helps both the pump and the balancers live a long life.

There’s no routine replacement interval for the oil pump
