Parts for your 2011 Honda Stream-Oil pump

2011 Honda Stream oil-pump: purpose, fitment, and service advice

Based on Honda technical literature and parts catalogues for the RN6–RN9 Honda Stream (with R18A 1.8L and R20A 2.0L i‑VTEC petrol engines), this model is fitted with an engine oil pump as part of its full‑pressure lubrication system. Factory service manuals and dealer EPC diagrams list the oil pump assembly and related components (pickup, relief system, seals), confirming it’s a standard, required part on the 2011 Honda Stream.

The oil pump’s job is straightforward but critical: it draws oil from the sump, pushes it through the filter, and feeds pressurised oil to bearings, camshafts, timing components and VTEC hardware. On these Honda engines, the pump is a compact, crankshaft/chain‑driven unit designed for reliable flow and low friction. Without healthy oil pressure, the engine won’t last long—so keeping the pump supplied with clean, correct‑grade oil is the real key.

There’s no routine replacement interval for the oil pump itself
