2006 Honda Stream Oil Pump: Purpose, Care, and When to Replace

The 2006 Honda Stream does use an oil pump. Honda’s Factory Service Manual (FSM) for the RN-series Stream and the Honda Electronic Parts Catalogue both list a crankshaft-driven gerotor oil pump in the engine’s lubrication system. Depending on trim and market, the 2006 Stream ran D17A (1.7L), K20A (2.0L) or R18A (1.8L) petrol engines, each fitted with an internal oil pump housed at the front of the block. So the oil pump is absolutely relevant to servicing and reliability on this model.

For the Stream, the oil pump’s job is simple but critical: it pulls oil from the sump through the pickup and pushes it under pressure through galleries to the crank, rods, pistons, camshafts and VTEC hardware. A steady supply of pressurised oil keeps friction low, manages heat, and prevents metal-to-metal contact that can quickly wreck a healthy engine. Honda’s gerotor design is compact, efficient, and designed to maintain stable pressure across the rev range, which is key for daily driving and those longer weekend runs.

As for maintenance, oil pumps aren’t a scheduled “every-X-kilometres” replacement item. They usually last the life of the engine if oil changes are done on time with the correct spec oil and filters. That said, high kilometres, sludge from stretched service intervals, or debris from previous engine wear can accelerate pump wear. Any low oil pressure warning, rumbling from the bottom end, or persistent VTEC engagement faults under load should prompt a proper oil pressure test and inspection of the pickup screen.

• Warning signs: oil pressure light flicker at hot idle, top-end ticking, delayed VTEC engagement, metallic debris in the sump.
• Good habits: quality 5W-30 (or market-specified grade), timely filter changes, and checking for leaks and consumption between services.

Replacement is a bit of a mission and best left to a competent workshop: the front cover and sump need to come off, the pickup and O-ring must be renewed, and HondaBond-style sealant applied correctly to avoid future leaks. Always use an OE or top-tier pump, replace the relief valve if it’s suspect, clean the pickup, and prime the new pump with fresh oil. Torque values, sealant paths and timing alignment details are all set out in Honda’s FSM—following those keeps the Stream happy and oil pressure rock solid.

Does the 2006 Honda Stream have an oil pump?

Yes. Honda’s factory manuals and parts catalogues show a crankshaft-driven gerotor oil pump fitted to the RN-series Stream engines (D17A, K20A, R18A). It sits in the front cover and feeds the entire lubrication circuit.

When should the oil pump be replaced on a 2006 Honda Stream?

There’s no fixed kilometre interval. Replace it if verified low oil pressure is present, if the pickup is contaminated, during a major rebuild, or when there’s evidence of internal wear. Many last well past 250,000 km with correct servicing.

What else should be replaced with the pump?

Always renew the pickup O-ring, front cover seals, sump gasket/sealant, and consider the pressure relief valve. It’s smart to flush the sump, check the pickup screen, and refill with the correct oil grade and a quality filter.
