Parts for your 2005 Toyota Ractis-Oil pump

2005 Toyota Ractis Oil Pump – Purpose, Care and When to Replace

Yes, the 2005 Toyota Ractis is fitted with an engine oil pump. This applies to the common NCP100/NCP105 models running the 1NZ-FE 1.5‑litre petrol engine (and the smaller 1KR-FE where fitted). Toyota’s service literature (Toyota TIS Repair Manual – Engine/1NZ‑FE, Lubrication System: Oil Pump) and New Car Features documentation describe a crankshaft-driven, internal-gear (trochoid) oil pump integrated into the timing chain cover. It’s a normal, essential component on these engines and is required to maintain oil pressure and protect bearings, cams and the timing chain.

On the Ractis, the oil pump’s job is to draw oil from the sump, push it through the filter and galleries, and keep a steady pressure so every moving bit under the bonnet is lubricated. The 1NZ‑FE’s pump is compact and efficient, using that trochoid gearset design you’ll see across a lot of Toyota small-capacity engines. Without it, the oil warning lamp would be the least of anyone’s worries—bearing damage can happen in seconds.

There’s no set replacement interval for the oil pump in Toyota schedules
