Parts for your 2021 Lexus Is-Oil pump

2021 Lexus IS oil pump — what it does and how to look after it

Yes, the 2021 Lexus IS absolutely uses an engine oil pump. Factory technical sources such as the Lexus Technical Information System (TIS) repair manual for the 2021 IS and the Toyota/Lexus Electronic Parts Catalog list an engine oil pump assembly for the model’s engines (including the 2.0‑litre turbo 8AR‑FTS in the IS300 RWD and the 3.5‑litre V6 2GR series in IS300 AWD/IS350). Those documents include oil pump diagrams, specs and service procedures, confirming the pump is a standard, chain‑driven internal component on these engines.

Under the bonnet, the oil pump’s job is to pull oil from the sump and send it under pressure through galleries to bearings, camshafts and timing chains, and to feed systems like VVT‑i. On the 8AR‑FTS turbo engine, it also ensures the turbocharger’s bearings stay properly lubricated and cooled. Without steady oil pressure, wear skyrockets, temperatures climb and serious damage can happen in short order.

While the oil pump itself isn’t a routine replacement item, regular servicing keeps it happy for the long haul:

• Use the correct oil grade shown on the filler cap/owner’s manual (commonly 0W‑20 in ANZ markets) and a quality filter.
• Stick to Lexus service intervals (typically 10,000–15,000 km or 12 months, depending on conditions).
• Avoid extended oil change blowouts
