Parts for your 2019 Mitsubishi Outlander-Oil pump

2019 Mitsubishi Outlander oil pump — what it does and how to look after it

Yes, the 2019 Mitsubishi Outlander uses an engine oil pump. This is confirmed by Mitsubishi’s Workshop/Service Manuals for the GF/GP-series Outlander (Engine Lubrication section) and the Mitsubishi ASA electronic parts catalogue, which both list an oil pump assembly for the 2.0L and 2.4L 4B1-series petrol engines, the PHEV’s Atkinson-cycle petrol engine, and the 3.0L 6B31 V6 used in some markets. These sources describe a crankshaft-driven trochoid/gerotor-style pump integrated into the front cover, supplying pressurised oil to bearings, camshafts and timing components.

The oil pump’s whole job is to push the right amount of oil, at the right pressure, through the Outlander’s engine so everything stays lubricated and cool under the bonnet. Without it, metal parts would scuff, seize and cost a small fortune to put right. On the 2019 models, the pump is a robust, crank-driven unit designed to last the life of the engine when looked after with proper servicing.

As part of regular servicing, the smartest way to care for the oil pump is indirect: keep clean, correct-spec engine oil flowing. Use the grade recommended for your exact engine (common specs are 0W-20 or 5W-30, depending on variant and climate) and stick to the service intervals in the owner’s handbook. A quality filter and timely oil changes prevent sludge and varnish that can starve the pump pickup or wear the pump’s internals.

Oil pumps aren’t typically a scheduled replacement item on the Outlander. Replacement is considered when there’s evidence of low oil pressure or internal wear, often during an engine rebuild or timing cover-off repairs. If the oil pressure warning light flicks on, don’t keep driving—shut it down and get it checked.

• Common warning signs: oil pressure light on, top-end ticking on cold start that doesn’t clear, timing chain rattle, metal debris in the oil, or fault codes from the oil pressure circuit.
• If replacement is required: use OEM-quality parts, renew the pickup O-ring and seals, check the pickup screen for sludge, verify clearances, and prime the pump with clean oil before first start. After reassembly, confirm pressure with a mechanical gauge.
• Good habits: keep to service intervals, avoid extended idling on old oil, and use the right viscosity for local temps in Australia or New Zealand.

Popular questions

Does the 2019 Outlander actually have an oil pump, including the PHEV?

It does. All 2019 Outlander petrol engines—2.0L/2.4L four-cylinders, the 3.0L V6 where fitted, and the PHEV’s petrol engine—use a crank-driven trochoid/gerotor oil pump mounted in the front cover. This is documented in Mitsubishi’s Service Manual lubrication section and the ASA parts catalogue listings.

How long should the oil pump last on a 2019 Outlander?

With proper servicing, the pump is designed to last the life of the engine. Most replacements happen only if there’s confirmed low oil pressure, a major internal failure, or during an engine rebuild. Clean oil and a fresh filter are the best insurance for long pump life.

What should be checked when replacing the oil pump?

Inspect and clean the pickup screen, renew seals and the pickup O-ring, check bearing and pump clearances, verify the pressure relief valve moves freely, and always prime the pump. After start-up, confirm oil pressure with a gauge and check for leaks around the front cover.
