Parts for your 2024 Mitsubishi Eclipse cross-Oil pump

2024 Mitsubishi Eclipse Cross oil pump — what it does and how to look after it

Technical sources confirm the 2024 Mitsubishi Eclipse Cross is fitted with an engine oil pump. Mitsubishi’s workshop/service manuals for the Eclipse Cross (Lubrication section), the Mitsubishi Motors Electronic Parts Catalogue (ASA) listing an oil pump assembly for the 1.5‑litre turbo petrol (commonly referred to as 4B40) and the 2.4‑litre PHEV engine, and the Owner’s Manual reference to an engine oil pressure warning lamp all point to a pump‑driven, pressurised lubrication system on this model.

Day to day, the oil pump is the heartbeat of the Eclipse Cross’s engine. Driven off the crankshaft and housed in the front cover, it pulls oil from the sump and pushes it through the filter and galleries to crank and rod bearings, camshafts, timing components and the turbocharger on the 1.5T. Modern Mitsubishi units commonly use a gerotor/variable‑displacement style to trim parasitic losses at cruise while holding pressure when the driver asks for more. Without that constant flow, metal surfaces would scuff, bearings would fail and the turbo could seize in short order.

It’s not a routine replacement item. Caring for it is 90% about oil quality: follow the factory service intervals, use the specified viscosity and a quality filter, and don’t stretch changes just because a PHEV engine may run less often. After an overheat, sludge event or fuel dilution concern, get the oil and filter changed promptly and have a technician check oil pressure and the pick‑up screen under the bonnet.

If the pump ever needs replacing, it’s a proper workshop job. The front cover comes off, seals and O‑rings are renewed, the pump is packed/primed with clean oil, and the system is verified for pressure and leaks on restart. On the 1.5T, it’s smart to flush or replace the turbo oil feed and ensure the filter isn’t on bypass. Genuine parts or reputable OEM‑equivalent components, correct sealant on the front cover, and torque‑to‑spec are must‑dos. Skipping any of that can cost an engine.

• Watch for: oil pressure warning, rattly top end at cold start, VVT/turbo faults, metallic glitter in drained oil.
• Don’t drive with low oil pressure. Get it towed to avoid major damage.
• If tuned or worked hard in hot conditions, shorten oil change intervals and monitor pressure more closely.

Does the 2024 Mitsubishi Eclipse Cross have an oil pump?

Yes. Both the 1.5‑litre turbo petrol and the 2.4‑litre PHEV engines use a crankshaft‑driven oil pump as part of their pressurised lubrication systems. This is reflected in Mitsubishi service literature, the parts catalogue, and the Owner’s Manual oil pressure warning function.

How often should the oil pump be replaced?

There’s no scheduled replacement interval. The pump is designed to last the life of the engine when serviced with the correct oil and filter at the recommended kilometres/time. Replacement is only considered if there’s verified low oil pressure, internal wear, contamination damage or during a major engine rebuild.

What are the signs of a failing oil pump on an Eclipse Cross?

Low oil pressure warnings, top‑end ticking after start, VVT‑related fault codes, unexplained turbo issues (1.5T) or metallic debris in the oil are red flags. If any occur, stop driving and have it inspected—continuing to run can rapidly damage bearings and the turbo.
