Parts for your 2022 Mitsubishi Eclipse cross-Oil pump

2022 Mitsubishi Eclipse Cross oil pump — what it does and how to look after it

Yes, the 2022 Mitsubishi Eclipse Cross uses an engine oil pump. This is documented in Mitsubishi Motors’ workshop literature for Eclipse Cross (Group 12: Engine Lubrication) and supported by the Mitsubishi ASA/OEM parts catalogue, which lists an oil pump assembly for both the 1.5L MIVEC turbo petrol (4B40) and the 2.4L Atkinson-cycle petrol engine used in the Eclipse Cross PHEV. So the oil pump is absolutely relevant to this model.

On this vehicle, the oil pump is a positive-displacement unit (gerotor/trochoid style) driven off the crankshaft and housed in the front cover. Its job is to pull oil through the pickup and strainer, push it through the filter, then feed the crank, cams, timing gear, and turbo (on the 1.5T). Without proper oil pressure, bearings cop a hiding, the turbo can be starved, and the engine won’t last long.

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

• Change engine oil and filter on time (typically every 12 months/15,000 km in AU/NZ, or sooner if towing, lots of short trips, or dusty use). Use the specified low-viscosity oil grade (commonly 0W-20 meeting API SP/ILSAC requirements per your owner’s manual).
• Watch for warning signs: low oil pressure light, ticking on cold start, harsh chain/gear noise, rising engine temps, or a turbo whine on the 1.5T. Don’t keep driving if the pressure light comes on.
• If pressure looks crook, have a technician verify with a mechanical gauge at the engine’s gallery port per the service manual, and inspect the pickup strainer for silicone debris or sludge.
• Pump replacement is usually only needed after confirmed low pressure with clearances out of spec, visible scoring, metal contamination, or during an engine rebuild. The job typically involves sump removal, front cover work, new seals/O-rings, and correct sealant application.
• On reassembly, prime the pump with clean oil, fit a new pickup O-ring, and crank with ignition/fuel disabled to build pressure before first start.

Owners of the Eclipse Cross PHEV get the same message: it still has a conventional engine that relies on proper oil pressure, so the pump’s health is just as critical even if the petrol engine runs less of the time.

Popular questions

Does the 2022 Eclipse Cross (including PHEV) actually have an oil pump?
Yes. Mitsubishi’s service documentation for the Eclipse Cross lubrication system and the ASA parts catalogue both list an engine oil pump for the 1.5L turbo petrol and the 2.4L PHEV engine. It’s a crank-driven positive-displacement pump built into the engine’s front cover assembly.

What are the common signs the oil pump needs attention on a 2022 Eclipse Cross?
Red oil pressure warning light, tapping or rattling on start-up, hotter-than-normal operation, or turbo noise (on the 1.5T). Always confirm actual pressure with a mechanical gauge and rule out low oil level, a blocked pickup strainer, or bearing wear before blaming the pump itself.

Should the oil pump be replaced as preventative maintenance?
Not typically. With regular oil and filter changes and the correct spec oil, the factory pump lasts a very long time. Replacement is considered when low pressure is verified and internal wear or damage is found, or during an overhaul after contamination or major engine work.
