Parts for your 2024 Mitsubishi Triton-Oil pump

2024 Mitsubishi Triton oil pump — what it does and when to service it

Yes, the 2024 Mitsubishi Triton (all-new sixth-gen, 4N16 2.4‑litre turbo‑diesel) uses an engine‑driven oil pump. Technical sources confirm this: the Mitsubishi Motors 4N16 workshop manual (Lubrication section) diagrams a crankshaft‑driven internal trochoid oil pump, the Mitsubishi ASA/CAPS electronic parts catalogue lists a dedicated oil pump assembly for the 4N16, and Mitsubishi’s global technical brief for the new Triton cites upgraded lubrication capacity for the turbocharger and piston‑cooling jets—systems that rely on a pressurised oil pump.

On this Triton, the oil pump’s job is to pull oil from the sump and push it under pressure through the filter to bearings, camshafts, the turbo, and those piston jets. That steady pressure keeps friction and heat in check, helps the engine last the distance, and protects the turbo when it’s working hard towing or off‑road.

For most owners, “servicing the oil pump” really means looking after the oil system so the pump can do its thing. Stick to the owner’s manual service schedule—typically every 15,000 kilometres or 12 months in AU/NZ markets, and halve that if you’re doing lots of short trips, dusty work, heavy towing, or idling. Always use the specified low‑ash diesel engine oil (commonly 5W‑30 to ACEA C2/C3, or as per the handbook) and a quality filter. Keeping oil clean and at the right viscosity is the best insurance for pump health and stable oil pressure.

Actual oil pump replacement is uncommon and usually only on high‑kilometre engines, after oil starvation, or during timing/front cover work. It’s a front‑of‑engine job that needs proper tools and know‑how (sump, pickup, front cover access, sealing and priming). When it’s open, it’s smart to:

• Inspect and clean/replace the pickup screen and O‑rings.
• Check the pressure relief valve for sticking or scoring.
• Use correct sealant and torque, then verify pressure with a mechanical gauge.

Things that warrant diagnosis before bigger repairs include:

• Low oil pressure warning, flicker at hot idle, or slow pressure build on cold starts.
• Top‑end tapping, bottom‑end rumble, or new turbo noise after an oil change.
• Metallic glitter in drained oil or the filter.

If any of that pops up, stop driving and get a pressure test done. Often the fix is as simple as the right fresh oil and filter, if pressure stays low, a blocked pickup, relief valve issue, or a worn pump (or bearings) needs attention by a qualified technician.

Popular questions about 2024 Mitsubishi Triton oil pumps

Does the 2024 Triton actually have an oil pump?
Absolutely. The 4N16 diesel uses a crankshaft‑driven trochoid oil pump as part of its pressurised lubrication system. It’s integral to feeding the turbo, bearings, and piston‑cooling jets, as shown in the Mitsubishi service manual and parts catalogue for this engine.

How long should an oil pump last on a 4N16 Triton?
With correct oil and on‑time services, the pump typically lasts the life of the engine. Failures are rare and usually linked to contamination, sludge from extended intervals, or prior oil starvation. Keep up with 15,000 km/12‑month services (or shorter in severe use) and it should be trouble‑free.

What are the warning signs of a failing oil pump?
Watch for the low‑pressure light, rattly top‑end on cold start that doesn’t quickly quieten, hot‑idle pressure flicker, or new turbo noise. If you see metal in the oil or the light stays on, park it and have oil pressure checked with a mechanical gauge before driving further.
