Parts for your 2018 Isuzu D-max-Oil pump

2018 Isuzu D‑MAX oil pump — what it does and how to look after it

Yes, the 2018 Isuzu D‑MAX absolutely uses an engine oil pump. Technical sources including the Isuzu D‑MAX (TFR/TFS) Workshop Manual for 2012–2019, the 4JJ1 engine service manual, and the Isuzu Electronic Parts Catalogue list a trochoid/gerotor‑type oil pump for the 3.0‑litre 4JJ1 diesel (and similarly for the 1.9 RZ4E in other markets). It’s a mechanically driven pump that feeds pressurised oil to bearings, cam lobes and the turbocharger—so it’s not optional kit
