2017 Nissan Pathfinder head gasket: fitted, purpose, and servicing tips

Technical references including Nissan’s 2017 Pathfinder (R52) Factory Service Manual (Engine Mechanical – Cylinder Head), the Nissan OEM parts catalogue, and major gasket manufacturers’ catalogues (Mahle, Victor Reinz, Fel‑Pro) all list cylinder head gaskets for the 3.5‑litre VQ35DD V6 used in this model. That confirms the 2017 Pathfinder does use head gaskets—multi‑layer steel (MLS) units—one for each cylinder bank.

On this Pathfinder, the head gaskets sit between the aluminium cylinder heads and the aluminium engine block. Their job is to seal three things at once: high‑pressure combustion in each cylinder, engine oil passages, and coolant galleries. The MLS construction copes with heat cycles, pressure spikes, and slight movement between the head and block, keeping compression up and fluids where they belong.

There’s no scheduled replacement interval for head gaskets
