Parts for your 1998 Nissan Navara-Head gasket

1998 Nissan Navara head gasket — what it does and when to sort it

Yes, a head gasket is absolutely relevant and fitted to the 1998 Nissan Navara. Technical references including the Nissan D22 Factory Service Manual (1997–2001, Engine Mechanical section), the Nissan TD27/QD32 Workshop Manuals, and the Nissan FAST parts catalogue list a cylinder head gasket for the KA24E petrol and the TD27/QD32 diesel engines used in AU/NZ market D22 Navaras of that era. Aftermarket manuals (e.g., Haynes/Nissan Pick-up 1998–2004) also cover head gasket replacement procedures for these engines.

On a ’98 Navara, the head gasket’s job is to seal the combustion chambers while keeping the engine oil and coolant flowing through their passages without mixing. It sits between the block and the cylinder head, dealing with big pressure swings, heat, and vibration every time the ute fires up and heads down the highway or across the paddock.

It’s not a scheduled “replace-by” service item
