Parts for your 2004 Nissan Pulsar-Head gasket

2004 Nissan Pulsar head gasket — what it does and how to look after it

The 2004 Nissan Pulsar (N16 series) absolutely uses a head gasket. This is confirmed by the Nissan Pulsar N16 Factory Service Manual (Engine Mechanical section), which includes procedures for cylinder head and gasket service, and by Nissan FAST parts catalogues listing the cylinder head gasket for common N16 engines like the QG16DE and QG18DE. Independent workshop data sets (e.g., Autodata and Haynes coverage for Almera/Pulsar N16) also document head gasket specifications and torque sequences for these engines.

On this Pulsar, the head gasket sits between the engine block and the cylinder head. Its main job is to seal the combustion chambers so the engine keeps strong compression, while also keeping engine oil and coolant in their own passages without mixing. The factory gasket is a multi-layer steel (MLS) type designed to cope with heat cycles, pressure, and the alloy head’s expansion.

Head gaskets aren’t a routine “service item” to replace on time
