Parts for your 2006 Nissan Maxima-Head gasket

2006 Nissan Maxima head gasket — what it does and when to sort it

Yes, the 2006 Nissan Maxima uses a head gasket. The car runs the VQ35DE 3.5‑litre V6, and the Nissan Factory Service Manual (2006 Maxima, Engine Mechanical—Cylinder Head section) details removal and installation of the cylinder head gasket. Nissan parts catalogues for this model year also list the head gasket as a service part, and major technical catalogues carry complete head set kits for the VQ35DE. So, it’s absolutely a relevant component on this Maxima.

The head gasket’s job is to seal the combustion chambers and keep engine oil and coolant in their proper passages between the alloy cylinder heads and the aluminium block. On the VQ35DE it’s a multi‑layer steel (MLS) gasket designed to handle heat cycles and the higher cylinder pressures of a modern V6. When it’s healthy, there’s no cross‑leak of fluids, no compression loss, and the engine runs sweet as.

It’s not a routine service item
