Parts for your 2001 Nissan Serena-Head gasket

2001 Nissan Serena head gasket — what it does and how to look after it

Yes, the 2001 Nissan Serena uses a head gasket. This is confirmed in Nissan’s C24 Serena Factory Service Manual (Engine Mechanical, EM), along with the QR20DE and YD22DDTi engine service manuals, which specify the cylinder head gasket, torque sequence and bolt replacement. Nissan’s FAST parts catalogue also lists head gasket part numbers for the C24’s petrol (QR20DE) and turbo-diesel (YD22DDTi) engines.

On this Serena, the head gasket sits between the cylinder head and engine block, sealing combustion pressure while keeping coolant and oil in their own lanes. It’s a multi-layer steel (MLS) design on both QR20DE petrol and YD22DDTi diesel variants, chosen for reliable sealing under thermal cycling. When it’s healthy, the engine holds strong compression, runs cool and dry, and delivers smooth kilometres under the bonnet.

There’s no routine “replacement interval” for a head gasket
