Parts for your 2006 Toyota Vitz|yaris-Head gasket

2006 Toyota Vitz/Yaris head gasket — what it is, what it does, and when to sort it

Based on factory and aftermarket technical references — including the Toyota Repair Manual for NCP90/91/93 models, Toyota’s Electronic Parts Catalogue for the 1NZ‑FE and 2SZ‑FE engines, and the Haynes Yaris (2005–2011) service manual — the 2006 Toyota Vitz/Yaris is fitted with a cylinder head gasket. It’s a multi‑layer steel (MLS) gasket that sits between the aluminium cylinder head and the engine block, sealing combustion, coolant and oil passages.

On this model, the head gasket’s job is to keep compression in the cylinders while preventing coolant and engine oil from mixing or leaking externally. It handles intense combustion pressures and the daily heat cycles of stop‑start city use common across Australia and New Zealand. The MLS design suits the aluminium head’s expansion behaviour, maintaining a reliable seal when the engine goes from cold morning starts to motorway temperatures.

For owners considering servicing of their 2006 Toyota Vitz/Yaris head gasket, think of it as preventative care around the gasket rather than the gasket itself — keep the cooling system healthy so the gasket never gets cooked. Overheating is the chief enemy
