Parts for your 2006 Toyota Kluger-Head gasket

2006 Toyota Kluger head gasket — what it does and how to look after it

Based on Toyota’s Factory Service Manual for the 2006 Kluger/Highlander (covering the 2AZ‑FE 2.4‑litre and 3MZ‑FE 3.3‑litre petrol engines) and Toyota’s Electronic Parts Catalogue, this vehicle is fitted with a cylinder head gasket. The manuals specify the gasket, the head‑bolt torque sequence, and the replacement procedure, so a head gasket is absolutely relevant on a 2006 Toyota Kluger.

The head gasket’s job is straightforward but critical: it seals the combustion chambers while keeping engine oil and coolant in their own passages between the alloy cylinder head and engine block. On the Kluger, it’s a multi‑layer steel (MLS) design engineered to handle high combustion pressures and thermal cycling. When it’s healthy, you get proper compression, stable temps, and clean oil and coolant. When it’s not, you can see overheating, misfires, milky oil, or white exhaust smoke.

It’s not a routine service item, but the way the car is maintained has a big say in how long the gasket lasts. Keeping the cooling system in top nick helps massively—use Toyota Super Long Life Coolant, replace it at the recommended intervals, and make sure the radiator, water pump, thermostat, and fans are doing their thing. Avoid overheating at all costs
