Parts for your 2006 Toyota Highlander-Manifold gasket

2006 Toyota Highlander (Kluger) manifold gasket — purpose, servicing tips, and when to replace

Yes, a manifold gasket is fitted to the 2006 Toyota Highlander (Kluger). Toyota’s Factory Service Manual (TIS) for both engines offered that year—the 2.4L 2AZ-FE and 3.3L 3MZ-FE—details intake and exhaust manifold gaskets, including removal, installation and torque specs. The Toyota Electronic Parts Catalog (EPC) also lists the intake manifold gasket (and upper plenum gaskets on the V6) plus the exhaust manifold gasket as serviceable parts for this model. So it’s very much a relevant item on this vehicle.

On this Highlander/Kluger, the manifold gasket’s job is simple but critical. On the intake side, it seals the manifold to the cylinder head (and on the V6, the upper plenum to the lower manifold), keeping unmetered air out so the engine runs smoothly and fuel trims stay happy. On the exhaust side, it keeps hot gases sealed in the manifold, protecting nearby components, preventing that annoying ticking on cold start, and ensuring the oxygen sensors get clean, accurate readings.

When it’s time for servicing, manifold gaskets don’t have a fixed replacement interval
