Parts for your 2006 Toyota Caldina-Head gasket

2006 Toyota Caldina head gasket — what it does and when to service it

Technical sources confirm the 2006 Toyota Caldina is fitted with a head gasket. The Toyota Electronic Parts Catalogue for Caldina T24# and ST246 models lists “Gasket, Cylinder Head” for the 1ZZ‑FE (1.8L), 1AZ‑FSE (2.0L D‑4), and 3S‑GTE (2.0L turbo) engines. Toyota engine repair manuals for these engines include removal/installation and torque procedures for the cylinder head and gasket, and OEM parts diagrams used by dealers and parts distributors show the head gasket within the engine mechanical section.

• Toyota Repair Manuals (Cylinder Head section) for 1ZZ‑FE, 1AZ‑FSE, and 3S‑GTE engines
• OEM parts diagrams used by dealer networks and catalogues (engine mechanical illustrations showing head/block and gasket stack)

The head gasket on a 2006 Toyota Caldina seals the mating surfaces between the engine block and cylinder head, keeping combustion pressure in while keeping coolant and oil in their own passages. On these engines it’s a multi‑layer steel (MLS) design, chosen for durability and stable sealing as temperatures and loads change. Whether it’s the chain‑driven 1ZZ‑FE and 1AZ‑FSE or the belt‑driven turbo 3S‑GTE, the gasket is critical for compression, clean emissions, and long engine life.

Head gaskets aren’t a routine “service item”
