Parts for your 2023 Toyota C-hr-Head gasket

2023 Toyota C‑HR head gasket — what it is and when to act

Yes, the 2023 Toyota C‑HR uses a head gasket. Toyota’s workshop manuals and parts catalogues for the 2023 C‑HR list a multi‑layer steel (MLS) cylinder head gasket for both engine options commonly fitted to this model year: the 2.0‑litre M20A‑FKS petrol and the 1.8‑litre 2ZR‑FXE hybrid. Those technical sources confirm the engine has a separate aluminium cylinder head bolted to the block, and the head gasket sits between them to keep everything sealed.

The head gasket’s job is simple but critical. It seals three things at once: combustion pressure in the cylinders, engine coolant flowing between block and head, and engine oil passing through galleries.
