1987 Suzuki Jimny head gasket: what it does, when to replace, and how to look after it

Based on technical sources including the Suzuki SJ410/SJ413 factory service manuals for the F10A and G13A engines, Suzuki’s electronic parts catalogues for the era, and the widely used Haynes manual for Suzuki SJ models, the 1987 Suzuki Jimny does use a conventional cylinder head gasket. Both the 1.0‑litre F10A (SJ410) and the 1.3‑litre G13A (SJ413/Samurai) engines are an iron block with an alloy head and rely on a head gasket to seal combustion, coolant, and oil passages between block and head.

On this vintage Jimny, the head gasket’s job is straightforward but critical: keep combustion pressure where it belongs, stop coolant and oil from swapping places, and maintain compression for smooth running and easy starts. From the factory it’s typically a composite graphite/fibre and steel fire-ring style gasket
