Parts for your 1991 Suzuki Swift-Head gasket

1991 Suzuki Swift head gasket: what it is, what it does, and when to sort it

The 1991 Suzuki Swift does use a conventional cylinder head gasket across its petrol engines (G10 1.0L three‑cylinder and G13 1.3L SOHC/DOHC including GTi). This is documented in the Suzuki Swift/Geo Metro Factory Service Manual (1989–1994 editions), the Suzuki Electronic Parts Catalogue (lists “Gasket, Cylinder Head” under the cylinder head group for G10 and G13 engines), and independent manuals such as the Haynes Suzuki Swift 1989–2001. So a head gasket is absolutely relevant on a ’91 Swift.

The head gasket sits between the alloy cylinder head and the cast‑iron block, sealing combustion pressure while keeping engine oil and coolant in their own lanes. On a 1991 Swift, that wafer‑thin seal is the quiet achiever that keeps it peppy, leak‑free, and economical on Aussie and Kiwi roads. If it lets go, you’ll often see overheating, milky oil, white exhaust steam, or a stubborn misfire.

Replacement isn’t a routine service item
