Parts for your 1987 Suzuki Swift-Head gasket

1987 Suzuki Swift head gasket: what it does and how to look after it

Technical sources confirm a head gasket is absolutely relevant to the 1987 Suzuki Swift. The Suzuki factory service manuals for the SA/AA-series Swift and the G10/G13A engines outline cylinder head removal, gasket replacement and bolt torque stages, and the Suzuki Electronic Parts Catalogue lists head gasket part numbers for the 1.0L G10 and 1.3L G13A engines. Independent manuals such as the Haynes and Chilton guides covering Suzuki Swift/Geo Metro/Sprint models of the era also specify head gasket procedures, inspections and specs. So yes—this model runs a conventional head gasket between the alloy head and cast-iron block.

On the 1987 Swift, the head gasket seals three critical paths under the bonnet: combustion pressure in the cylinders, engine oil galleries, and coolant passages. When it’s healthy, the engine runs sweet as, holding compression, keeping coolant and oil separate, and managing temperatures across long kilometres. When it’s not, you’ll cop rough running, overheating, coolant loss and sometimes that tell-tale “milkshake” in the oil.

Owners thinking about replacement or preventative care can keep it simple. The gasket itself usually fails due to overheating or age, not bad luck. That means the cooling system is the first port of call: radiator clean and flowing, thermostat fresh, water pump and drive belts in good nick, and a proper 50/50 coolant mix. A pressure test and block test are handy if there’s any doubt.

• Common warning signs: unexplained coolant loss, white exhaust steam, bubbles in the radiator, misfire on start-up, chocolatey residue under the oil cap, or overheating under load.
• If replacing: follow the factory torque sequence from the centre out, in stages. Have the head checked and lightly skimmed if it’s not within flatness spec, clean the block deck carefully, and only use sealant where the manual specifies.
• Good practice while you’re there: fresh head bolts if they’re stretched or torque-to-yield, new timing belt and tensioner, thermostat, and radiator cap. Refill with the correct coolant and bleed the system properly.

There’s no magic maintenance trick for the gasket itself—its lifespan depends on keeping heat in check. Regular servicing, correct coolant changes and never driving on the red will give the 1987 Swift’s head gasket an easier life and keep the little G-series engine perky for years.

Popular questions about 1987 Suzuki Swift head gaskets

What are the head bolt torque specs and sequence for a 1987 Swift?
They’re detailed in the factory service manual for the specific engine (G10 1.0L or G13A 1.3L). Expect a multi-stage torque process with the sequence starting at the centre and working outwards in a criss-cross pattern. Always clean and lightly oil threads if the manual specifies, and replace any stretched or damaged bolts.

Can they drive a 1987 Swift with a blown head gasket?
Best not. Even short trips risk hydraulic lock, warped heads, washed cylinder bores and bearing damage. If it’s showing classic failure signs—overheating, steam, contaminated oil—park it, test it, and plan a repair before bigger bills pile up.

How much does a head gasket job cost on a 1987 Swift?
Costs vary with machine work and parts quality, but as a ballpark in AU/NZ: 6–10 hours labour plus a gasket set, fluids and potential head skimming. It often lands in the low four figures if done professionally, less if the head is within spec and the cooling system is already mint.
