1998 Daihatsu Gran Move head gasket: what it does and when to replace it

Yes, a head gasket is absolutely used on the 1998 Daihatsu Gran Move (G300 series, also known as Pyzar). Technical sources that list or illustrate the part include the Daihatsu G300 workshop manual and Electronic Parts Catalogue, along with Australian and New Zealand aftermarket catalogues from well-known gasket suppliers (such as Permaseal/ACL and Victor Reinz) that provide head gasket and full head set listings for the H‑series inline‑four petrol engines fitted to this model. These references confirm a conventional cylinder head gasket between the aluminium cylinder head and the cast‑iron block.

On this Gran Move, the head gasket seals three critical paths: combustion pressure in the cylinders, coolant passages, and oil galleries. When it’s healthy, the engine runs smoothly, holds compression, and keeps oil and coolant where they belong. When it’s tired or has been stressed by overheating, owners may see tell‑tales like rising temperature, white exhaust steam, oil that looks milky, coolant loss with no external leaks, rough starting, or a sweet smell from the exhaust.

Because the head gasket lives a hard life—especially if the cooling system’s been neglected—sensible servicing helps it last. For this model, it pays to keep coolant fresh (correct spec and concentration), ensure the radiator is clean and flowing, and replace the thermostat and radiator cap at reasonable intervals. Any sign of overheating should be fixed straight away
