2002 Daihatsu Gran Move Head Gasket — What It Does and When To Replace It

Yes, the 2002 Daihatsu Gran Move does use a head gasket. Technical references like the Daihatsu Electronic Parts Catalogue (EPC) and workshop manuals for the Gran Move/Pyzar list a cylinder head gasket for its four-cylinder petrol engines (commonly the K3-VE 1.5 or HD-E family, market-dependent). Those documents also outline head bolt torque sequences and cooling system specs—clear signs a conventional head gasket is fitted between the aluminium head and the engine block.

On this little MPV, the head gasket’s job is pretty straightforward but vital. It seals the combustion chambers so each cylinder makes proper compression, and it keeps engine oil and coolant in their own lanes as they travel through the block and head. When it’s healthy, there’s no mixing of fluids, no compression leaks and no dramas with overheating.

While a head gasket isn’t a regular “service item”, looking after the cooling system goes a long way to avoiding trouble. Overheating is the classic head-gasket killer, so fresh coolant, a clean radiator and a thermostat that actually does its job are worth their weight in petrol money.

• Watch for tell-tales: unexplained coolant loss, pressurised hoses from cold, white exhaust steam once warm, rough cold starts, or milky residue under the oil cap.
• If suspected, ask for a block test (checks combustion gases in coolant), compression/leak-down tests and a cooling system pressure test.
• If replacing the gasket, follow the workshop manual: clean mating faces, check head and block for flatness, and machine the head only if out of spec.
• Use new head bolts if the manual specifies torque-to-yield, and stick to the exact torque-and-angle sequence from centre outwards.
• Take the chance to fit a new timing belt (if applicable), water pump, thermostat and radiator cap, then refill with the correct coolant mix and bleed the system properly.

Expect a professional head-gasket job to take most of a day’s labour, plus parts (gasket set, bolts, fluids). Keeping the Gran Move’s cooling system serviced every 2 years or 40,000 km, using the right coolant, and fixing small leaks early are the easiest ways to keep the head gasket happy and the weekly shop-hauler running sweet.

Popular questions about 2002 Daihatsu Gran Move head gaskets

Does a 2002 Daihatsu Gran Move definitely have a head gasket?
Yes. Factory parts catalogues and workshop manuals for K3-VE and HD-E engines specify a cylinder head gasket and head bolt torque procedures, so it’s absolutely part of the engine design.

What are the first signs of a blown head gasket on a Gran Move?
Common early signs include coolant loss without obvious leaks, overheating, sweet-smelling white exhaust once warm, heater going cold at speed, or oily “mayonnaise” under the oil cap. A block test and compression test will help confirm.

Do the head bolts need replacing when doing the gasket?
Often, yes. Many Daihatsu/Toyota small fours use torque-to-yield bolts. Check the specific workshop manual for your engine code, if TTY is specified, replace them and follow the staged torque-and-angle sequence exactly.
