2001 Daihatsu Gran Move head gasket — what it does and when to sort it

Yes, the 2001 Daihatsu Gran Move absolutely uses a cylinder head gasket. Technical references that cover this model and its engines (notably the HC‑EJ 1.3L and HD‑E/HD‑EP 1.6L inline‑fours used in the M100/M101 Gran Move/Pyzar) specify a cylinder head gasket, torque sequence, and gasket thickness options. This is documented in the Daihatsu Gran Move/Pyzar workshop manual, the Daihatsu Electronic Parts Catalogue (EPC) listing for “Cylinder Head Gasket,” and general spec databases like Autodata that include head bolt torque/angle procedures for these engines.

On this Daihatsu, the head gasket sits between the alloy cylinder head and the cast‑iron block, sealing three critical zones: combustion chambers, coolant passages, and oil galleries. It keeps compression in, and coolant and oil in their own lanes, so the engine runs smoothly and stays cool. Overheating, old coolant, corrosion, or a poorly torqued head can stress the gasket over time.

It’s not a routine replacement item, but it’s worth watching for tell‑tales: unexplained coolant loss, white steam from the exhaust, milky residue on the oil cap, persistent misfire on start‑up, pressurised hoses when cold, or a temp gauge that spikes on hills. A cooling‑system chemical test for combustion gases or a compression/leak‑down test quickly confirms suspicions.

If replacement’s on the cards, the smart play is to do it once and do it right:

• Use an OEM‑quality composite or MLS gasket and new head bolts (these engines typically use torque‑to‑yield fasteners).
• Have the head checked and skimmed if needed
