Parts for your 2001 Daihatsu Gran move-Manifold gasket

2001 Daihatsu Gran Move manifold gasket

Yes, a manifold gasket is absolutely used on the 2001 Daihatsu Gran Move (also known as the Pyzar). Both the intake manifold gasket and the exhaust manifold gasket are specified for the HC‑EJ 1.3 and HE‑EG 1.5 engines used in this model. This is documented in Daihatsu’s G3‑series workshop manual and shown in the Daihatsu Electronic Parts Catalogue, common Australasian parts listings (e.g., full VRS gasket sets) also include these manifold gaskets for the Gran Move. So it’s a relevant, fitted component on this vehicle.

The manifold gaskets seal the mating surfaces where the manifolds bolt to the cylinder head. On the intake side, the gasket keeps unmetered air out to maintain proper vacuum and fuel trims, on the exhaust side, it prevents hot gas leaks and protects nearby components. When a gasket fails, the Gran Move can show a rough idle, a check-engine light from lean mixtures, a whistling or hissing under the bonnet (intake), or a ticking noise and sooty marks near the manifold (exhaust). Fuel economy can take a hit, and exhaust leaks can be noisy and a bit stink under load.

These gaskets aren’t a routine “time-based” service item, they’re replaced when there’s a leak, whenever the manifold is removed, or if the mating surfaces have been disturbed. A tech following the Daihatsu manual will clean the flanges, check manifold flatness, and fit a new quality gasket (MLS or graphite-composite as specified). Sealant generally isn’t used unless the manual calls for a dab at specific junctions. Fasteners are tightened in the correct sequence and to the torque listed in the service data, on exhaust manifolds, it’s good practice to recheck torque after a couple of heat cycles. Replacing tired studs, spring washers and copper nuts helps the repair last.

For owners, the best maintenance is paying attention: any new hiss, tick, exhaust smell in the engine bay, or unexplained lean codes (like P0171) is a cue to book the car in. If the intake or exhaust manifold is coming off for other work—say, a head gasket or timing service—budget for new manifold gaskets at the same time. It’s inexpensive insurance that keeps the Gran Move running sweet and within emissions.

• Symptoms to watch for: rough idle, lean fault codes, hissing/ticking sounds, soot at the manifold, loss of power, poor economy.
• Good practice: new gaskets on reassembly, correct torque and sequence, inspect studs/nuts, and check for warpage.

Popular questions

Does the 2001 Daihatsu Gran Move actually have a manifold gasket?

It does. The model uses both intake and exhaust manifold gaskets on HC‑EJ and HE‑EG engines. This is stated in the Daihatsu G3‑series workshop manual and shown in the Daihatsu EPC, and the gaskets are included in common VRS kits sold in Australia and New Zealand for this vehicle.

How often should the manifold gasket be replaced on a Gran Move?

There’s no fixed kilometre interval. Replace the gasket if there’s a leak, any time the manifold is removed, or if the sealing surface has been cleaned or machined. Many techs also renew manifold nuts, studs and washers during the job for reliability.

What are the tell‑tale signs of a failing manifold gasket?

Intake leaks usually cause a rough idle, a hissing sound, lean fuel trims and possibly a check‑engine light. Exhaust leaks often sound like a sharp tick on cold start that gets louder under load, with soot traces near the manifold. Left alone, both can affect drivability and emissions.
