2001 Daihatsu Gran Move exhaust gasket — what it does and when to replace it

Technical sources confirm the 2001 Daihatsu Gran Move (also known as the Pyzar in some markets) uses exhaust gaskets. The Daihatsu workshop manual for the G3#1 series and the Daihatsu Electronic Parts Catalogue specify an exhaust manifold-to-cylinder head gasket and a front pipe “donut”/ring gasket at the spring-joint. Major aftermarket catalogues (AJUSA, Victor Reinz, Bosal/Walker) also list these gaskets for this model and year, so an exhaust gasket is absolutely relevant and fitted to the vehicle.

On the 2001 Daihatsu Gran Move, the exhaust gasket’s job is simple but critical: it seals hot gases as they leave the engine and flow through the exhaust. The manifold gasket sits between the cylinder head and the exhaust manifold, keeping the system airtight so there’s no noisy blow, no fumes creeping into the cabin, and no dodgy readings at the oxygen sensor. The front pipe usually uses a crush-style donut gasket at a spring-loaded flange, letting the joint flex with movement while staying sealed.

There isn’t a fixed kilometre-based replacement interval for exhaust gaskets. They’re usually replaced when the joint is disturbed (for example, when removing the manifold or front pipe), or when there are signs of leakage. Regular servicing should include a quick visual and audible check. If it’s starting to leak, it’s best to sort it before it cooks nearby components or throws out fuel trims.

• Common signs: a sharp ticking or chuffing noise on cold start, sooty streaks at a flange, a whiff of exhaust under the bonnet, slight power loss, higher fuel use, or oxygen-sensor/lean codes from an upstream leak.
• Good practice on replacement: clean mating faces, use new gaskets and (where specified) new spring bolts and copper nuts, and torque fasteners to the factory spec in the Daihatsu manual. If the manual calls for it, re-check tension after the first heat cycle.
• While you’re there: check the manifold for warping or cracks, inspect studs for corrosion, and make sure hangers and mounts aren’t stressing the joints.

Done right, a fresh manifold gasket and a quality donut seal will keep the Gran Move quiet, safe, and running sweet, with the exhaust flowing as it should and the ECU getting clean sensor data.

Popular questions about 2001 Daihatsu Gran Move exhaust gaskets

What’s the usual cause of an exhaust gasket leak on a Gran Move?

Heat cycles and vibration slowly fatigue the gasket and hardware. If the manifold or front pipe has been off and reused with an old gasket, sealing can also suffer. Rusty studs and uneven mating faces are common culprits too.

Can it be driven with a leaking exhaust gasket?

It’ll usually drive, but it’s not ideal. A leak can let fumes into the cabin, can skew oxygen sensor readings (hurting fuel economy and performance), and can erode nearby components. It’s best to repair sooner rather than later.

Do I need sealant with a new exhaust gasket?

For the Gran Move’s metal/composite manifold gasket and the donut front-pipe gasket, sealant typically isn’t required and can even interfere with sealing. Fit clean, dry parts and follow the Daihatsu torque pattern and spec.
