Parts for your 2002 Daihatsu Gran move-Exhaust gasket

2002 Daihatsu Gran Move exhaust gasket – is it a thing on this model?

Yes, the 2002 Daihatsu Gran Move is built with exhaust gaskets and they’re relevant to routine exhaust work on the vehicle. Technical sources including Daihatsu’s service literature and the Daihatsu/Toyota Electronic Parts Catalogue (EPC) for the Gran Move/Pyzar platform list a cylinder-head-to-exhaust-manifold gasket and a front pipe “ring” or donut gasket between the manifold (or manifold/catalyst outlet) and the exhaust front pipe. Workshop procedures specify replacing these gaskets when the manifold or front pipe is removed, and provide torque and tightening sequence guidance for refitting.

• Daihatsu Gran Move/Pyzar (G3 series) Service Manual: Engine Mechanical and Exhaust sections – removal/refit procedures specify replacement of the exhaust manifold gasket and front pipe gasket.
• Daihatsu/Toyota Electronic Parts Catalogue (EPC) – Gran Move/Pyzar model (G303/G311): exhaust group lists “Gasket, Exhaust Manifold” and “Gasket, Front Exhaust Pipe (ring)”.
• Aftermarket technical catalogues (e.g., OE-equivalent gasket listings) for Gran Move/Pyzar 1.5–1.6 petrol engines include exhaust manifold and flange/donut gaskets for 1996–2002 production.

The exhaust gasket on a 2002 Daihatsu Gran Move is a small bit of kit that does a big job. Sitting between the cylinder head and the exhaust manifold (and again at the manifold-to-front-pipe joint), it seals hot gases so they flow cleanly through the system. That keeps the car quiet, protects the cabin from fumes, and lets the oxygen sensor read properly so fuel trims stay on song. On a two-decade-old Gran Move, a tired gasket can cause a sharp ticking on cold start, a whiff of exhaust under the bonnet, sooty streaks at the flange, and even a check engine light from skewed O2 readings.

There’s no fixed replacement interval in the factory schedule, but any time the manifold or front pipe is removed, new gaskets should go in. During regular servicing, it’s smart to:

• Inspect for black soot marks around the manifold and front pipe joint, and listen for leaks on cold start.
• Check manifold nuts/studs and the spring-bolt hardware at the front pipe, replace corroded fasteners and the donut/ring if crushed or cracked.
• Avoid sealants, use the correct multi-layer metal or graphite gasket specified for the engine, and follow the workshop manual torque pattern.
• Mind the oxygen sensor and nearby catalyst—heat and leaks here can snowball into drivability and fuel economy issues.

If a leak’s found, most shops will knock it over quickly: cool the engine, remove the heat shield, free the fasteners, clean the mating faces, fit new gaskets, then torque to spec in stages. In Aussie and Kiwi conditions—coastal air, plenty of short trips—fasteners can seize, so soaking them ahead of time and having new hardware on hand is a good shout. Get it sealed properly and the Gran Move will stay quiet, safe, and compliant for rego or WOF.

Does the 2002 Gran Move have more than one exhaust gasket?

Yes. There’s a manifold-to-head gasket, and typically a ring/donut gasket at the manifold or catalyst outlet to the front pipe. Some cars may also have flat flange gaskets further down the system depending on build and market.

How often should the exhaust gasket be replaced?

There’s no set kilometre interval. Replace any time the joint is disturbed or if you notice ticking, fumes, soot marks, or a CEL related to exhaust leaks. Given the age of these cars, proactive replacement when doing other exhaust work is sensible.

Is it safe to drive with a leaking exhaust gasket?

It’s not recommended. Apart from noise and fumes, a leak can pull fresh air into the exhaust, confusing the O2 sensor and making the engine run rich. That can hurt fuel economy and the catalyst. Get it sorted promptly.
