Parts for your 2006 Ford Fiesta-Exhaust gasket

2006 Ford Fiesta exhaust-gasket: what’s fitted and how to look after it

Yes, the 2006 Ford Fiesta does use an exhaust-gasket. Technical documentation confirms it’s part of the exhaust sealing set-up on these cars. The Ford Workshop Manual for the Fiesta Mk6 (2002–2008) specifies a gasket at the exhaust manifold-to-cylinder head interface, and most engines in this model also use a sealing ring or gasket at the manifold-to-front pipe/catalyst joint. The Haynes Ford Fiesta Petrol & Diesel 2002–2008 manual likewise lists the exhaust manifold gasket as a replace-on-removal item, and OEM/aftermarket parts catalogues show dedicated “gasket – exhaust manifold” listings for 1.25/1.4/1.6 Duratec petrol and 1.4/1.6 TDCi diesel variants.

On the 2006-ford-fiesta, the exhaust-gasket’s job is simple but critical: keep exhaust gases sealed inside the system so they flow through the catalytic converter and mufflers, not out under the bonnet. A healthy seal prevents that tell-tale tick on cold start, stops sooty blow-by at the flange, and helps the oxygen sensors read correctly. That means smoother running, better fuel economy, and fewer headaches at a WOF or roadworthy.

If the exhaust-gasket has started leaking, expect a sharp tapping noise that quietens as things heat up, a whiff of exhaust odour near the engine bay, or black carbon traces around the joint. Left alone, a leak can skew fuel trims, trigger a check-engine light, and in worst cases, let hot gas cook nearby wiring or plastic clips.

Servicing advice for a Fiesta exhaust-gasket is pretty straightforward:

1. Any time the manifold or front pipe is removed, fit a new exhaust-gasket. They’re designed to crush once and won’t reliably reseal twice.
2. Clean both mating faces until they’re spotless
