Parts for your 2016 Ford Fiesta-Exhaust gasket

2016 Ford Fiesta exhaust gasket — what it does and when to replace it

Yes, the 2016 Ford Fiesta uses exhaust gaskets. Technical sources confirming fitment include the Ford Workshop Manual (WSM) for Fiesta 2014–2017, Section 309-00 Exhaust System — General Information and Removal/Installation, which specifies gaskets at the exhaust manifold or turbo-to-cylinder head joint and at downpipe/flange connections, the Ford Electronic Parts Catalogue (EPC), which lists the exhaust manifold gasket (basic part no. 9448) and flange/donut gaskets (basic part nos. 5F297/5A231) for 1.0 EcoBoost and 1.6 Duratec engines, and the Haynes Repair Manual for Ford Fiesta 2011–2019, which details replacement of these gaskets during exhaust or turbo work.

On the 2016 Fiesta, the exhaust gasket’s job is to seal high‑temperature gases at key joints so exhaust flows cleanly through the system. Whether it’s the manifold (or turbo housing on EcoBoost) to the cylinder head, the turbo outlet to the downpipe, or a flange further back, these gaskets prevent leaks that cause ticking noises, fumes under the bonnet, poor fuel economy, and dodgy oxygen‑sensor readings. Depending on location, Fiesta gaskets are typically multi‑layer steel (MLS) plates or metal/graphite ring “donuts” that handle heat cycling and movement.

They’re not a scheduled service item, but they should be inspected during routine servicing, especially if there’s been a knock to the exhaust, the vehicle has high kilometres, or work has been done on the manifold, turbo, or catalytic converter. Replace the gasket any time the joint is disturbed. For the EcoBoost, always fit a new turbo-to-head and turbo outlet gasket, for the 1.6 petrol, renew the manifold gasket and any downpipe flange gasket when refitting.

• Common symptoms of a leak: a sharp ticking on cold start, exhaust smell in the cabin, visible soot around a joint, a slight whistle under load, or a new rattle.
• Good workshop practice: clean mating faces, follow the Ford torque specs and sequence, use new studs/nuts where specified, and avoid generic sealants unless the WSM calls for them.

If a leak is ignored, heat and escaping gases can erode flanges, skew O2 sensor readings, and potentially affect WOF/RWC and emissions. Most flange or donut gasket jobs are straightforward, manifold or turbo gaskets are more involved and best tackled with the right tools and torque data. As a rule of thumb, have the system checked whenever there’s a change in exhaust note, after rough-road use, or every service interval so minor weeps don’t turn into bigger repairs.

Popular questions about 2016 Ford Fiesta exhaust gaskets

Where is the exhaust gasket on a 2016 Fiesta?
On non‑turbo models, the main gasket sits between the exhaust manifold and the cylinder head, with another at the front pipe or catalytic converter flange. On 1.0 EcoBoost models, the turbo mounts to the head with a sealing gasket, and there’s a second gasket where the turbo outlet meets the downpipe. Further back, some joints use a donut‑style ring.

How long do Fiesta exhaust gaskets last?
There’s no fixed interval, they often last many years. Replace on signs of leakage, when removing the manifold/turbo/front pipe, or if you notice ticking, fumes, or soot at a joint. High heat cycles, short trips, and loose fasteners shorten their life.

Can someone keep driving with a leaking exhaust gasket?
It’ll usually run, but it’s not a great idea. Leaks can let fumes into the cabin, upset sensor readings, increase noise, and risk damage to flanges and studs. It’s best to sort it promptly to stay safe and compliant.
