Parts for your 2019 Ford Mondeo-Exhaust gasket

2019 Ford Mondeo exhaust gasket: what it does and when to replace it

Yes, the 2019 Ford Mondeo uses exhaust gaskets. This is confirmed by Ford’s Workshop Manual (WSM) for the CD391 platform (procedures in 309-00 Exhaust System and the engine-specific exhaust manifold/turbo sections) and the Ford Microcat/ECAT parts catalogue, which list gaskets at the exhaust manifold-to-cylinder head, turbocharger to downpipe (where fitted), and front pipe/catalyst sealing rings. Motorcraft service part listings also show these gaskets as renew-on-removal items.

The exhaust gasket’s job is simple but critical: it seals super-hot exhaust gases so they exit through the system cleanly, without leaks. On the Mondeo, that seal keeps the cabin free of fumes, stops that annoying ticking or chuffing sound on cold start, helps the oxygen sensors read correctly, and—on turbo and diesel models—protects performance and DPF regeneration by keeping the system airtight.
