Parts for your 2018 Ford Fiesta-Oil seals

2018 Ford Fiesta oil-seals: what they do and when to sort them

Based on technical documentation, oil-seals are absolutely fitted to the 2018 Ford Fiesta. The Ford Workshop Manual for the Fiesta (WSM, powertrain sections 303 and 308), Ford parts catalogues (ETIS/Microcat), and major seal manufacturers’ application data all list crankshaft front and rear oil-seals, camshaft oil-seals, and transaxle/driveshaft output oil-seals for this model. That means oil-seals are relevant items for servicing and repair on any 2018 Fiesta variant, from the 1.0L EcoBoost to manual and automatic gearboxes.

On a 2018 Ford Fiesta, oil-seals keep engine and gearbox fluids where they belong and road grime where it doesn’t. They’re tucked around rotating shafts — think crankshaft, camshafts and the gearbox’s input and output shafts — using a precision rubber lip to hold back hot oil while the shaft spins at speed. Done right, they’re invisible. When they’re not, owners start seeing drips on the driveway, a whiff of burnt oil under the bonnet, or damp, oily dust near the inner CVs.

There’s no set kilometre interval for replacing oil-seals
