Wet Belt FAQ

Wet belts, explained

What is a wet belt?
A wet belt is a timing belt that runs inside the engine, bathed in oil — unlike a traditional dry belt or chain. Manufacturers including Ford, Peugeot, Citroën and Vauxhall use them to reduce friction and emissions. The trade-off is that they wear from the inside out and must be replaced on schedule.
Why do wet belts fail?
As the belt ages it breaks down in the oil and sheds rubber particles. Those particles can block the oil pickup pipe, starving the engine of lubrication and causing severe — often terminal — damage. Extended service intervals and the wrong oil accelerate the process.
When should it be replaced?
As a guide, every 6 years or around 60,000–100,000 miles depending on the engine — but many specialists now recommend earlier replacement. If you're unsure, send us your reg and we'll confirm the correct interval for your exact vehicle.
Which cars have wet belts?
Common examples include the Ford 1.0/1.5/1.6 EcoBoost (Fiesta, Focus, Puma, Kuga, EcoSport, Mondeo, Transit), Peugeot & Citroën 1.2 PureTech, and many Vauxhall models sharing PSA engines. Not sure if yours has one? Just ask.
Is replacement expensive?
Preventative replacement is a fraction of the cost of a new engine. Our wet belt packages start from £575 for PSA engines and £975 for the complete Ford EcoBoost job — versus several thousand pounds for an engine rebuild after a failure.
Can you do it at my home?
Yes — that's our speciality. The full wet belt replacement is carried out on your driveway or at your workplace anywhere across Wales and England, including Cwmbran, Newport, Cardiff and beyond.
