Wet belt replacement in

What is a wet belt?

A wet belt is a timing belt that runs inside the engine, in the oil. Not outside in the open like a traditional cambelt. Ford and PSA went with this design because it's quieter and lower friction. The trade-off is that the rubber sits in hot oil for its whole life.

Why it's a known weak point

Over time the belt degrades and sheds tiny rubber particles into the engine oil. Those particles get sucked into the oil pump pickup strainer and block it. Once the pump can't pull oil, pressure drops, bearings let go and the engine destroys itself. We've seen perfectly healthy-sounding cars come in with a blocked pickup and a scrap engine inside a week.

Manufacturers don't always make the interval obvious. Plenty of owners don't even realise their car has a wet belt, never mind when it needs doing. Service schedules have been revised down more than once on PureTech engines.

What we do. And what we don't

We replace the wet belt with a genuine like-for-like kit at the correct interval for your exact engine. Belt, tensioner, guides, oil pump pickup checked, engine oil and filter renewed with the manufacturer-specified grade. The job is done properly, once, the way the manufacturer intended.

We do not convert wet belt engines to chain or dry belt. Anyone offering that on a 1.0 EcoBoost or 1.2 PureTech is either misleading you or rebuilding the engine. The correct fix is a fresh wet belt kit, fitted before the old one fails.

Why getting it done on time matters

Replacing the belt costs a fraction of replacing the engine. Once the pickup is blocked the bill jumps from hundreds to thousands. And at that point you're looking at a used engine, not a repair. If your car is on the list below, don't wait.
