Which used cars have wet-belt engines?

A wet belt is a cambelt that runs inside the engine oil. As it ages it sheds material into the oil, and a failure can take the engine with it — which makes it a mandatory replacement item, typically around 4 years or 60,000 miles at roughly £800–£1,500. Across the 340 models Forecourt tracks, 43 have at least one wet-belt engine in their range. They're listed below, engine by engine.

Wet belts — quick answers

What is a wet-belt engine?

A wet belt (belt-in-oil) is a cambelt that runs inside the engine's oil rather than dry on the outside. It was adopted for efficiency, but the belt sheds material into the oil as it ages, and a failed belt can destroy the engine. It is a mandatory replacement item, typically due around 4 years or 60,000 miles at a cost of roughly £800–£1,500.

Which engines are wet-belt?

The best-known are Ford's 1.0 EcoBoost and the PSA group's 1.2 PureTech (Peugeot, Citroën, Vauxhall and others). The full list of affected models and engines in Forecourt's catalogue is on this page, drawn from the same per-variant data behind each car's profile.

Should I avoid buying a wet-belt car?

Not necessarily — but budget for the belt. Ask for evidence of the belt change if the car is near or past the interval, check the service history used the correct oil specification, and price the job into your offer if it hasn't been done. A car with a fresh, documented belt change is a much safer buy than one without.
