Wet belt (belt-in-oil)
Ford · 2016 onwards. Oil-immersed belt driving the pump as well as the cams. Sludge in the sump or a low oil-pressure warning are the tell-tale signs.
The manufacturer schedule is 150,000 miles or 10 years, but independent specialists commonly advise shortening it to around 100,000 miles or 6 years on belt-in-oil engines. Treat an unproven belt history as a price conversation.
Commonly Focus, Kuga, Transit Custom, Mondeo (2016 onwards). Engine codes changed through production, so confirm the code on the car in front of you before ordering parts or quoting the job.
The 1.5 / 2.0 EcoBlue diesel used by Ford (2016 onwards) runs a wet belt (belt-in-oil). Oil-immersed belt driving the pump as well as the cams. Sludge in the sump or a low oil-pressure warning are the tell-tale signs.
The published schedule is 150,000 miles or 10 years, whichever comes first. Many independents advise shortening that to around 100,000 miles or 6 years on wet-belt engines. Always confirm against the car's own service book, because intervals vary by market and build date.
Expect roughly £700-£1,500 at a UK independent garage, depending on whether the water pump and tensioner go in at the same time and how much has to come off to reach the belt. Main-dealer quotes usually sit above that range.
A belt-in-oil runs inside the engine and often drives the oil pump. As it ages the belt material breaks down into the oil and can block the pickup, so a belt that is never seen from outside can destroy the engine. That is why oil-change history matters as much as the belt itself.
Commonly Focus, Kuga, Transit Custom, Mondeo (2016 onwards). The list is not exhaustive and engine codes changed through production, so confirm the exact code on the car in front of you before ordering parts or quoting work.
