2016-2018 Ford Transit Custom wet belt replacement

Yes. The wet belt is the engine's timing belt, which many people call the cambelt. It is called a wet belt because it runs inside the engine, in the engine oil, where an ordinary timing belt runs dry behind a cover.

So a wet belt replacement, a timing belt replacement and a cambelt change on a Ford 2.0 EcoBlue are the same job.

Originally Ford's official wet belt service interval for EcoBlue engines was 10 years or 150,000 miles, but due to premature failures, it has been revised to 100,000 miles or 6 years for models such as the Transit and Transit Custom.

In truth, it massively depends. We have seen complete wet-belt failures as low as 30,000 miles, and as high as 150,000. Largely, it depends on service intervals. We recommend belt replacements every 70,000 miles.

Service your oil and filter every 8,000 miles. This is the most critical thing you can do to prevent wetbelt failure.

In 1990, manufacturers recommended service intervals of 8,000. Modern Ford recommended service intervals are up to 24,600 miles. Oil hasn't become 3 times better. It is done to appeal to fleet buyers comparing whole life costs, and is borderline planned obsolescence. The quickest way to guarantee engine problems, is to trust these intervals. Ideally, oil and filter services every 8,000 miles prevent the oil congealing, blocking oil galleys and becoming acidic.
