Repairs & Replacements
Wet Belts
A wet belt (also called an oil-bathed timing belt) runs inside your engine submerged in oil, rather than dry like a traditional cam belt. They're found in many modern engines and require specialist knowledge to inspect and replace correctly. Left too long, a worn wet belt can cause serious, and costly, engine damage.
What's Involved

Common Questions
Wet Belts FAQ
How do I know if my wet belt needs replacing?
Most manufacturers recommend replacement every 5–7 years or 80,000–100,000 miles, whichever comes first. Check your vehicle handbook or ask us if you're unsure.
Does a wet belt replacement include an oil change?
Yes. Because the wet belt runs in oil, fresh engine oil and a new filter are always fitted as part of the job. There's no point fitting a new belt into contaminated oil.
How is a wet belt different from a cam belt?
A traditional cam belt runs dry, outside the engine. A wet belt runs inside the engine submerged in oil, which can make it harder to inspect and more involved to replace. Not all garages have experience with them, but BS Services are wet belt specialists.
What happens if my wet belt snaps?
In most cases, catastrophic engine damage. Valves and pistons can collide, resulting in a repair bill that often exceeds the value of the car. Replacing the belt on schedule is far cheaper than the alternative.
