Why the PureTech wet belt fails
The PureTech's timing belt runs inside the engine, immersed in oil rather than sitting externally like a conventional cambelt. On affected vehicles, the belt material has been found to degrade over time, particularly where oil changes have been infrequent or the wrong specification of oil has been used. As the belt breaks down, fragments circulate through the oil system and can block the oil pump pickup — starving the engine of lubrication and causing catastrophic damage that's far more serious, and expensive, than the belt itself.
Because of how widely reported this issue is, we'd strongly recommend having the belt checked or replaced preventatively if you're not certain of its history — regardless of whether you've noticed any symptoms yet.
Signs of a failing wet belt
- A rattling or whining noise from the front of the engine
- Low oil pressure warning lights
- Engine management light or misfire
- In many cases, sudden failure with no prior warning at all
Our replacement process
- Confirmation of your exact engine and belt specification from your registration.
- Fixed quote confirmed before any work begins.
- Wet belt, tensioner and associated seals replaced with correctly specified components.
- Full oil system flush to remove any belt debris already in circulation.
- Oil and filter change with the correct specification oil.
- Road test and final quality check before collection.
