About the PureTech 1.2 wet timing belt
The PureTech 1.2 is one of the most widely used small petrol engines in Europe, and one of the best known for wet belt trouble. Its recommended belt interval has been reduced several times and now sits at around 6 years or 62,000 miles.
When the belt starts to break down, the debris can block not only the oil pickup but also the strainer for the brake vacuum pump, which reduces brake assistance. That is why we clean both and never just fit a new belt into a contaminated engine.
Common problems
- Belt delamination shedding rubber into the oil
- Blocked oil pickup and low oil pressure
- Blocked brake vacuum pump strainer, reducing brake assistance
- High oil consumption on some engines
Replacement interval
The manufacturer guide for the PureTech 1.2 is every 6 years or 62,000 miles, whichever comes first. Treat it as a maximum. Short journeys, towing and long gaps between oil changes all age the belt faster.
