Does the 1.2 PureTech (EB2) have a timing belt or a chain?
The 1.2 PureTech (EB2) used by Peugeot, Citroën, DS, Vauxhall, Opel (2014 onwards) runs a wet belt (belt-in-oil). Stellantis shortened the original interval after widespread early belt breakdown. Later builds moved to a chain. Confirm which one the car in front of you has before pricing the job.
