1.2 PureTech Wetbelt – Timing Belt Failure Risks Bedford

The 1.2 PureTech engine (used widely across PSA Group vehicles) uses an internal “wetbelt” timing system — a rubber belt running inside the engine and lubricated by oil. It’s compact and quiet, but this system has a well-documented history of early failures.

• One of the most serious issues is the shedding or breakdown of belt teeth.
   
• The rubber can soften and degrade due to constant exposure to hot oil and contaminants.
   
• Once teeth start to strip, the belt slips, throwing off the engine’s timing — a situation that can lead to catastrophic engine failure.

• As the belt breaks down, rubber particles circulate in the oil and can clog the oil pickup.
   
• This leads to oil starvation, especially to the turbocharger and top-end of the engine, increasing the risk of total failure.

• Many drivers receive no warning — failure can happen well before the scheduled interval, even under 60,000 miles.
   
• Timing failure can cause:
   
• Valve damage
   
• Piston damage
   
• And in some cases, a full engine replacement.

• PSA has revised the service interval on many models — now recommending wetbelt replacement as early as 60,000 miles or 6 years.
   
• Regular servicing with the correct oil spec is essential.
   
• Preventative replacement is far cheaper than a new engine.
   

 At CarsUpkeep, we offer expert wetbelt replacements for 1.2 PureTech engines. Our technicians are trained in this specific issue and use upgraded belts and components to help prevent early failure. We’ll also check for oil contamination and clean the pickup if needed — giving your engine a fresh start and peace of mind.
