Common failures in the timing belt of the 1.2 PureTech engine
Issues with the timing belt in the 1.2 PureTech engine have been widely reported, affecting both the car’s performance and owners’ wallets.
Premature wear of the oil-soaked belt
The oil meant to protect the belt can deteriorate it if it contains impurities. This causes the belt to release particles that contaminate the lubrication system, increasing wear on other components.
Damages caused by a faulty belt in the PureTech engine
A worn belt can lead to serious problems such as:
-
- Engine misalignment.
-
- Failures in pistons and valves.
-
- Repairs that can exceed €7.000.
Consequences of a faulty timing belt
A timing belt failure not only entails expensive repairs but can also compromise the engine’s lifespan.
Repair costs and risks to the engine
Failures caused by a faulty belt can include complete engine replacement in severe cases, as well as a significant loss of the car’s value in the second-hand market.
How to identify a timing belt failure?
Some warning signs include:
-
- Strange engine noises.
-
- Excessive oil consumption.
-
- Power loss or irregular operation. If you notice any of these symptoms, it’s crucial to visit a specialised workshop.
