A Coruña, Spain – The YouTube channel “VAICO” sheds light on a critical point of Peugeot and Citroën PureTech engines: the operation of wet timing belts. This technology, which allows the belt to run in an oil bath, has been adopted by several manufacturers with the promise of smoother operation, reduced wear and longer replacement intervals. However, the reality has proven to be very different for thousands of owners.
The video visually details how a defective belt can widen, become incompatible with other engine components, or even deteriorate and break completely. This failure not only compromises the integrity of the engine, but also generates a number of serious secondary problems.
The devastating consequences of a degraded belt
One of the most critical aspects highlighted in the video is how particles dislodged from the deteriorated belt can clog the oil pump and vacuum pump filters. This clogging is a major risk, as insufficient lubrication of the motor can lead to severe internal damage and even total failure. In addition, an affected vacuum pump can result in a critical reduction in braking power, putting safety at risk. The video clearly shows a contaminated oil filter, which reinforces the need to replace the oil pump and check the vacuum pump in such cases.
Palliative solutions: the expert replacement kit
To address this issue, the video presents an expert kit designed for complete timing belt replacement. This kit includes not only the belt itself, but also other essential components such as gaskets, a flat belt for the water pump, a new oil filter, pulleys and the appropriate bolts. In addition, it highlights the inclusion of the correct type of engine oil, differentiated for turbocharged and non-turbocharged engines, a crucial detail given that the use of an unsuitable oil can accelerate belt deterioration.
The content of “VAICO” provides a fundamental technical perspective to understand the origin of many of the PureTech problems and the replacement solutions available on the market.
