Summary in 10 Seconds Belt to chain conversion kits for PureTech 1.0 and 1.2 engines are available for pre-order. Two separate kits were prepared for atmospheric and turbo engines. Delivery of the first production series is expected in the second half of 2026. Sales and customer account access is currently only available to the professional service channel. This time, a direct mechanical solution is on the agenda for the wet timing belt issue that PureTech engine owners have been following closely for years.
The oil-bath belt system used in the 1.0 and 1.2 PureTech engines of the PSA/Stellantis group has been on the agenda of many users due to the risk of wear and tear over time. Netherlands-based Pro Chain has made the kits that convert the belt-driven timing system in these engines into a chain structure available for pre-order. For now, the kits are not offered directly to the end user, but through sales channels for services, repair shops and professionals in the automotive industry.
The era of chains instead of belts begins in PureTech engines. At the center of the discussion in the PureTech engine family is the timing belt system running in oil. This structure, unlike the classic dry timing belt, works in contact with engine oil. This is exactly where the problem starts. The wear and tear of the belt over time and the release of particles can cause different problems in the engine. Conversion kits prepared by Pro Chain contain the necessary parts to convert the existing belt timing system to a chain system.
In the official product descriptions, it is stated that the components related to the chain, gears, slides, tension mechanism and oil system are included in the kit. There are separate kits for two different engine types. The kits are not offered in a single type. Since the mechanical structures of the naturally aspirated and turbocharged engines in the PureTech family are different, two separate conversion sets have been prepared.
Thus, separate compatibility is provided for atmospheric engines and turbo engines. This distinction is important. Because there are engines with different power levels and different technical structures under the PureTech name. The suitability of the conversion kit for the vehicle must be checked based on the engine code and existing mechanical structure. Deliveries are expected in the second half of 2026. Conversion kits are currently in the pre-order phase.
The estimated delivery period for services booking the first production series is shared as the second half of 2026. It is also stated that the delivery date may change depending on production planning. There is no clear information on the price side. It is also noteworthy that the kits are not positioned as a retail product available to the end user. Sales and account access is limited to services, repair shops and professionals in the automotive industry.
It does not mean a direct solution for every PureTech owner. The release of this kit is an important step in terms of the wet belt debate in PureTech engines. However, this does not mean that every vehicle can be directly converted into a chain or that it can be applied immediately by every service. Headings such as compatibility, assembly procedure, workmanship quality, warranty status and the current condition of the vehicle will be decisive here.
For this reason, the conversion process should not be seen as an ordinary maintenance part replacement. It would not be right to make a decision without checking the engine code and service history.
