The Puretech engine from 2017 in the Citroen C3 in the video (and not only in this model) has a weak point: the oil-bath timing belt which, after only 45,000 miles (approximately 72,000 kilometres), has failed. The material has degraded and crumbled, clogging the oil pump and causing severe engine damage.

This is a known problem, but there is a solution. The manufacturer has updated the replacement with a new generation belt, more resistant to wear and made with improved materials.

Additionally, it is recommended to replace the engine oil with a specific low-viscosity oil (5W30 or 0W30) and to perform changes more frequently, every 5,000-6,000 miles, to reduce debris accumulation. If your Puretech is still under warranty, you may receive a free replacement of the belt; otherwise, take preventive action: change the belt and oil pump before a failure occurs, which costs much less than a complete overhaul.

Check the chassis number on the Citroen website to see if your engine is among the affected batches. Careful maintenance can save the engine.

Once unlocked, tilt the seat upwards and forwards to remove it from its position. Repeat this process for both sides of the rear seat. Be careful of any electrical cables or components that may be connected to the seat during removal. Once the rear seat is removed, the disassembly is complete.
