Video tutorial

In this video, see the internal structure of a Renault 1.5 dCI K9K engine, which is fitted in various vehicles (including Nissan, Dacia, Mercedes). We see the turbo group, EGR valve, heat exchanger, exhaust gas compensation valve, intake pipe, cylinder head, and especially the fifth injector, which injects fuel after the exhaust and goes into the particulate filter via a flexible pipe.

In the second part of the video, we can see the perfect cleaning of the engine seat before installing the head gasket; we then see the conclusion of the work: the engine reassembled and starting the vehicle without any warning lights coming on.
