| Important preliminary information and measures | ||
Due to the large quantity of components comprising the assembly formed by the ENR system control valve ENR (ECAS), it has been divided in two blocks, the two blocks are identified by the markings engraved on the solenoid valves: I = Block one II = Block two | The identifications I and II are engraved on the solenoid valves beside the 4-pin outlet of each block. The sealing rings supplied with the repair kit are always measured by the inside diameter and in the thickness of the cylindrical part. | ||
To disassemble the control valve assembly, utilize a clean workbench, duly lined with a light color paper sheet to facilitate the identification of the large quantity of components Disassemble, clean and lubricate first the block II and then the block I | The only permissible lubricant is supplied with the repair kit.
