Purpose (to the actuator (nozzle):
- + nozzles - green-white
- Injector A - to terminal 1
- Injector B - to terminal 3
- nozzles - yellow-white
- Injector A - to terminal 2
- Injector B - to terminal 4
13.11 Installing the nozzles
12. Push the nozzles in by hand, turn the body over and make sure the nozzles are installed correctly.
13. Lubricate the wire seal (photo).
13.13 Lubricating the through-wire seal with silicone compound
1. Push
14. Install the nozzle cover, tighten the screws, lubricate with a fixing compound and tighten in a cross pattern.
15. Lubricate the housing gasket with silicone compound (Install the air filter only after the silicone sealant has set).
16. Install the damper body in reverse order.
17. Make sure there are no leaks, check the quality of the mixture in a car service (to make sure that there is no air leakage through the upper seal of the nozzle).
Direct injection systems
18. Decompress, disconnect battery from ground and drain fluid.
19. Disconnect the wires from the candles, remove the distributor cap and take the wires to the side.
