 PERFORMANCE ORDER

1. Release a fixing clamp and disunite the contact socket of electroconducting of a heating element.

2. Turn out the screw (ы) fastenings of the contact socket of a heating element to the throttle case, then separate the socket and carefully take an element from the throttle case. Check a condition of a sealing ring, in case of need make replacement.
3. Installation is made upside-down. Do not forget to replace the failed sealing ring. Track, that electroconducting of a heating element did not appear is clamped at a screw tightening (ов) socket fastenings.

Models of 2.0 l

Fuel highway and injectors of injection of fuel

Before the beginning of performance of procedure attentively familiarize with section Power supply system preventions - petrol models!


Before making the decision on replacement of a faulty injector, test on it any of widespread now special cleaners.


 PERFORMANCE ORDER

1. Disconnect a negative wire from the battery.
