1. Installation is made in sequence, return to removal. Add cooling liquid in cooling system.

ELECTROMAGNETIC EXECUTIVE MECHANISM

Removal

PERFORMANCE ORDER
1. The electromagnetic executive ARA mechanism is fixed by bolts on a back part of the fuel pump of a high pressure. On the cars equipped with electronic control with turns of idling of ELR and an anti-detonation control system of ARA the electromagnetic executive mechanism it is located below (see fig. Side view of a back part of the fuel pump of a high pressure).
2. Remove a weight wire from the accumulator.
3. On models without a turbo-supercharging remove the air filter.
4. Disconnect the electric socket from the executive mechanism.
5. Unscrew two bolts and remove the case of the executive mechanism from a back part of the fuel pump of a high pressure. Remove a sealing ring and a pusher.

Installation

PERFORMANCE ORDER
1. Installation is made in sequence, return to removal. At installation of the executive mechanism establish a new sealing ring. At installation of the new executive mechanism remove from the old executive mechanism a pusher and establish on the new executive mechanism.
