Check

On models with C16 NZ, C16 NZ2 and C18 NZ engines it is necessary to check annually moving of a plate of fastening of a diaphragm of the EGR valve as follows. For check it is necessary to use a small lamp and a small mirror as the plate of fastening is visible only through an aperture from a reverse side of the valve. On models with X16 SZ engines for check of system of a retsirkulyatsiya of exhaust gases it is necessary to use специаль aching Opel equipment.

PERFORMANCE ORDER
1. Warm up the engine to normal working temperature on turns of idling and quickly open and close a butterfly valve. Thus the plate of fastening of a diaphragm should move up at change of depression in an inlet collector. At operation of the engine on single turns, being careful, move a fastening plate up, thus turns of idling should decrease approximately by 100 rpm.
2. If at carrying out check the valve does not work properly, it is necessary for cleaning.

Removal

Detachment of a vacuum hose from the valve of system of repeated burning of exhaust gases

Removal of the valve of system of repeated burning of exhaust gases

PERFORMANCE ORDER
1. Disconnect from the valve a hose, then unscrew and remove the valve (see fig. A detachment of a vacuum hose from the valve of system of repeated burning of exhaust gases, Removal of the valve of system of repeated burning of exhaust gases). Using a wire brush, clear the valve of a deposit. Replace valve laying.

Installation

PERFORMANCE ORDER
1. Installation is made in sequence, return to removal.
2. Check operation of the valve and if it does not work properly, replace it.
