Check

On models with C16 NZ, C16 NZ2 and C18 NZ engines it is necessary to check annually movement 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 recirculation of exhaust gases it is necessary to use специаль Nov the equipment Opel.

PERFORMANCE ORDER
1. Warm up the engine up to the normal working temperature on turns of idling and quickly open and close a butterfly valve. At the same time the plate of fastening of a diaphragm has to move up at change of depression in an inlet collector. During the operation of the engine on single turns, being careful, move a fastening plate up, at the same time turns of idling have to decrease approximately by 100 rpm.
2. If when conducting check the valve does not work properly, it needs to be cleaned.

Removal

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

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

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

Installation

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