GENERAL INFORMATION

Arrangement of candles of an incandescence

Glow plugs are under the inlet channel.

If there are difficulties at engine start, measure at first an engine compression. If value of a compression is not enough, the engine at low temperature not to start.

The monitor of DDE is equipped with memory of malfunctions of electric parts of diesel system of injection. In OPEL firm workshops by means of the special device it is possible to consider codes of malfunctions.

Check of candles of an incandescence

For careful check (in the conditions of a workshop) it is necessary to use the ampermeter.

PERFORMANCE ORDER
1. Remove a casing of the engine and the pipeline of forcing of air over glow plugs.
2. Unscrew connecting cables from candles of an incandescence (shooter).
3. The device for check of tension connect to positive (+) to a pole of the battery and check each glow plug.
4. If the light-emitting diode lights up, a glow plug as it should be.
5. If the light-emitting diode does not burn, the glow plug is faulty, replace.

Removal

PERFORMANCE ORDER
1. Remove an inlet collector.
2. Disconnect cables (1 and 2), unscrew and check visually glow plugs. The scorched tips of candles of an incandescence usually are a consequence of malfunction of nozzles. Similar malfunctions cannot be caused by damages in or on glow plugs.
3. If the scorched glow plug (it is specified by an arrow) is found, there is not enough only its replacement. It is necessary to check also nozzles on pressure of injection and tightness (in the conditions of a workshop).

Installation

PERFORMANCE ORDER
1. Screw in glow plugs, the inhaling moment: 25 N of m.

Prevention

The moment of an inhaling should not be more as the glow plug can fail.


2. Connect a cable of candles of an incandescence, screw a nut with effort of 5 N of m.
3. Screw an inlet collector on a head of cylinders with effort of 25 N of m, replace all consolidations.
4. Screw a support of the case of the oil filter and the pipeline of system of a retsirkulyatsiya of OG on an inlet collector with effort of 25 N of m.
5. Establish into place a casing of the engine and the pipeline of forcing of air.
