Check

Check each glow plug on existence of mechanical damages. The burned or destroyed tips of a glow plug can be from a bad stream of dispersion of fuel a nozzle. If there is such damage it is necessary to check and if necessary to replace fuel nozzles.

If glow plugs have no mechanical damages, check their electric resistance which owes a life less than 1 Ohm.

Operability of candles of an incandescence can be checked, submitting on them 12 volts. Thus they should heat up evenly and for a demanded interval of time. Thus it is necessary to observe precautions:

To hold a glow plug a special clip or flat-nose pliers.

The electric power-supply circuit of a glow plug should have the fuse.

After check the glow plug should be cooled within several minutes.

The glow plug in a good condition heats up to reddening of a working konik within 5 seconds. At longer heating or heating in an average part, instead of on the candle end the candle is faulty and is subject to replacement.

Installation

Installation is made in sequence, return to removal.
