Removal, check and installation of candles of an incandescence

If ignition was just included, or the engine just worked, the candle can remain still very hot!

Removal

Engines of 1.7 l of SOHC

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery.
  1. Weaken nuts of fastening of electroconducting of candles of the 2nd and 3rd cylinders (1) and contact tires of candles of the 1st and 4th cylinders (1). Remove the tire from candles.
  1. Turn out candles and remove them from a head of cylinders.

Engines of 1.7 l of DOHC

 PERFORMANCE ORDER

  1. Remove an air purifier and the ECM engine with a basic arm (see. Head of the Power supply system and release).
  2. Disconnect from candles electroconducting, - big and a forefinger compress lock uvulas and remove a tip from a candle shaft.
  1. Turn out candles and remove them from the engine.

Engines of 2.0 l

 PERFORMANCE ORDER

  1. Disconnect a negative wire from the battery. On engines with a high-pressure head turbo-supercharging (Y20DTH) release fastenings and lift the receiver pressurization from a turbokompressor over a final collector.
  1. On models of early years of release give fixing nuts (1), remove washers, disconnect electroconducting and remove the contact tire of a food of candles of an incandescence. On models of the last years of release simply disconnect from candles electroconducting.
  1. Turn out candles and remove them from the engine.

Check

 PERFORMANCE ORDER

  1. Check candles on existence of mechanical damages. Or an erosion of tips violation of serviceability of functioning of sprays of nozzles can be a consequence of Progara. Check a condition of nozzles, replace defective components.
  1. Make sure of lack of a burn-out of tips of candles, - in case of need make replacement. If outwardly candles look serviceable, check them by means of an ohmmeter (see. Removal and installation of the sensor of emergency pressure of oil).
  1. Check of operability of a glow plug can be checked by a way of giving of tension on it 12 In, - the serviceable candle should be heated in due time (be careful, do not burn):
    1. The power supply should be equipped with the fuse for protection against short circuit.
    2. Clamp a candle in a vice with soft sponges, - do not forget that its working element is heated until red.
    3. After check let's to a candle cool down within several minutes not to burn.

The working element of a serviceable candle should become red-hot no later than in 5 seconds. If the warming up of a candle needs much more time, or the tip is heated only in an average part, it is necessary to replace a candle.

Installation

Engines of 1.7 l of SOHC

 PERFORMANCE ORDER

  1. Accurately screw candles and tighten them with demanded effort, - remember that the tightening of candles with excessive effort can lead to carving damage.
  2. Put on the food tire the central conclusions of candles and reliably tighten nuts on candles of the 1st and 2nd cylinders.
  3. Connect electroconducting to candles of the 2nd and 3rd cylinders, tighten fixing nuts.
  4. Connect a negative wire to the battery.

Engines of 1.7 l of DOHC

 PERFORMANCE ORDER

  1. Accurately screw candles and tighten them with demanded effort, - remember that the tightening of candles with excessive effort can lead to carving damage.
  2. Connect to candles electroconducting of giving of a food.
  3. Establish ECM, with a basic arm and an air purifier (see. Head of the Power supply system and release).

 PERFORMANCE ORDER

  1. Accurately screw candles and tighten them with demanded effort, - remember that the tightening of candles with excessive effort can lead to carving damage.
  2. On models of early years of release put on the food tire conclusions of candles, attach electroconducting, establish washers, then screw and reliably tighten fixing nuts. On models of the last years of release simply connect to candles electroconducting.
  3. If removed, establish a metal tube of a turbokompressor, then connect a negative wire to the battery and check serviceability of functioning of candles of an incandescence.
