Subaru Legacy/Outback

1. In most cases replacement of spark plugs requires existence of a special candle head (with an elastic insert inside) complete with the ratchet drive, and also a set of extenders of the drive of a key and the adaptation for check and correction of interelectrode gaps. For a safe detachment of tips of VV of wires from shafts of spark plugs the special tool though its application and is not strictly obligatory is also issued. Use of a dinamometrichesky key will allow to achieve the correct effort of a tightening of candles.
2. It is most correct to keep constantly in the car a set of replaceable spark plugs with the adjusted interelectrode gap. Upon purchase of new candles watch that they met for the parameters the requirements of the engine of your car. Necessary information is provided in Specifications to the present Chapter, and also on VECI label fixed under a cowl (in case of different interpretations the preference should be given information with VECI).
3. Start a reversing of candles only after full cooling of the engine. Not to waste in vain time, use a pause for check of a condition of a replaceable set. Attentively examine new candles, - at identification of the slightest cracks in an insulator the corresponding candle has to be rejected. Measure the size of interelectrode gaps of a new set (see further).

4 Interelectrode gap of a candle is checked by introduction to it of the corresponding probe of the measuring instrument and has to conform to standard requirements. The demanded thickness the probe has to with an easy resistance slip between lateral and central candle electrodes. Correction of a gap can be made by means of the special adaptation which is usually a part of the measuring instrument - turn in appropriately lateral electrode of a candle.

5 If the lateral electrode is located not precisely over central, correct its situation as appropriate. Make sure of lack of cracks and other damages to a porcelain insulator of a candle. Existence of any sort of defects of an insulator is inadmissible. If the face surface of the central electrode is close to a hemisphere.

In order to avoid violation of an order of ignition at connection of an electrical wiring it is necessary to make an obsla chewing of each of candles in an individual order.

1. Disconnect a negative wire from the battery.
2. Remove an inlet chamber of an air path assembled with an air inlet sleeve.

3. Disconnect an electrical wiring from pumps of supply of liquid of washing of glasses. On the models equipped with a screen wiper of back glass, disconnect a hose of a washer of back glass and a zakuporta the nipple socket a suitable plug.

4. Turn out two fixing bolts, remove the tank of the washing liquid and take it aside.

5. Disconnect VV a wire from a spark plug of the first cylinder, - pull only for a tip, and not for a wire at all! It will be reasonable to use the special adaptation.
6. In the presence of near at hand source of compressed air, use it for removal of garbage from candle niches of the engine (the ordinary bicycle pump will be suitable for this purpose also not worse).

When using compressed air do not forget to put on goggles!

7. Turn out a spark plug.

8. Verify the turned-out candle with the ID card given below is will help at an assessment of the general condition of the engine.

Coal deposits

Symptoms: Availability of soot indicates reenrichment of fuel and air mix or weak intensity of a spark. Causes admissions of ignition, complicates start and results in instability of operation of the engine. Recommendations: Whether check the air cleaner is hammered, whether fuel level in a float-operated chamber is not too high, whether the air gate is jammed and whether contacts are not too worn-out. Try to use candles with longer insulator that increases resilience to pollution.

Normal state of a candle

Symptoms: Gray-brown color and easy wear of electrodes. The Kalilny number of candles corresponds to type of the engine and its general state. Recommendations: When replacing candles establish candles of the same type.

Oiling

Symptoms: Oiling of a candle is caused by wear of maslootrazhatelny caps. Oil gets to the combustion chamber through the worn-out directing valves or piston rings. Causes admissions of ignition, complicates start and results in instability of operation of the engine. Recommendations: Perform mechanical recovery work and replace candles.

Peploobrazovaniye

Symptoms: Soft brownish color of adjournment on one or b
