Toyota RAV4>> Maintenance>> Check and replacement of spark plugs

Fig. 2.30. Tip removal with a high-voltage wire from a spark plug on cars till 2001


On cars till 2001, having pulled up and at the same time turning, remove a tip with a high-voltage wire from a spark plug (fig. 2.30) . Not to mix a wire to spark plugs, make replacement of candles in turn.
On cars, since 2001, remove ignition coils.
Stream of the compressed air clear a place round a candle that will exclude dirt hit in the engine cylinder after a spark plug reversing.
Turn out a spark plug.
If replacement of spark plugs is necessary, apply only the spark plugs recommended for this engine.
Examine spark plugs. It is possible to determine an engine condition by their appearance. Pure, white, without a raid the insulator of spark plugs testifies to too poor toplivovozdushny mix. It also can indicate that a candle of too "hot" type (heat from the central electrode is taken away slowly). It is necessary to adjust structure of a toplivovozdushny mix or to establish a candle suitable on characteristics this engine.
Adjournment of a dry black soot indicates too rich mix.
If the raid black, oily, means, the engine is worn-out, it is necessary for checking and repairing.
If the insulator is covered with a light brown raid, the structure of a mix is optimum, and the engine is in a good condition.

       PREVENTION
On cars since 2001 spark plugs with the electrodes covered with iridium are used. On such candles the interelectrode gap is not regulated.

Too big and too small interelectrode gap at which the spark capacity changes, leads to decrease in overall performance of the engine. The gap should correspond to technical requirements always.

Fig. 2.31. Gap check between spark plug electrodes


Check a gap a wire template or shchupy (fig. 2.31) . To adjust a gap it is possible a podgibaniye of a lateral electrode the special tool (fig. 2.32) .

Fig. 2.32. Correction of a gap of a spark plug by a podgibaniye of a lateral electrode by the special tool


Before spark plug installation in the engine check, that the carving was pure and intact. If necessary clear a carving. Put on a candle carving special antiprigarny structure.
Examine spark plugs on lack of defects. In the presence of cracks on an insulator replace a spark plug.
For a candle wraparound on the first some rounds use a piece of a rubber hose into which on the one hand insert a candle insulator. The hose operates as the universal hinge to combine a candle with a carving opening. If the candle is rolled with a distortion, the hose will be turned on a candle insulator, preventing carving damage. Wrap a candle on some rounds of a carving, remove a hose and further turn and tighten a candle a key.
On cars till 2001 establish into place a tip with a high-voltage wire, pressing it and at the same time turning before its accurate fixing.

       NOTE
Recommended periodicity: each 50000 km of run or 24 months.

       NOTE
The cover and rotor of the distributor of ignition equipped cars only till 1997 of release. The cars which were issued from 1988 to 2000, are equipped with contactless system of ignition.
Release cars till 2001 have high-voltage wires, and since 2001 of the coil of ignition are established directly on spark plugs.

On cars since 2001 establish ignition coils.
Similarly in turn replace other spark plugs.
