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

Fig. 2.30. Removal of a tip 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, you make replacement of candles in turn.
On cars, since 2001, remove ignition coils.
Stream of compressed air clear the place around a candle that will exclude hit of dirt 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 a condition of the engine by their appearance. Pure, white, without raid the insulator of spark plugs testifies to too poor fuel-air mix. It can also indicate that a candle of too "hot" type (heat from the central electrode is taken away slowly). It is necessary to adjust composition of fuel-air mix or to establish the candle suitable according to characteristics for this engine.
Adjournment of a dry black soot indicates too rich mix.
If the raid the black, oily, so engine is worn-out, it needs to be checked and repaired.
If the insulator is covered with a light brown raid, then the composition of mix is optimum, and the engine is in good shape.

       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 spark power changes leads to decrease in overall performance of the engine. The gap has to conform to technical requirements always.

Fig. 2.31. Check of a gap between spark plug electrodes


Check a gap a wire template or the probe (fig. 2.31) . It is possible to adjust a gap a podgibaniye of a side electrode the special tool (fig. 2.32) .

Fig. 2.32. Correction of a gap of a spark plug podgibaniye of a side electrode special tool


Before installation of a spark plug in the engine check that the carving was pure and intact. If necessary clear a carving. Apply special antiprigarny structure on a candle carving.
Examine spark plugs on lack of defects. In the presence of cracks on the insulator replace a spark plug.
For a candle wraparound on the first several rounds use a piece of a rubber hose into which on the one hand insert the insulator of a candle. The hose works as the universal hinge to combine a candle with a carving opening. If the candle is rolled with a distortion, then the hose will be turned on the insulator of a candle, preventing damage of a carving. Wrap a candle on several 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
The recommended frequency: each 50000 km of a 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 coils of ignition are installed directly on spark plugs.

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