Check of a condition of candle wires should be made regularly according to the schedule of routine maintenance of the car, and also each time at replacement of spark plugs.

In order to avoid a pereputyvaniye of wires at connection check each of them serially.

PERFORMANCE ORDER

Disconnect a wire from the first candle. For this purpose undertake only a tip (cover) of a wire and pull it, at the same time slightly turning. At all it is not necessary to undertake and pull for a wire.
Check internally walls of a cover of a tip on existence of traces of corrosion (as a fragile crust of white color). Again put on a tip a candle shaft. The tip should keep on a shaft rather hardly. If it not so, remove a tip and nippers carefully turn in the metal plug in it so that the last densely kept on a candle shaft.
Pure rags wipe a wire on all length, having removed from it all mud deposits and greasing traces. After cleaning of a wire check it on existence of breakdowns, прогаров, cracks of isolation and other damages. Do not bend a wire excessively as it can lead to its break.
Disconnect a wire from a distributor cover. Again pull only for a tip, instead of for a wire. Also as before check a tip on reliability of fastening on the plug and existence of traces of corrosion and other damages. Connect a wire to the plug of a cover of the distributor.
On one check a condition of wires of the remained spark plugs, watching reliability of fastening of wires on candles and plugs of a cover of the distributor after completion of check).
If replacement of candle wires is required, it is necessary to get the wires, suitable is concrete for the engine of your car. In sets of a wire offered on sale usually are already cut on length and are equipped with tips. Remove and replace each wire separately in order to avoid the wrong order of their connection (which observance extremely important for normal functioning of the engine).
Give screws of fastening of a cover of the distributor. On V8 engines for ensuring access it is required to disconnect vacuum lines of system of a retsirkulyatsiya of the fulfilled gases (EGR) and electric sockets. Delay a cover with the wires connected to it up, having separated it from the case of the distributor and put aside.
Now the begunok on the end of a shaft of the distributor becomes well visible. Carefully check it on existence of cracks and coal paths. Make sure of adequacy of the effort developed by a spring of the central plug and examine a nouse a begunka about identification of traces of corrosion and wear. In case of absence of confidence of condition definition a begunka replace it.

Begunok of the distributor should be checked on existence of wear tracks and corrosion, as is shown in drawing (in case of absence of confidence of condition definition a begunka, replace it).

If carrying out replacement is required, remove a begunok from a shaft and establish on its place the new. Begunok in a tightness is planted on a shaft and can be removed by a poddevaniye way any lever.
Begunok can be established on a distributor shaft uniquely. The begunok established in a tightness is equipped with the built-in directing shponka which at installation should be combined with a groove on the shaft end (or on the contrary).
Check a distributor cover on existence of coal paths, cracks and other damages. Attentively check plugs in a cover on existence of signs of corrosion and damages. Existence of insignificant deposits is admissible. Again, in case of absence of confidence of an assessment of a condition of a cover simply replace it. Before cover installation into place do not forget to put some a little silicone greasing on each of plugs. Track also correctness of installation in a cover of a coal brush (the central plug) - excessively wide gap between a brush and a begunok can be at the bottom of a burn-out a begunka and/or damages of a cover of the distributor.

Cases of the most typical defects meeting at survey of a cover of the distributor (in case of absence of confidence of definition of a condition of a cover, replace it on new) are given in drawing.

For cover replacement simply remove it from the distributor and on one rearrange from it candle wires on the prepared new cover. At all do not allow violation of an order of connection of wires!
Establish a cover on the distributor and fix it screws.
