Check and replacement of spark plugs and ignition module

It is necessary to replace spark plugs only on cold or slightly warm engine. The reversing of candles on the hot engine can entail damage of a carving to a head of cylinders.

Socket and bolts of fastening of the module of ignition of the 4-cylinder engine

Socket and bolts of fastening of the forward module of ignition of the V6 engine

Socket and bolts of fastening of the back module of ignition of the V6 engine


 PERFORMANCE ORDER

  1. Switch off ignition.
  2. On models with V6 engines remove a decorative cover of the engine.
  3. Carefully separate the socket (ы) module electroconductings ignitions (it) and turn out bolts of fastening of the module (it).

At removal of the back module of the V6 engine previously it is necessary to separate the socket of electroconducting of the MAP sensor (see an illustration the Arrangement of components of a control system of the V6 engine).

  1. Remove the ignition module together with rubber consolidations from spark plugs and turn out spark plugs a candle key, trying not to incline it.
  2. Estimate a condition of spark plugs, check their interelectrode gap. If necessary correct possible malfunctions which it is possible to judge on a condition of candles (see the table below).
  3. Grease a carving of candles with means of Molycote 1000 or similar. Rubber consolidations grease with Krytox greasing.
  4. Establish new spark plugs and tighten them with demanded effort.
  5. Establish the ignition module with rubber consolidations, tighten bolts of its fastening and join the socket (ы) electroconductings, previously having cleared contacts (for example, Kontakt 61 spray).
  6. On the V6 engine after installation of the back module of ignition join the socket of electroconducting of the MAP sensor. Establish an engine cover.

Coal deposits

Symptoms: Availability of soot indicates reenrichment of a fuel and air mix or weak intensity of a spark. Causes ignition admissions, complicates start and results in instability of operation of the engine.

Recommendations: Whether check the air purifier is hammered, whether fuel level in the poplavkovy chamber is not too high, whether the air zaslonka is jammed and whether contacts are not too worn-out. Try to use candles with longer insulator that increases resilience to pollution.

Zamaslivaniye

Symptoms: Zamaslivaniye of a candle is called by wear of maslootrazhatelny caps. Oil gets to the combustion chamber through worn-out directing valves or piston rings. Causes ignition admissions, complicates start and results in instability of operation of the engine.

Recommendations: Perform mechanical recovery works and replace candles.

Overheat

Symptoms: Porous, white insulator, erosion of electrodes and absence of any deposits. Leads to reduction of service life of a candle.

Recommendations: Whether check there corresponds to requirements of Specifications kalilny number of the established candles, whether the corner of an advancing of ignition is correctly exposed, whether too poor fuel and air mix moves, whether there are no leakages of vacuum of the inlet pipeline and whether valves are jammed. Check as level of a cooler and whether the radiator is corked.

Too early ignition

Symptoms: Electrodes are melted off. The insulator has white color, but can be and is polluted owing to ignition or hit admissions in chambers of combustion of extraneous particles. Can lead to an engine exit out of operation.

Recommendations: Check kalilny number of the established candles, a corner of an advancing of ignition, quality of a mix (whether it is not too grown poor), whether the system of cooling is corked and whether the greasing system normally functions.

Electrocarrying-out luster

Symptoms: The insulator has yellowish color and the polished appearance. Speaks about sudden temperature increase in combustion chambers at sharp acceleration. Usual deposits are thus melted off, taking a form of a varnish covering. Leads to ignition admissions at high speeds of movement.

Recommendations: Replace candles (colder, at preservation of a manner of driving).

Short circuit of electrodes

Symptoms: A waste of products of combustion gets to interelectrode space. Firm deposits accumulate, forming a crossing point between electrodes. Leads to ignition refusal in the cylinder.

Recommendations: Remove deposits from interelectrode space.

Normal state of a candle

Symptoms: Gray-brown color and easy wear of electrodes. Kalilnoye number of candles corresponds to type of the engine and its general condition. Recommendations: At replacement of candles establish candles of the same type.

Peploobrazovaniye

Symptoms: Soft brownish color of adjournment on one or both electrodes of a candle. A source of their education are applied additives to oil and/or fuel. Excessive accumulation can lead to isolation of electrodes and cause admissions of ignition and unstable operation of the engine at acceleration.

Recommendations: At fast accumulation of deposits change maslootrazhatelny caps that will prevent oil hit in combustion chambers. Try to replace fuel brand.

Wear

Symptoms: A rounding off of electrodes with a small congestion of deposits on the working end. Color normal. Leads to difficulty of start of the engine in cold damp weather and to fuel consumption increase.

Recommendations: Change candles on new, the same type.

Detonation

Symptoms: Insulators can appear chopped off or burst. Also inaccurate equipment of adjustment of a candle gap can lead to damage of an insulator. Can lead to damage of pistons.

Zabryzgivaniye

Symptoms: After ignition admissions during a long period of adjournment can be loosened at preservation of working temperature in the combustion chamber. At high speeds of adjournment in flakes come off the piston and stick to a hot insulator, causing ignition admissions.

Recommendations: Replace candles or smooth out and establish into place the old.

Mechanical damages

Symptoms: Can be caused by hit of extraneous materials in the chamber of combustion or arise at piston blow about too long candle. Lead to refusal of functioning of the cylinder and to piston damage.

Recommendations: Remove from the engine extraneous particles and/or replace candles.
