Honda Accord

1 — the Candle head - Is equipped with the special elastic insert excluding a possibility of casual damage of the porcelain insulator at a candle reversing.
2 — the Dynamometer key - without being among obligatory tools, provides a reliable guarantee of correctness of effort of tightening of spark plugs.
3 — the Ratchet drive - Is used in a set with a candle head and a dynamometer key.

4 — the Extender - Depending on model and a complete set access to spark plugs can be limited by its auxiliary units in various degree therefore use of extenders of the corresponding form and design will allow to facilitate implementation of the procedure considerably.
5 — the Device for measurement and correction of interelectrode gaps of spark plugs - Is issued several types of this sort of tools - make sure that the tool is completed with the probe corresponding by the size to gaps of candles of your car.

If original candles after check of a state are established on the engine again, they have to be rolled strictly in former cylinders, - make the corresponding marking.

 PERFORMANCE ORDER

Symptoms: Availability of soot indicates reenrichment of fuel-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 the float-operated camera 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 the resilience to pollution.

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.

Symptoms: Oiling of a candle is caused by wear of maslootrazhatelny caps. Oil gets to the combustion chamber through worn-out guides of 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.

Symptoms: Soft deposits of brownish color on one or both electrodes of a candle. A source of their education are the 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 bystry accumulation of deposits change maslootrazhatelny caps that will prevent hit of oil in combustion chambers. Try to replace fuel brand.

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

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

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

Recommendations: Change candles on new, the same type.

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

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

Symptoms: Insulators can be chopped off or burst. Also inaccurate technology of adjustment of a candle gap can lead to damage of the insulator. Can lead to damage of pistons.

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

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

Symptoms: After admissions of ignition 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 the hot isolation center, causing admissions of ignition.

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

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

Recommendations: Remove deposits from interelectrode space.

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

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