Although the replacement of spark plugs is included in the list of the simplest service operations, this work must be carried out strictly at a professional level. The fact is that the correct operation of the new spark plugs directly affects the level of fuel consumption. We often have to face when in the process of self-replacement of spark plugs in Kiev or any other city in the country, the driver puts candles in which the gap between the electrodes is not calibrated.
As a result:
- not all fuel in the cylinders starts to burn out;
- the detonation cycle of the air-fuel mixture may fail, etc.
Of course, this is not the only snag that awaits the master on the way to service the ignition system. In most cases, “home experts” do not take into account the fact that the seats of the spark plugs lead directly into the combustion chamber of the cylinder block. It is necessary to fall into any of the holes with debris (eg, scale or metal shavings) and the engine can literally “catch the wedge”, ie it will jam.
The conditions of the repair base in our service center can be compared with laboratory. Before dismantling the spark plugs, the entire space around the cylinder block is washed and blown out with compressed air. By the way, without an air pistol it is better not to approach candles at all.
Professional replacement of spark plugs
Renewal of spark plugs is regulated by the car maintenance passport. As a rule, candles change with a frequency of 30,000 – 100,000 km or even more, it all depends on the brand and modification of the vehicle.
Note that the weak point of many cars are high-voltage wires that attack the spark plugs. In the hands of an inexperienced master, the lead pads simply come off. Only a specialist knows how to safely remove the wiring.
The main difficulty in replacing the spark plugs is unscrewing the ignition. Private craftsmen make a big mistake when carrying out maintenance of the ignition system without applying new candles to the thread of graphite heat-resistant oil. When unscrewing the spark plugs dry, it often happens that the spark plug threads in the cylinder head cover simply break. Of course, there will be a car with a broken candlestick thread, but we don’t have to talk about the quality of the ignition system of such a car.
The new cylinder head cover is not cheap. The cost of replacing spark plugs for self-repair can increase significantly.
To unscrew the spark plugs safely, you must use a special spark plug wrench. Such a tool is not sold on the car market. Branded spark plugs are only available to specialized service centers. This tool differs from market stamping:
- increased strength characteristics;
- jewelry calibration of the sizes in a cap head.
Do not forget about the control of candles. The repair base of our service center is equipped with a test bench for ignition. Both the gap between the arc and the wick and the time of the spark are controlled. That is, we use only new and tested candles for maintenance.
What else do you need to know about the process of replacing candles in Kiev?
Possibility of full control of repair process allows us to guarantee the maximum quality of maintenance and high operational characteristics of new candles.
It is worth noting that worn-out candles can be diagnosed. According to the features of the soot and the color of the tip of the old candles, we can conclude how other functional departments of the ignition system work. In particular, you can get information about the quality of the fuel used and the accuracy of the time of the spark.
Based on these data, the car owner will be given subject recommendations for the operation and maintenance of the ignition system.
Another common problem for car owners is that many car models switch from one type of fuel to another (such as gasoline). Few people know, but for different types of fuel it is recommended to use a separate type of spark plugs. Ignition for gasoline and gas differ in geometric sizes and a profile of a candle head. They have different arcs and wicks, as well as different gaps between the ignition elements.
We assure that only highly qualified masters will be able to change the spark plugs, taking into account all the subtleties and nuances of the ignition system. At home, it is difficult to properly replace the spark plugs, as in a private garage is unlikely to find an expensive test bench and branded candle tools.
