Enjoying candles are used on engines with diesel power supply. They are heating elements, the temperature of which can reach 1000 degrees. It is not necessary to contact the service center for replacing candles of incandescent at all, the owner of the car may well carry out such work with his own hands.
First you need to disassemble the external engine sheathing and remove the battery. The candles are screwed into the block of the power unit and a thick electric wire is suitable for each of them. It must be dismantled. The specific work procedure in this case depends on the brand of the car. For example, on the engines of the CDI family, you usually have to remove several decorative covers, part of the intake manifold and a boost system.
After removing the wires with a suitable key, the candles of incandescent are unscrewed. Their seat should be carefully cleaned of contaminants that can penetrate the cylinders. Gently screw new candles, if necessary, a small amount of solidol can be applied to their thread. Should be twisted until it stops, after which the candle should be slightly tightened.
A high -voltage wire is installed on a new candle and a cap is put on. Before installing it should be carefully examined. There should not be any visually visible damage on the cap, otherwise the candle contact will quickly clog with dirt.
Testing candles of incandescent is carried out directly on the engine. Before checking them, you should stock up on thick gloves, with which you can protect your hands from thermal burns. For work, you will need a simple tester that must be installed in the resistance verification mode. One tester probe is placed on the power unit case, and the other on the contact of the candle. If the signal is absent, then it can be considered faulty.
After removing the candle contact, it is necessary to apply voltage from the plus terminal of the battery. Her body at this time should be on the weight of the engine. The serviceable candle will quickly heat up and the potassium tube will begin to glow. If the reaction is absent, then only replacement will help to fix the situation.
