Engine wiring harness maintenance and failure hazards
The internal part of the engine wiring harness is generally composed of multiple strands of copper cord, and the outside is covered by plastic. The engine is like the human heart, and the wiring harness is the human muscle. Irregular tendons and veins can damage health and even cause disease. Similarly, the failure of the line will affect the performance of the engine.
Harm of engine wiring harness failure
The wiring harness has been working in a high-temperature engine compartment for a long time. The surface of the wiring harness will crack and fall off, and the exposed wires will cause leakage. The wiring harness interface will be oxidized and corroded due to the mixing of moisture and impurities in the engine compartment, and will also be loose due to bumps, resulting in poor contact. The most serious consequence of aging lines is to cause spontaneous combustion of vehicles.
How to maintain the engine wiring harness?
Do wiring harness maintenance regularly:
Harness maintenance usually uses a harness protector. Its working principle is to form a protective film on the surface of the engine wire/battery connector and the harness to isolate moisture and avoid oxidation. Because the spray itself has the characteristics of high voltage resistance and insulation, it can also delay the aging and cracking of rubber and plastic pipe fittings in the engine room, and prevent electrical leakage caused by aging of the wiring harness. In addition, the sprayed protective film is not easy to stain, and it is easy to wipe to keep the cabin clean for a long time.
Precautions for spraying protective agent on wiring harness:
1. Clean the engine compartment. Remove the dust generated by engine operation and sludge dirt caused by oil evaporation.
2. Rinse and dry with low pressure water. Never use a high-pressure water gun when cleaning. For those vehicles that have a long service life and have not been able to maintain the wiring harness regularly, low-pressure clean water flushing must be cautious. The safest way is to go to the repair shop and use a professional dust removal gun for cleaning.
The role of engine harness maintenance
1. Reduce circuit impedance, prevent oil accumulation, and improve system circuit efficiency;
2. Super permeability, slow down the aging of the wiring harness, and can effectively repair the line cracks;
3. Unique flame retardant performance, which improves the high temperature tolerance of the vehicle and reduces the chance of spontaneous combustion of old models;
4. A protective film is formed on the surface and plugs to isolate water vapor, resist oxidation and rust, and make the engine look like a brand new one.
