Is Engine Compartment Wiring Harness Maintenance Necessary?

[HenryLynn]

Automobile engine wiring maintenance is necessary. Here are the relevant explanations: 1. Wiring harness aging: The engine wiring harness inside a car is generally composed of multiple strands of copper wires wrapped in plastic. During daily driving, the engine compartment temperature is very high. When heated, the plastic covering will release plasticizers and other chemicals, which react with the internal copper wires, leading to reduced plastic strength and increased copper wire resistance. This ultimately causes the wiring harness to age and poses a risk of short circuits. Rubber hoses in the engine compartment are unsaturated polymer hydrocarbons, and aged rubber is also prone to oxidation, which can cause vehicle self-ignition. 2. Engine wiring oil contamination: Oil contamination on engine wiring significantly affects the engine's working quality and efficiency. This can result in abnormal vibrations, increased noise, insufficient power, decreased fuel economy, and greatly shortened vehicle lifespan. Therefore, for older vehicles' engines and wiring, regular maintenance is even more essential to extend their service life as much as possible.
