Engine Compartment Electrical Connector Cleaning and Maintenance Package

Technicians disassemble various electrical connectors in the engine compartment, using specialized cleaning supplies to remove internal oil, oxide layers, and dust. After protective treatment, the connectors are reinstalled. This package resolves issues caused by connector oxidation, such as intermittent circuit breaks, abnormal sensor signals, occasional vehicle fault codes, and unstable idling. It also slows down the corrosion and aging of metal pins, reduces the risk of short circuits in rainy or humid environments, and is suitable for electrical maintenance and fault pre-treatment in older vehicles, significantly reducing the probability of subsequent electrical failures.
