1. Original Equipment Adaptation for Toyota Family Vehicles, Zero Installation Threshold
As an original Toyota-spec solenoid valve (part number 32610-23330-71), it is fully compatible with the 4AT/CVT transmission oil circuit interfaces (such as M8×1.0 threaded interfaces) and wiring harness plug pin definitions (6-pin waterproof plug, meeting IP67 dustproof and waterproof standards to cope with daily car washing and rainy day scenarios) of family vehicles like Corolla and Levin. No modification to installation dimensions or adjustment of circuit parameters is required. After installation, it can directly achieve "plug-and-play" communication with the original vehicle's TCU without additional programming and calibration (the TCU automatically recognizes original accessories). The applicable models cover mainstream family configurations such as Corolla 1.2T, 1.8L Hybrid, and Levin 1.2T, 1.5L. The regular replacement working hour at repair shops is ≤ 1.5 hours, reducing the time cost of maintenance for family car owners.
2. Household-Level Durable Craftsmanship, Outstanding Cost-Effectiveness
The valve core is made of martensitic stainless steel (material: 4Cr13), treated by "ordinary quenching + precision grinding", with a surface roughness of ≤ Ra0.03μm and a surface hardness of over HV900. Its wear resistance meets the annual driving demand of 15,000-20,000 kilometers for family vehicles and can resist long-term scouring by hydraulic oil (ATF WS oil service life ≥ 60,000 kilometers); the coil uses polyester enameled copper wire resistant to 180℃ high temperature, covered with a nitrile rubber insulation layer, which has basic oil resistance and anti-aging properties to prevent short circuits caused by oil penetration in daily use. Through 1 million cycles of action testing (simulating a 10-year/150,000-kilometer household usage scenario), the failure rate is ≤ 0.8%, and the service life can reach more than 150,000 kilometers under normal use, meeting the "long-term durability" demand of family vehicles.
