长安之星悦翔福瑞达水温传感器3762020B2 直接替换

If your Changan Star, Yuexiang (Changan E), or Furuida experiences cold-start difficulty, rough idle, fluctuating temperature gauge, or check engine light on, this is typically a sign of aged or failing coolant temperature sensor. The sensor monitors coolant temperature in real time and sends signals to the ECU to control injection quantity and ignition timing for stable operation across conditions. OEM number 3762020B2; fits Changan Star, Yuexiang, Furuida and many models. Install only when cold, ensure sensor seal to the radiator is tight to prevent coolant leaks and misreadings.
