福田五十铃水温传感器 1306350DL 42-045 直接替换原装位

Foton Isuzu water temperature sensor 1306350DL (OEM 42-045) designed for cooling liquid temperature monitoring, installed in radiator or cooling loop; collects temperature signal and transmits to ECU to precisely adjust fuel injection and fan operation. Direct replacement for original position; fits Foton Isuzu series; no modification required. Installation is low difficulty; about 30 minutes; some coolant drainage required. If engine starts are difficult, idle unstable, temperature gauge abnormal, or fault light on, sensor aging or signal drift is the cause; replacement restores optimal engine operation.
