五菱赛欧通用水温传感器F01R064916，稳定可靠更换首选

Wuling Sail universal temperature sensor F01R064916 installed on the engine cooling system radiator or block waterway; monitors coolant temperature in real time and transmits signal to the ECU to control fuel injection, ignition timing, and cooling fan on/off. This sensor is a direct OEM replacement for Wuling, Sail, and various generic models; installation difficulty is low; approx 20-30 minutes; requires draining cooling system and replacing gasket. If engine starts hard, idle is unstable, temperature gauge fluctuates abnormally, or cooling fan runs continuously, sensor signal may be off; replacement restores normal temperature control.
