Standard Ignition Engine Coolant Temperature Sensor P/N:AX54
Track engine coolant temperature accurately with the Standard Ignition Engine Coolant Temperature Sensor MC1416. This sensor reads the temperature of the engine coolant/antifreeze mix and sends that signal to the vehicle's control module and gauge, which use it to manage fueling and warn of overheating. It's a direct-fit OE replacement specifically designed for Harley-Davidson motorcycles, dropping into a broad list of 1999-2009 models spanning the Road King, Electra Glide, Softail, Dyna, and Sportster families. See the Buyer's Guide tab for the full 54-application list.
If a failed coolant temperature sensor is the cause of erratic gauge readings, hard starts, or fueling issues, this replaces it; diagnose the cause before replacing. Country of origin: Mexico.
