IWIRE Coolant Temp Sensor plug 2008-2021 WRX/STI

The wiring for the coolant temperature sender on the Subaru can sometimes get damaged, corroded or melted. This repair harness is an affordable solution, especially compared to replacing the whole rear wiring harness. If your engine coolant temperature sensor or plug has failed, you may notice one of several symptoms: your temperature gauge doesn’t move, your engine overheats without warning, your radiator fans don’t switch on, or they don’t switch off.
