The coolant temperature switch is on the left side of the radiatorIt has 2 wires going to itDisconnect the switch & check continuity between the 2 terminalswhen cold (up to 150F or 65C +/-8F) there should be no continuity / infinite (or very very high) resistance through the switchFrom 180F /82C (+/-3F) there should be continuity / very little resistance through the switch
