Background: '85SE 2M6 3.4l
With the installation of my 3.4PR ( with new water pump) I replaced the temp sensor ( by the distributor) and installed a Rodney Low temp 200*-210* Fan Switch (by thermostat), installed new thermostat. 195*. & rewired the Temp Gage/Over Temp light in dash panel.
Tests performed: Fan switch grounded... turns on Fan.. Temp sending wire harness ground test Battery power on. left side Temp Light on, Right side Temp Gage pegs in red ......All Good!
All wires attached.... Ignition "On".... Over Temp Dash Light on. (bulb check)
Start engine; coolant comes to temp .....gage hits 240 or so thermostat opens...(Hot water to front radiator and return hose).. gage continues to Red Zone. Fan never kicks in and Over Temp Light never comes on ! Coolant Fluid never flows out.
Bad sensor from TFS ?? Gage side of sensor only is there a resistor I am missing?
