A little bit more help on the temp sender. The gauge sender will have only one wire and be in the coolant flow somewhere before the thermostat. You can determine if the sender of gauge is the culprit by taking the sender wire to ground. Do this with a jumper since the engine will have to be running (ignition power to the gauge). If the gauge goes fully to high temp reading, it is the sender at fault. If the gauge doesn’t move, look for power at the gauge (marked with “I” ) or a broken “S” wire to the sender.
The gauge will have three terminals l, S, & G, ignition, sender , & ground. With power on I, ground the S terminal and the gauge should move to full scale.
