The engine temperature gauge in on my dash is not working anymore. Does anyone have any suggestions? Also, does my thermostat effect that gauge or is the thermostat just for the heater and so on...
Thank you in advance!
Assume 1993 Ranger
What engine?
There were 4 models in '93
On the engine will be a temperature SENDER, not to be confused with a temperature SENSOR(2 wires)
SENDERs have 1 wire connected
They are at different locations for each engine
But if you can find the SENDER then remove the 1 wire connector
Get another wire and connect it to the SENDERs wire
Ground that wire, to engine or Battery negative
Turn on the key, leave engine off
Watch the temp gauge, it should go to full HOT with that wire grounded
If so then wire and gauge are good, replace SENDER
Thermostat controls coolant circulation thru the radiator, so no it won't cause no temp to show on gauge.
Low temp yes, or high temp yes, but no movement at all, no
