I am having an issue with the water temperature on my 92 Ranger.
Here is the background:
Previously, the temp. gauge would fluctuate drastically, the engine never came up to temp, and there was no heat. Close to the end of our cold season, I replaced the thermostat and heater hoses. Also, ran Prestone radiator flush through the system and back flushed the heater core separately. This seam to fix the fluctuation in the temp. and the lack of heat.
Now that it is getting cold again, I am noticing a different problem. The temp. gauge will only get barely above the "C," and there is a small amount of heat coming from the heater. I assume the low heater temp is due to the low engine temp. Is it possible the thermostat has gotten stuck open, or is there some other problem?
Thanks in advance for your help!
