Engine Coolant Guage.....Fluctuating?
A couple days ago, I noticed my Engine Coolant Guage on the cluster was not moving at all until warmed up and driven a few miles. Then it would move from cold to not even half way all of a sudden and fluctuate slightly. After turning truck off for a few minutes and turning it back on, the needle would be all the way down at cold again.
Today I changed my thermostat and the needle moved up after letting truck run for 10 minutes. I know these 3.0 motors take a long time to warm up (no i dont have an efan). I had good heat after being wamred up.
Is the thermostat sending unit the same as the Engine collant temp. sensor? I replaced that a couple years ago.....maybe that is messed up again.
I'll be driving the truck tonight and will watch the needle.......
