View Full Version : Possible Thermostat Issues?

09-17-2011, 10:19 AM

I'm new here, so sorry if this is posted in the wrong category.

Last week, I was warming up my 03 Outback, to change the oil, using a fake-a-lake in the driveway. After running the engine for 5-7 mins or so, I noticed the temp gauge had dropped back to its starting position (it was nearing operating temp before the drop). I cut the engine off, and wiggled the wires around the thermostat, to see if maybe I had knocked them loose. Still no change. Any ideas?

Thanks for the help in advance.

could be your gauge, try wiggling the wires on it, or check to se if there is a signal going to it with a voltmeter....not sure what it is ohms or what the value should be, someone may chime in, Also not sure how your dash is controlled that year which mdc unit.
