    Temp bouncing around?

    So ironically on my way to the suby dealership to pick an oil filter up to do an oil change I noticed my temp gauge is going up considerably at an idle and returns to normal temp when I get going. My friend and I are thinking the thermostat just kicked it but I thought I'd see if anyone else had an idea before I drain the damn coolant to check. Thanks!

    If the thermostat failed you would be running hot all the time. I would check to see if your fans are coming on. Next step would be burping the coolant system. Just a worse case scenario: blown headgasket.

    Sounds like your radiator fan is out. Check your fuses. It has a normal fan fuse and a backup fan fuse. I had the exact same problem before and both the fuses were blown. If the fuses are fine then pop your hood and check to make sure your fan comes on when it enters the appropriate temperature. If not then maybe there is something mechanically wrong with it. It does not sound like the thermostat however. At least to me.

    Yeah check the fans. They kick on when the car is stopped or moving very slowly so the radiator can get adequate flow for cooling. They turn off when you're moving since air flows naturally at that point.
