Just what the title says. I'm looking for directions from the shop manual for thermostat replacement on a 2.0L GXP. I pulled mine out of storage yesterday and drove it. Temp went to 210, then fell abruptly to 165. Then went back to 205, then to 180...then leveled at 198 where it usually runs, until I would get on it, then it would climb to 205-208 again. And before any of the newer people suggest a WP, I've already had mine done about 25k ago. No white smoke, so it's not burning it... I had this issue last year, but it wasn't as pronounced. It would get up to 201 and then fall to 190 and would fluctuate between there.... Now the fluctuation is much more pronounced (between 185 and 210). So I'm guessing the thermo isn't opening all the way.
