Summerization went great on the driveway. ran aprox 25 minutes all told. Dropped it it today and temp started to climb past 200. Replaced both impellar and tstat and still going up. checked the new tstat in a pot and its opening. got another tstat and installed this and still shooting up. Finally pulled the tstat and running without and temp is at 135 not ideal but wont kill the weekend. Any one with a great idea. 02 outback ls carb. thanks
