:tools1: It was almost a year to the day that I had my thermostat replaced (under Warrantee - I got it back Oct 20th 2006) Saturday I took it again for the same thing. It may not take that long to actually stick open, but here in Florida it dosn't get cold enough to affect it till now. THe first time it was around 17,000 miles and now about to turn over 33,000 so it is about even in that respect
