well, that didnt happen. Still runs between 220-230F during the day with the A/C on - ambient temps above 110F. Good friend of mine Nethergoat on here is having identical problems with his koyo. We BOTH had the bleeder screw problem within one week of each other as well, Coz wont take the koyos back if they are used.. I'm out 480$.. oh well.. lesson learned, I wont be shopping at Coz anymore.. sucks cause they are local, and im all about supporting local causes.
