hmmmm i don't think it is your thermostat as those remain open when they break and your engine will get cold not hot. soooo..... I would say try bleeding the radiator like someone else said because it could have air in the system. But if it doesn't have air in the system then i am unsure and you may want to look into that water pump. __________________ custom dual exhaust,M3 front and rear bumper, 10.4 inch roof mount drop screen, Viper alarm system, DSII's rims, M3 Vader Seats, M3 Mirrors, Carbon Fiber CAI, Smoked Corners, Side Markers, Leatherz armrests, black grilles 225k miles and still the Ti goes on |
