Sweety- my fan was crap until i had to change the heater matrix, the old one was manked and blocked up, now flows sweet! but i think the by-pass valve is f**ked cos the best i can manage is, luke warm!
Mirrage- What temp dose your car run st, dose the fan kick in when ever you stop? When my fan kicks in If i've been sittin in traffic ect, i get a cold rush off water thourgh the system and my blowers try to freeze my nuts off......
