hey guys, you have to be careful with reversing the airflow by reversing the wire polarity, because a lot of these motors are designed to rotate the one way. you can burn them out by making them rotate in the opposite direction. thats why davies craig ones are reversed by reversing the fan not polarity.
greg - if you stick your hand in front of my grill you would swear the fan is blowing not sucking too. but when you compare the flow on the engine side vs the grill side you realise that it is actually sucking as it should. as eric suggested, check out whether the donor car for the thermofan had it mounted engine side or grill side to determine the operation it was designed for. good luck for the new 1600 project :) andrew On Sun, 25 Nov 2001, Jon Ovington wrote: > Some fans for example aftermarket Davies Craig can easily bun unbolted and > turned around to suit 'blowing' or 'sucking' for in front or behind the > radiator. > > However, Greg seems to have said, is thermo blows hot air out!
