I just had my cooling fan replaced with the TSB. Here's the problem: when I had my old fan, the stock temp gauge would sit between N and O. Now it sits between M and A with the new fan. Nothing has changed except for the new fan and motor that Ford installed. What do you guys think? I noticed something too. It looks like the new fan only has a high speed motor. Is this true? I know the old one had a high speed and a low speed? Is there a change between fans? Could there be something else wrong?
