Dear Paul

hmmmmm  thank you for the reply but you are wrong. It will get to the
temp of closed loopin about 3-5 min. The fan should not come on even
at low speed until the engine is 212 degrees F (100 degrees C) which
takes about 15 minutes at idle on a 90 degree day (32 degrees C). I
have a real anomally with this one. The interesting fact of the fan
coming on 3-5 min is that it coincides with the transition from open
loop to closed loop operation. I think somebody in the process of
installing a stereo in an otherwise fine little car may have reversed
polarity. The factory radio was smoked. The relay output card for the
cooling fan looks okay. I have yet to pull the PCM to see if they let
any smoke out of the things in there.

Thank you and any help will be appreciated,
Andy
