Post your file here...
1. Which type of Fan you have? With stages, or is linear...
2. At which temp. (coolant, through diag!) the Fan starts to spin at all and at which temp. the fan is at highest speed?NO PASSWORDS FOR ANYONE, EXCEPT THE RECIPIENT OF THE FILE !!!

97/98 is not too high temp. for highest stage of the cooling fan, my own car starts at 102... Originally Posted by joker01
