I own a 1989 dual fan iroc-z, I have replaced the fan switch and stat with jet chip product. The fan switch is the 200*/185* on and off model while, the stat is rated at 180*. The temp sending unit was also replaced at the same time. The problem is that the fan(s) turn on at about 227* and off at 218*. The measurments were taken with an external tool. What can I do to fix this problem? Until recently, the original fan(s) set up would turn on at 220* and off at 200*. Then the problem started. The fan(s) then started to turn on at about 230*. The fan switch, coolant, and temp sending sensors were replaced, with factory product,but the problem stilled continued. So thats why I decided to have the jet products installed. Again what can I do?


P.S. My car is all original except for the muffler. It is a flowmaster 80 series model. The engine is a 5.7 350.

its complicated, but the temp sensors need to be checked to make sure there putting out the right signal at the right time, if they check out then its most likly a problem with the ecm in that case maybe you can get an adjustable switch.
