Hi all, I recently installed the Flex-a-lite dual 13” electric fan set up in my 90 Blazer w/a stock 350 eng. The instruction sheet that was included was really not much help in explaining what the proper temp setting should be. Presently, I have a 195’ stock temp thermostat installed. I hooked up my OBD1 code reader to see what the ECM was seeing as far as temp goes. Right away I noticed that the stock temp gauge and the ECM temp were different. The ECM temp would show 197’ while the temp gauge would show 210-215’. Should I set the temp on the fan’s control box to what I see on the OBD1 reader or the gauge? Secondly, should the setting be that of the thermostat at 195’ or higher? I’m confused about what setting I should have the fan come on.
