did a double VE swap, my friend and i did both of our motors this week, we started his up first,after 5 minutes the fans came on, then they never seemed to go off even after 15 minutes running. he used his DE thermo switch, and i used my ve thermo switch
****when i say thermo switch, it is the one behind the intake manifold next to some valve
same thing when i started up mine after 5 minutes, fans came on then would not shut off
need some feed back

He can make 200,250 or even 300whp! Because at the end of the day, He's not going no where but up and down Liberty Avenue stuntin for the rest of his fellow Indian friends!
AC on? It sounds like the ECU might be in fail safe mode. If it thinks the temp is too high, it will turn the fans on. You did hook the ECU temp harnes up, right?

also you may have had lots of air bubbles in the system at that point and the ecu thought the motor was hotter than it really was, causing the fans to stay on. remember, there is a bleeder screw on the top of the thermostat housing.

both cars do the exact same thing , no overheating at all,
something funny happens with the needle, with the old motor, when warming up, the needle wil go up slowly<temp guage>, but now it will warm up for 5 minutes the fans will come then 2 minutes later the needle will shoot the the middle and stay there, well i mean not the middle just a little under the middle
i know your needle should start moving before your fans come on

use the de coolant sensors bro. the japanese ones work differently....the ecm reads inputs in different values. de sensors will fix the problem. the imperative one is the two prong one that goes to the ecu. the one for the gauge will correct the funny gause problem.
