Installed the pulley today. only thing i notice is my truck runs 20* hotter now. i have a 160* thermostat, and the gauge on the dash would read 175-180, now it reads 185-195. anyone else notice this after instaling the pulley? also would installing electric fans bring the temp back down?

 

well that is because it sends less power that way with the different pulley and you didnt tell any difference in even highway power or anything??
