I'm new to the 7.3's, and I just picked up a bone stock 95' 250. I notched after long 100 mile trips my temp gauge never gets passed the "N" in "normal" on the stock cluster, I have multiple friends who there trucks run way warmer. Is it possible to have my thermostat to be stuck open? And how bad is it if it is stuck open? I am starting to think more and more about it and its my only truck so I'm kinda worried... I work at advanced auto while I'm in school right now so I know I can order/buy the parts.. I am putting a 4" diamond eye turbo back and a TS 6 pos. chip this weekend.. It already has a k&n filter. I know my vacuum pump is going out cause my brakes will stiffen up sometimes. Can that course my issue?
