Gotta love that A-hole Pro-Driver, the sites "expert". Calls the Cummins cumapart, says he only drives Cats... last time I checked, the Cummins was the most reliable longest running engine made for a pickup. I haven't seen a Cat in a pickup yet! Then he tells the guy that his radiator is history when in fact the whole problem was just cleaning off some bugs,dirt & leaves from the front of the radiator. The "expert" was telling this guy to pop all his freeze plugs to flush out his system! When in fact all it needed was to hose off the front of the radiator, it nows runs at 190 degrees! LOL
