Last weekend I did a coolant drain to replace the upper and lower hoses, water pump and t-stat for pm. The water pump pulley had a slight wobble so I’m glad I decided to do it. All Cummins parts from Geno’s, the past couple days the temps on the engine and trans have been creeping up higher each day, today when I got home and parked the trans is reading almost 187 at idle, I’ve never seen it over 175 towing at 80 mph. I bled air, ran it to temp after the swap and had good heat after it was up to temp. Just weird, has anybody else had similar, I’ve done a search and not really seeing anything.
