Thanks for the info it has run like this since I got it

Yes 70 695 270 495 I stay local mostly Frederick and surrounding area

Don't know what temp it is going to but middle # is 180

Don't know what you mean by 68 or 70 no manual override

Ok I'll keep it to the wood thanks for the info

yes turns on and stays on till i level out thanks for the posts

that is as hot as it will get ac on all the way over the mountain but seems to warm to me

i have a 98 rd688s with an e7 350 replaced t-stat, fan clutch, oil cooler and radiator cooked out and rebuilt.

removed water pump looked ok the truck runs 180 but when loaded on a long pull it gets hot but has never overheated is this normal for macks or do i have a problem? any help would be greatly appreciated thanks
