    Recently we bought a 2001 expedition 36 with a cummins 260 /5 spd with 30000
    miles, it ran good at sea level where we bought it. When we brought it home
    to Colo. we found it needs help getting up the hills. Mt, Vernon canyon was
    25 Mph and it was hot before we reached the top, at the summit we stopped
    and it cooled right down. The first time we were towing our geo tracker (toad)
    so I ran it again without the Geo, same results.
    Our old Gas 454 would run 40- 45 mph towing the geo on the same stretch of road.
    Could it be the turbo is not working? I have tried the disconnecting battery to
    reset the computer, The air cleaner looked a little dirty. so I ordered a new
    This is our first diesel and so far not happy with the performance, love every
    thing else its a keeper (I think
    Does anyone have any suggestions what to try next?

    My experience with diesels is that they don't have power change the air filters and fuel filters. It seem's strange that it would overheat. Make sure the coolent level is full. My 275 Cummins never overheats no matter how hard you push it. The Cummins has more torque than the gassers so it should take the hills better. If the filters don't help you might have to take it to a diesel mechanic. :question:

    Thanks for the comeback, Tinkerer
    The fuel filters was supposed to been changed less than
    2000 miles ago. The new air filter is on it's way. I'll
    might have to take it to a shop for a physical.

    Do you have an exaust brake? If it is stuck closed that can cause it.
    Good luck
