diff should be 4.1:1 if they're factory, If it was me and I was running the old diesle motor to turn 35's I'd probably go to 4.56:1 diff gears.

Check your fan clutch, mine did the same thing, heated up at 100km up long hills. As soon as I got over them it cooled down again. $12 of clutch fluid and its been perfect
