Hydraulic fan motor leaking '02 U320 Cummins ISM 450
We had a fairly long drive today, from Taos, NM to Denver, CO ... over the Raton pass and up I-25 to Buckley AFB. Just a bit more than 300 miles and pulling some decent hills. Got fairly warm engine temps only once, but things got a workout. After parking at the AFB famcamp for about 45 minutes on a nice, new concrete pad Jeff noticed a small oil patch under the rear of the coach. It appears that the fan motor is leaking a bit. The threads that I can find concerning this issue all seem to involve coaches about 10 years older with engines different from ours ... don't know how much this matters.
Is there anyone who has had an issue with a year/engine closer to ours?? How urgent is this sort of thing? We will be making a loop from Denver to Yellowstone and back with some grandkids and would prefer not to be stuck along the side of the road.
