Eric,
To relay to your suggestions:
1 The fan shroud is original and complete. I had actually thought about cutting and attaching mending plates to give me better access, but have not done it.
2 The fan is complete and not missing any blades.
3 I am pretty sure it is installed correctly, but will verify once I get ready to leave tomorrow
4 The Fins appear to be clear
5 The belt tensioner appears to be ok and both belts are brand new
6 The black plastic is still in place around the outside of the radiator if that is what you mean by block off panels
7 I will have to check or just replace the regulators.
8 I am hoping that the water pump is still good since I just replaced both belts, but that may be an issue
9 The Fins look decent, not new but decent
10 As far as a internal blockage I am leaning in this direction, I at least plan to flush and refill the system.
RPM's may have also been part of this issue, When I started up the grade I had no idea it would be that long or 8% ( the sign is on the uphill side). I was dropping gears, but sooner would have been better, and at some point I only had about 30% of the power since it was derated. and there was no where to pull over.
Since I am still at the campground, with ify wifi and no cell signal, can someone tell he what Antifreeze I will need to get, and how much the system holds. If wifi holds out I could at least get that on the way.
Thanks for the help everyone, I as still waiting for that perfect trip where absolutely nothing goes wrong!
