Ok, finally got a long trip in, brake line shield functioned perfectly. put 3k on, I now have 126k on the 98 chevy chassis. The brake fluid didn't boil and back and front brakes both worked perfectly. Took it up a 8000 foot grade and when I got to the top brakes still worked perfectly. Had a 3100lb toad on the back. So, check your brake lines to make sure they do not pass close to your exhaust manifold like mine did.
Yes, I have stock manifolds, yes they get hot when I'm going up a 8000foot grade. Of course I don't go up a 8% grade at more than 35 mph and I'm lucky if I can go that fast.
Dang gone new fan clutch went out just as we climbed the last hill for home. Only 3k miles on it and the temp spiked to 220 and the clutch quit roaring I could hear when it went out. I hate changing that thing out. Good news is it the part is covered by warranty.
