I actually have a question about the lower radiator hose o-ring, and I am not sure where to put it. It looked like the other posts of the subject were in the smoke screen section, so here it is. I bought a dorman 926-160 o-ring, but with no matter how much force I exerted on it I couldn't get it to slip on to the radiator. I am 6'4" and 220, so I am not a small guy. I stuck my old ring back on and it is still leaking. Is there anyway that o-ring is too big? Was I just not lining it up exactly right? It seemed to have a hard time wiggling into that little groove where the o-ring is supposed to sit in the rad hose. Attached is a pic. The dorman part is considerably larger than the smaller one that came off the truck.
