Well that project is complete! Yes, duxthe1, I found that hidden nut on the back side of the bolt. I turned for a bit and saw that it was not extracting so I went huntin'

engatwork, yeah that tube ended up as it was before I started - not really 'attached' up under the coolant pump but secured into the AC unit. I tried to get it to stay in the hole but it just didn't want to. Interesting that they would route the 'leak' into the AC compressor. Can you educate me as to why they would?

I kept thinking that I'd use a piece of cardboard against the radiator but for whatever reason it didn't happen. No damage as I worked slowly and carefully but it sure is a tight area to work around! You know, first time doing something always takes me two to three times longer than doing it the next time. To me that's what's so neat about these old relics, they are classic and built to last as long as they are maintained. Keep them long enough and we get to do some of the work again!

One other thought here, Pelican should make a note about the differences in the W124 models and how they come apart for this belt tensioner pulley replacement because I was lost on some of the instructions in their instructional article. I think I might be able to add my own thoughts at the end of the article, come to think of it (CTTOI )!

Thanks for the replies here on this little bit of maintenance on the 124, she's a fine piece o' history
