Subject:      Re: Steel coolant pipe repair ideas
Content-Type: text/plain; charset="us-ascii"; format=flowed

Shawn, If you have any, standard 1.25" copper plumbing pipe is exactly the right internal diameter to slip tightly over the cut ends of the VW coolant pipes. I had to cut down the steel coolant pipes in my 84 Westy for an engine conversion, and like you, was concerned about leaving them without some kind of flare or bead at the ends. I cut a couple narrow rings of the copper and slipped them on the steel lines with lots of JB Weld... forms a good strong bead. No leaks in 20K+ miles anyway. best, Robert H 84 Westy "Busaru" - about to go into winter hibernation <www.people.cornell.edu/pages/rdh24/vw/index_vw.html>
