Webasto leak
Like lonestar I just finished replacing all my engine and Webasto Coolant hoses. One day into a trip I see coolant dripping under Webasto area. Looks like maybe the short pipe coming out of the back end of the Webasto unit may have pinhole? Did notice some surface rust where pipe nipple joined the Webasto body which I cleaned up during the repair.
To continue travel I closed the Webasto in and out valves and opened Webasto bypass. Will work on It after trip when back in port.
Question for trainer (or anyone) do the Webasto units tend to corrode from inside and leak. What is recommended repair? Can I clean it up and tig mig or braze it, or a new housing? There’s always JB Weld. I fixed a pinholed oil pan on a junker 93 Continental with it and it ran 5 years until totalled.
Headed to Yellowstone, Durango, and Santa Fe.

David, the Webasto heat exchangers are long lived units but they are steel metal which can corrode. Your leak to the outside may be fixable which is much better leak than leaking into the exhaust system. Fix it anyway that suits you and you are done.
New exchangers are not terribly expensive and might be sourced from a salvage source.
All the best in your repair. Enjoy your trip.
