Oasis radiator / blower unit .

Hi guys
Can anyone tell me if the wet bay radiator heat unit is the same part number as the other ones used in the Coach ?
ITR closed for the weekend. Radiator has sprung a leak in the copper header piping. Hidden behind wet bay board so son of a gun to access

They make a few different sized heat exchangers. Orientation of the pipes, mounting flange, and number of fans.

Wonder if you get it out...if it can be brazed and put back in...

If you fashion a pipe to temporarily shunt the supply/return lines...while you have the heat exchanger can buy you some time to see of brazing will work.

I was thinking the same thing.....take it to a radiator shop and get it repaired. First, I would price it out with ITR, maybe they warranty the thing????

Did the mounting position and hose connection stress the unit and cause a break? Maybe check before reinstalling for a stress free connection..

Good idea on seeing if a rad shop can repair. Just replaced the unit in my kitchen which was leaking internally. ITR charged about $ 220. For the new unit
I can likely jury rig a bypass to save the fluid draining down.
