Looking for radiator for 03 Diplomat


Recommended Posts

I have developed a leak in the tank on the tranny cooler. I have had it welded twice so that isn't working very good. It is getting a crack in the tank in the same place and the weld isn't holding. I don't see any stress on it in that area but maybe the vibration is breaking it.

 If anyone knows of a source for the older Monaco parts please let me know. 

The radiator is 12" x 22" and mounts on top and r side 

I could try another weld job but would like to replace it.

Thanks for any help

Jim,

It would be easier and maybe even cheaper to have a shop like CG&J or Source Engineering make you one based on the one that you have now. Take dimensions, mounts and opening locations, etc. then send them an email to those two shops to see what they can do.

Just a followup on the transmission cooler radiator leak. The tank developed a leak for the second time, first time was 2 years before, I removed it and had it tig welded at a machine shop and it looked good but it developed another leak after around 400 miles so filled up with tranny fluid @$52/gal and limped to my destination. Took it off again, getting pretty good at this, took it to a machine shop and explained where it was splitting and that I wanted a patch welded over the corner where it was leaking. They Tig welded the crack then welded a patch over it. I think it will hold only time will tell.

Thanks for all the helpful replies but I was forced to get it done quick so the patch job. 

Thanks
