On old coaches the plastic tanks or other wise items that are made of plastic deteriorate our tank was not leaking but it was a time bomb which would leave a mess going down the road or in your driveway, I was informed this by a couple crusty old guys no name mentioned that had this happen so I heeded to their knowledge and changed ours out, went from old plastic to a stainless steel tank rather than fabricate a new tank I looked on ebay and found a fuel tank that was the same OD as the plastic one and ordered it, had to tig weld a 1/4" T fitting on the bottom and cut a hold in the top (which would be the side for a tank) and bingo it was done here are some pictures of the old and the new tank. Thanks to those guys who did a walk around our coach! If you don't have a tig then silver solder would work or hire it out. If your coolent recovery tank has no fluid in it your bound to overheat at some point. Also you must leave the top cap loose so the recovery part will work, I cut a 1.5" hole and used a plumbing pipe stop to cover up the area where you would fill it but leave the cap on the fill loose. The diameter of the tank is 8" if you care to shop elsewhere but I used the same brackets that came with the plastic tank.
Great work! Thanks for the sharing.
I ordered mine a year ago because my plastic CRS 300 had cracked and was leaking.
I paid $190 for an aluminum replacement, raw finish, custom made dimensions to match the original one.
I’m almost ashamed of this, this thread just reminded me that I needed to get a more permanent fancy one… however, when I picked up the coach in California, I cut a hole in the screw top of the one gallon empty antifreeze bottle just enough to route the rubber overflow tube from the radiator into the lower part of the container . It’s worked great since then as the perfect expansion bottle. I suppose it’s time to update.
