Found a small leak on the lower right side of the radiator looks like its inside the area of the rubber mount. I actually see what looks like silicone sealer ooozing out of the mount. My question is it as easy as it looks to drop it, jack up the coach, remove all hoses and lines,remove the lower mount bracket and it drops out or is there more to it, the service manual I believe says I have to remove the fan shroud. Also any thoughts on repairing, probably a 40 year old radiator, or go ahead and get a new aluminum one. What says the think tank? Thanks in advance.

Pulling the radiator is pretty straight forward if you can get it high off the ground. Once you pull it I would take it to a radiator shop so they can check it out for corrosion. If just has a hole rubbed in the tank it is a cheap fix. If the core is getting thin from corrosion then you will have to decide between a new aluminum or high efficiency copper/brass re core. I went with copper/brass. Many here like the alum.

Took mine out the bottom in the driveway on a very hot day (sweat and bugs). Yes remove shroud. Spray cooler lines in advance so you don't kink and have a good selection of tools and flair wrenches. Use a floor jack under the U core support to gently lower assembly down. I recored mine. I like brass cores when the engine is cast iron, aluminum radiators on aluminum engines. I'm old fashioned.

Skip,
When Ken Frey and I were going over Double Trouble doing the final prep for our first tour of the USA we noticed that there was some
corrosion on the fins so we pulled the radiator out and had it flushed, pressure tested, and repaired (leaking tubes plugged at both
ends). It worked fine, however, when I was heading to KenH's home in Americus I crossed a set of railroad tracks at too high a speed
and the front end damn near went airborne. As I was pulling onto Ken's ramp he noted; "you know you've got water pouring out of the
radiator?" I got out and sure enough it was. We removed the transmission cooler that was held to the face of the radiator with
plastic thru ties like this:
http://pitstopusa.com/i-5077201-derale-electric-fan-oil-cooler-nylon-mounting-kit-includes-4-plastic-rods-clips-and-pads.html
HAD I KNOW WHAT WOULD HAPPEN WHEN I HIT THE RR TRACKS I WOULD NOT HAVE USED ONE OF THESE KITS!!!!
When I installed the cooler the bottom sat on the lower radiator mount supporting its weight. Even though the weight of the
transmission oil cooler was supported when I hit the railroad tracks it must have bounced and the plastic rods tore the horizontal
tubes. After removing the radiator Ken and I pried open a couple of the tubes and you could see that after almost 40 years in
service the tube wall thickness was paper thin.
Your options are:
A) Have your radiator repaired locally (leaking tubes plugged)
B) Have your radiator re-cored with a 4 row core with 14 fins per inch - VERY IMPORTANT!!!
C) Buy a radiator from one of the GMC vendors (listed alphabetically)

ii. New Griffen aluminum radiator: http://www.appliedgmc.com/prod.itml/icOid/585
2. Cooperative Motorworks: www.gmcco-op.com
i. Jim can supply the radiators listed above as well
3. Motorhome Enhancements / Gene Dotson

Let me say this. I do not know of anyone making a brass radiator. You can get cores and reuse the tanks on yours. I highly recommend the aluminum radiator which is what most of us use. It is built very strong unlike those cheap throwaway aluminum radiators used in new vehicles these days. I know of no one that has ever had a problem with one.
Jim K. (Applied GMC) or Gene Dotson (GMC Motorhome Enhancements) ought to be able to give you the shipping weight on one. They both ship them from them the manufacturing plant in NC all the time. Also one shipped by the manufacturer would have all of the appropriate packaging to put it on an airplane.
