Dave and Jaime,

Look at my post # 18 above in this thread for a way to mount bushings which will possibly lessen the chance of a leak caused by excessive vibration/jolting on the radiator tab that connects to the all-thread rod that goes to the frame. Photos are included.

Again from recollection of prior discussion, the bracket itself wasn't the issue, but some problem w/tank welds. I could never figure out why that wasn't repairable. If you can weld pieces together, then why not a weld repair over weak welds? I can do that w/steel, but don't know that much about welding aluminium.

I think when the redesign of the radiator came about, they took a look at the whole design and went hella-strong throughout, thereby buttressing the mounts and adding bushings so as not to have to revisit replacements in the future. This was a lawsuit tween WRV & Radiator Specialties or at least threat of one, and RS coughed up 100 or so replacement radiators for WRV to dole out as problems arose.

IIWM and I had the OEM radiator, I'd do the bushings and watch my coolant level.

FYI- Mexican friend suggested a couple cups of ground black pepper in the coolant. Apparently that's a local favorite and know to stop leaks in the right circumstances. Or if you want to spice it up a little more, try cayenne.

All - Today I installed the rubber bushings on my radiator, with 25,230 or so miles, hope I don't have troubles. It was some work, but not bad, and I am glad I did it. It took about 4 hours maybe a little less, with me by myself. I copied the instructions and pictures above and kept that as a reference. I have made up another set of the washers/bushings and will have them with me at Quartzsite for sale, with the threaded rod, it would be around 50 bucks. I even have some nylock type 1/2-13 nuts which I can throw in.
