Looks amazing Wayne, I'm stunned by your level of detail! Maybe your wiper motor was built on 4/20 of that year, lol.

Last week after topping the system up with coolant, I discovered a small leak in the top radiator tank. I removed the radiator and dropped it off at a shop yesterday, hoping to get a repair to the tank. Visually, the radiator is in very good overall condition and it seems quite solid. However, from past experience with old radiators, I know there can be more issues than what can be seen. As it turns out, my fears were real. After doing some basic checks the shop has discovered there are many defects in both the top and bottom tanks... too much to repair. So Im now now in the process of getting a completely new radiator manufactured for this truck. I knew this old radiator was a bit of a gamble... At least I wont need to worry about cooling system issues for a few years.

I had that also when doing my M37 years a go I took a couple of rads in to get checked as they looked perfect just to find out the the tanks had multiple cracks in them and were not worth fixing them

Yes, that's it Dave. Mine had those small micro-cracks throughout both tanks. They said adding heat in the process of doing any repairs will make it all worse. I had a similar situation with multiple M38A1 radiator tanks in the past. The metal seems to get brittle with that much time and use (heating and cooling).

Radiators
I tried fixing used rads on my first restorations and always ended up having issues leaks and overheating.
We spend a fortune on the engine and skimp on the radiator to save on costs but in the end you’ll ruin your fresh engine rebuild. Good call. All 4 of my restorations have had rads redone, no engine issues whatsoever never had overheats even in the hottest weather.

Walde; I totally agree.

Never a restoration without a full radiator re-core. That’s always been my mantra.
My seemingly good Jeep rad unexpectedly decided to dump on my garage floor one day even before I got around to starting my restoration. Gave me incentive to get it done right
