Greg, I don't quite follow this... I understand the potential for additional load (less circumference to absorb the same load), but shouldn't there be less rotational speed with the smaller journal? With the less circumference, spinning the same engine RPM, wouldn't the rotational speed be lower? Doesn't really matter I suppose, but was just trying to get that in my head.

The fix?? Isolate the hell out of it... don't bolt it straight to the core support... Get some wubba (rubber) in there. Or have it supported in a way that the radiator "floats" on it's mounts.

The radiator in my car does 'float'. I think the 1st gens were mounted to the core support, but the second gens sit in 2 rubber bumpers at the bottom, and the cover panel holds it down from the top. So there should be plenty of ability to flex in my car. I really don't think that was the problem...
It's on it's way back to PRC now, should get there Tuesday, and I'll find out what the heck happened.
