2nd radiator replacement

At 4 years and 30k miles we replaced our first defective radiator. At the time our extended warranty co. required us to install an OEM radiator, supposedly an improved version of the original, from Radiator Specialists of Sacramento. I was willing at the time to pay the difference for a new radiator from Mac's but the Warranty Co. wouldn't budge.
Now at 10 years and 70k the replacement has begun to seep. This time the bill is all on me. I really wouldn't recommend using any of the "new and improved" radiators that are still available out there from when the factory closed.
I will probably contact Mac's in Portland for this repair unless anyone on this forum has a suggested shop somewhere the SF Bay Area. Would appreciate any recommendations.

Good company in sweet home Oregon called Radiator Supply House. They manufacture the good 3 piece copper core radiator at a decent price.

As I understood the original issue, the OEM radiators were produced using an epoxy-based seal for all the seams--cant be repaired once they fail. Thought the "new/improved" radiators used the traditional weld/solder process--thus they can be repaired. Also at issue were potential problems with vibration--were the fastening points modified to dampen vibration on the second radiator?

Old Scout- the dampening points were modified as required. Obviously didn't help much.

Jerry, Mine went out just after yours last time. It must be contagious... I just had to replace mine again last month. I got one from Burk Morgan (509-961-0996). He can give you better details on improvements on ones he has. Also, Mission Sales was out of mounting grommets but referred me to Radiator Supply House (887-651-3002), who really seemed to have their act together. They knew Alpines and the mounting grommets they sent seemed to be a real improvement over what we were using last time. A word of caution: check the mounting screws on the CAC when the radiator is replaced. more than half of mine were missing or broken. The good news is that the CAC itself is fine. We will be in Newport for a few days, if in the neighborhood PM or call me.
