I'd stick with a Behr radiator, not that there aren't others of equal value/performance.

I've followed a lot of radiator threads here and have yet to find any sort of solid consensus that anyone made anything near as good as Behr.

When mine gave up the ghost, I stuck with Behr. That was 4 or 5 yrs. ago.

You may hear yack here that Behr's upper necks are reinforced with a metal sleeve. They must of left mine out when they built it and I've heard from a couple of local independent techs that the metal sleeve insert hasn't been around in awhile.

Like everything else these days, corners are being cut to save $$$.

One of the things that kills the upper necks in my opinion other than age is overtightening. Back in the early days at this forum, a tech named Benzmac suggested that one use a cooling system pressure tester to adjust the upper neck hose. Refit everything, then hook up cooling system pressure tester. At this stage, your upper neck hose clamp is snug, but not too much. Pump the system up to around 17-20 lbs and gradually tighten the upper hose clamp until the leaking stops.
