Y'know, it's very funny, but in the couple decades I've had vehicles
with plastic-tank radiators, I've had exactly *one* failure, and that
('98 BMW 540i) was of a vent nipple on the top of the tank that broke
off in its fitting (that part is $7, though for other reasons I replaced
the radiator.)
I've never, ever had a tank leak at the tank-to-core seal. Maybe I'm
just lucky (at that, if little else...)
I've had soldered-metal radiators fail, though.
John.
