spectra premium heater core issue ? / anyone recommend a good heater core ?

Well all I was trying to say is that 1) Spectre is made in Canada. That's a fact. 2) ALL the parts they make are not bad.

Everybody here knows how mass production works. It's the same whether it's here, or any other country. As many parts as are made, there are BOUND to be some bad ones.

Sorry for the trouble I obviously caused.
