    I am a newb here. After 40 years of dreaming, I am finally a vintage Mustang owner. I recently purchased a nearly all-stock 66 coupe 289 2bbl C4. On one of our 1st outings with her, we were stuck in a VERY long line to get into a drive-in theater and I realized the temp gauge was moving up...

    My engine was idling for about 20 minutes before my radiator exploded! Any ideas why? The radiator was original as far as I know. It burst at the seam of the top of the radiator. Is there an underlying issue I can test for and address, or should I just buy a new radiator? I don't want to blow...
