You'd be better off getting a new radiator with a warranty. No way could the end tanks be dropped off and replace the enormous Cadillac core for $40.00
No one knows what cadillac radiator you are talking about.
Get on the phone and call around your area to get an idea what you are facing.
Google the issue for drawings pictures, videos, what have you.
Parts ware houses, radiator specialists and wrecking yards can sometimes surprise you with availability.
SOME radiators can be re-cored, & that is usually cheaper then buying a whole new one. But $ 40 sounds too cheap.... Maybe double that number....
Sounds WAY too cheap for a re-core. $40 might get a crack in one of the tanks resoldered or a leak patched. But if you need a replacement core, it's going to cost hundreds.
Nobody can recore a radiator for $40. If it was copper, the shop just soldered the fin tube.
If your radiator is aluminum with plastic tanks, you need a new one. Nobody repairs the ones with plastic tanks.
40 bucks maybe 30 years ago, but I doubt you could get a proper job for that much anymore. But hey, maybe.
just buy a new radiator.
so the radiator in my Cadillac has a crack in it! and somebody told me that I told take it to a radiator shop and they could fix it cause he had his radiator break and they re cored his for 40 bucks! is it really cheap?
