If factory OE/replacement has plastic on end tanks then this is where the crack/leak in the future.

Looks like the aftermarket radiator has all alum on core/end tanks.

Thanks for the link and confirmation that 745/545i has the same part # and link to all aluminum radiator. Saving the link to my "545i issues folder"

Yes on my 545i the factory is aluminum with aluminum tanks.

If you go with after market be aware you may have some fitment problems, as there are covers, and brackets, that are bolted or screwed to the the tanks.


You are working on a car that was once worth over 50K. This is not a 69 Camaro where tolerances were large. For me fitment and factory performance is most important.




For me looking at the pricing in the links here, the savings is not worth going aftermarket stick with the factory style BEHR units.

yes, factory is all aluminum (BEHR)

Aaah.. I see. if that's the case then of course I stick w/ OEM/OEM grade replacement.
I thought factory had some plastic on the end tanks which of course I try to avoid during replacement
