I found a crack in my radiator end tank today, so I'm going to replace the radiator. Couple questions:

-Mine is an automatic, do I have to worry about spilling ATF? I know there's a cooler built into the radiator somehow.

-Is the 328i radiator the same as the 335i? There's a CSF aluminum one for 335i/auto but none for 328i/auto.

Any other thoughts (and prayers) are appreciated.

In situations like this you can go to realoem.com and compare part numbers for the 335 and 328 radiators and see if they are the same.

I have a manual so can’t help you with the tranny cooler question. Good luck!

Gotcha yeah they're definitely different, I guess what I was wondering was if the 335i one would fit and if so, would it be an upgrade.

I think I'm probably just going to go OEM behr though. Or just JB weld the crack

The ATF cooler is just bolted on with a torx. You'll have to take it off to remove the fan. You will not lose any ATF fluid.

Gotcha. Yeah I took a good look at it last night. Its got a hose running to the cooler, but its got coolant running through the hose, not ATF.

I ordered the parts this morning, hopefully its not too awful to do.
