M43B16 radiator

[woerie938]

I want't to put A radiator from a e36 316i compact with M43B16 engine, in my e30 because the original is leak.

I couldn't find any info about this. Or is the m42 rad the same as a m43?

Will it cool enough with a M20B20?
Are there things i should know, or just fit it in and there you go?
