3 Radiator Choices, Which one do I use?

[Tico Frank]

I will be swapping my m50 in the next few days and I have 3 radiator choices.

#1 E36 M3 Radiator

#2 E36 M42 Radiator with the reservoir on the side.

#3 Stock E30 M20 Radiator

I would like to use the E36 M3 Radiator but I have never seen a pic of one and need to know if it would use the stock m20 reservoir?

If you have a preference please explain why, thanks

I would like to sell the other two as I don't think I need 2 extra rads.

stock E36 and late M20 rad are basically the same.

I'd go M42 rad. It's been great for many people in combo with a SPAL (or similar 16" electric fan). It's a cleaner engine bay too.

Unless you're doing a lot of hot summer traffic idling, you won't have any issues with it.

e36 all rads are the same as m20 88+ rads, M3 or not no difference the only e36/7 that has a different one is the Z3M, but the m20/e36 rad is fine, the 24v motor really doesnt require any extra cooling that is able to fit under the hood of the e30 chassis

The m42 radiator can be a bitch to bleed but cleans up the engine bay nice. E36 radiator and late model m20 are practically the same.

I choose the m42 as well. Works great looks even better
