320i Plastic Aluminum Radiator

Here is some basic radiator info from the late Curt Ingraham who built very nice 3-core units for our cars before his passing:

The early (77-78) 320i radiator is copper and brass and of similar construction to the 2002 radiator. The hose fittings are exactly the same as for a 2002 radiator. You can use the 320i shroud in your 2002 if you locate the radiator mounting points carefully.

The late (79-83) 320i radiator is plastic and aluminum and about the same size as the earlier all metal radiator. I don't know if the lower hose fitting is the same.

The core on the 320i radiators is about two inches wider than a 2002 core.

The E30 318i radiator is plastic and aluminum and about the same size as a 2002 radiator. The hose fittings and mounting points are different.

For the three options above you need to adapt the mounting points and hoses to the 2002 except as noted. In that sense, none fits "perfectly" in a 2002.

Copper/brass radiators cost more, last longer, repair easier, and weigh more. Plastic/aluminum radiators are cheaper and lighter.
