Magnum in 70 Dart, can't keep it cool.

A electric fan with shroud should help as mentioned. A step further would be a mechanical fan with clutch and shroud. My Dodge ram has a 5.9 and it has a mechanical fan with shroud w/195 degree thermo. I had over heating problems in my cuda so I upgraded to a Griffin rad and a mechanical fan with shroud. This cured my problem. I just never had any luck with a e-fan . The fan I used moved 3650 cfm and still wasn't enough.

If you don't have a big trans cooler I highly recommend that as well.
