Radiator tips for 67 Dart with 440

You have some other reason you can't keep your engine cool.

Debris in the cooling system.
Wrong water pump
Wrong pulleys
Wrong timming
Over thinking the water temp. (Raising a few degrees at a stoplight is normal. If it keeps rising then your have a problem)

The factory did not have cooling issues, 340, 383, 440 - 22 inch wide copper brass rads

I know 2 guys with 383s in their 67 and 68 darts. No cooling issues.

One has an aluminum rad, the other has a copper brass.

How is it possible that a fixed blade fan and no shroud can keep this one cool? BUT it does!:rolleyes:
