390 Overheat Problem Fixed
Hypoid, Bear 45/70, Seetwisted, NumberDummy,
Thanks for your input on my overheat problem. You had good advice or made me think about what I was doing. This morning I let my car ( 1957 Fairlane ) idle for 30 minutes and it stayed at 180-185 degees without any movement on the guage.
1. I already had installed a four row radiator.
2. I removed the fan shroud. ( fan was sitting too far inside shroud to do any good)
3. I installed a 180 degree thermostat. ( was 160 degree )
4. I moved fan to within 3/4 inch of the radiator. ( was 1 1/2 inches )
5. I removed noisey six blade extra cooling fan and installed a stock 1957 four blade fan. ( tips are suppose to be bent toward radiator )
6. I replaced the 7 inch water pump pulley with a 6 inch. ( gives it 15% more fan rpm at idle )
Thanks again.
Jim

Thanks for the follow up Jim.
Let me guess, it's to keep the fan out of the radiator when the Rs go up?
It's nice to have all that in one spot. Hopefully your blood, sweat, and tears will spare someone else the trouble.
