Cooling suggestions (fan)

I learned through trial and error (mostly error) and came up with what works well for me. A 16lb radiator cap to start (pressure equals a higher boiling point) a 195 thermostat (proper cooling is about heat transfer) and a 50/50 mix of good antifreeze (no more/no less) along with a good clutch type fan with a shroud. My cars run cool enough to idle through town on a 90 degree day without overheating.
