Best cooling fan for best cooling?

Yes I already discovered them both from other post. I have the new distributor shaft and bushings with the pre drilled shaft and screw. Thanks for the warning.

The two blade fan, with the fake water pump studs, allows you to pull the pump without moving the radiator. Don’t forget the cardboard to protect the radiator, though!

If yet to make a Flush/Backflush tool, here is my home made tool. Rubber Automotive Freeze Plug available from auto parts store. Drilled through the freeze plug undersized hole for garden hose fitting, and a cheap garden hose on/off valve. A little electrical tape to help the adapter fit the coolant hose a little better. Use existing hose clamps. Can be a little fussy to keep it in position/sealed. Use the on off valve to cycle full house water pressure every few seconds. I drain into a large 20 gallon tub positioned under the outlet to inspect results . Do not forget to remove upper hose filter screen while flushing/backflushing. There are other ways to do this, but they required tools etc. I do not have, and this is cheap. Two are needed, one for upper hose diameter, one for lower hose diameter.
