I have upgraded my cooling system with a new aluminum radiator, water pump, fan clutch and shroud. Has gone from 230 plus at idle to a steady 210 with 180 degrees on the road.
I want to add a Spal Pusher fan. My question is which one ?
Do I go with the Spal 16 inch pushing 1920 CFM with 17.4 amps, or go with the
Spal 16 inch pushing 2360 CFM at 21.6 amps.
I have the original alternator in the 67 Chevelle SS. I do not have a stereo, AC, or power supplies. Will I have to upgrade the alternator.
Note: We conducted a test. With the 67 SS idling for 30 minutes it went up to
210 but stayed there. We used a floor fan pusing air through the radiator and it dropped to 185 degrees.
Comments please.
Thanks,
Ken McDee
