Install of Old Air AC system and not that cold.

[Kw69]

Hey guys,

Well I finally got the new Old Air Hurricaine system installed and charged today. Proper Ac charge and no leaks, but was only blowing about 60 degrees out the vents. The fan is a factory 5 blade with clutch and the truck had original AC prior. Do I need to update the fan and clutch to a plastic unit? I'm using the original 5 blade all metal fan, and for all I know this could be the original clutch as well. I see the fan turning, but don't really feel any air pulling through the condenser. I did read about needing a 6 blade fan according to the instructions. So I'm thinking the fan or clutch is the culprit. If so what should I get? Should I go 6 blade plastic? Anybody run into this problem before? Thanks in advance! BTW I don't want a flex electric pusher fan if possible.
