belt squeal with SD fan clutch
fought thos as well with the SD clutch. hey its pulled air at idle awesome but did get
belt squeal at certain RPM. HD clutch worked well with no squeal. Also make sure PS
belt is wider to properly seat in pulleys. Also I choose the standard duty clutch as once
I installed a cold case radiator that really dropped temps. with standard clutch my highway
temps are perfect and better gas mileage. just have 10 degree temp creep at extended idle
when I am in traffic, drops to just above stat once rolling again.
using 7 blade AC fan from 76 TA with AC and AT.
