anyone here ever put in a "severe duty fan clutch" in their 10th gen F150's ?
I heard they usually go at the same time the water pump goes (vice versa).
Mostly age deteriorates them.
a "severe duty" fan clutch has more grab, thus more HP robbed.
more air moved per revolution with the "severe duty"

Motorcraft PW423 is what you need. F8AZ-8501-AA Ford part number. This fits your 2000 w 4.6 or 5.4.
In the cars, there are 2 different ones available. Something to do with the impellers. PW496 is the other number. Same housing and tubes, so that leaves the impeller either shielded or open fins.

(severe duty fan clutch with water pump assembly) but it's aftermarket made by GMB.

I can't find a "severe duty" fan clutch for the 4.6 made by motorcraft in a water pump assembly combo...
RA indicates Motorcraft fan clutches as "thermal" & ("heavy duty" YB3041)
should I go aftermarket, or will I regret it ?

I knew I should have put one on the side.

I'm needing the right side hinge insert. The dealer shows it in stock online. I went to get it with AKs part number but then the parts dude said the number wasn't right.
I was confused and thought I wrote the wrong thing. I didn't doubt AK, I doubted myself. Now I doubt the parts dude.
I'll drive up to Richmond tomorrow to see grand kids. I'll go by dealer there. They are pretty good.

I measured and it measures the same ID and OD as 1/2" Schedule 80 PVC
Thanks for pointing those out. May as well replace those while I'm doing the rest.
