What is the current recommendations for a heavy duty fan clutch? I have been using the AC Delco 15-4644 but that is no longer being made.

Emery,

For what it's worth, I went through 2 Haydens that did not cool correctly out of the box, and decided to try something different.

Went with the Severe Duty GMB 930-2010 and it's cooled my coach great this summer here in Texas....

Only had it on a few months, but just the fact that it actually worked out of the box makes it better than the Haydens so far...

Cool is the important part but costing is the whole reason to have a
clutch in the first place. How well did the 930-2010 cost?
My fan seems to run all the time.

Jeff Sirum put a Hayden severe duty clutch on my 455 about 6 months ago and so far it seems to be functioning as it should.
At low speed here in FL it engages but once out on the highway at speed it disengages.

It works correctly, John. It would come on if temps started to go up (207-210 on my gauge)and cycle off when down to 195 or so. Ran a lot if it was over 100 ambient, only on hills if in the 90s, and hardly at all below that.

I believe the severe duty does run a slightly higher fan rpm when not engaged, which is what I wanted. They offer a standard and HD as well, same as Hayden and Delco.
