Anyone know the difference between these two fan clutches, other than
the obvious specs listed below off the rock auto web site.
I have a 92 K 1500 350 engine, 7004R trans with 4.11 gears and
I've had the 15452 clutch for some time on my truck. I made some
modifications including going to larger tires, and lower gears as
listed above. I bought a 154495 clutch and swapped it out. The truck
does run cooler but I'm not sure the clutch is working right because I
never hear the "roaring" noise you hear when the fan clutch engages,
no matter how hard I run the truck or how hot it gets (around here
lately its been in the 90's, in AL) I'm wondering if this fan clutch
is not staying engaged all the time, or partially engaged. IF it were
I should hear the clutch kick on or the fan noise would be apparent
all the time.

IF you look on ROCK auto it will list a number of descriptions for the
GM fan clutches for this year truck, but if you look at the part
numbers they are only talking about these two below.
The truck came stock with 3.42 gears so that's why I had the 154552
clutch. I was just trying out the "95" clutch to see if the truck
would run a little cooler and indeed it does, but I never hear the
loud roaring noise that the fan clutches make when the fan engages?
