Fan and Clutch - D1

[Brockflock]

I read somewhere that there is a x-ref for the D1 cooling fan and clutch to a GM part, but can't find it. Anyone know if this is true, and if so what or where?

Thanks.

Search using Viscous and you'll find what you are looking for. Easy job so no worries!

Here you go.

Original Post by p m, sometime in the past.

Kragen etc.: Hayden 2786 (heavy-duty), Ready-Aire 4858R (heavy-duty), Imperial 215158 (severe-duty)
NAPA: TEM 271312 (severe-duty)
AutoZone: TorqFlo 922744 (heavy-duty), 922786 (severe-duty)

All - reverse rotation (serpentine belt!).

All list them for mid-to-late 90s Chevy 4.3l V6-powered trucks.
I'm going to try one tonight.

in a nut shell

the heavy duty will be a little better then stock...once you close the hood you wont really know the difference.

the severe duty will rob about 1 MPG but will cool better under hea vy wheeling or towing...get ready for the sound of a jet engine but it sure does a great job

hey all, i need to change my fan clutch as well, can anyone confirm that these part numbers will fit the '99 D1 GEMS engine?

Thanks!

Your driveway will never need to be swept up if you put the severe duty clutch in. Just about have to keep the brakes on to prevent it from flying away.

I did the Imperial dont think it was heavy duty one 215157. Been on there over a year and no problems.
