Advice about fan clutch

[eran tomer]

Hello
I got from the local dealer these part numbers according to the vin. He can’t tell the difference between them. My car is 95 suburban k2500 8600gw with a/c and 4.10 rear axle. Does it take a standard duty or heavy duty clutch? And what are the 2 letters codes?
Thanks

Depends on your application. Here's a good explanation of the difference between fan clutches though

The two letter codes are what we call Broadcast codes, it is essentially a stamping number. Your original if it is still in the truck will have a sticker or a stamp with a 2 letter code on it. Since your climate is dry and hot i'd go with the heavy duty clutch fan regardless what the code is. The mounting should be exactly the same.

8-lug truck or 6-lug?

With those stats, I would just go with the HD anyway

If its an 8600 GVW, k2500, with 4.10 gears, I'd suspect the only option is 8 lug wheels.

I've never seen a light duty 6-lug 2500 Suburban anyway...
Has anyone?

 

[eran tomer]

Yes it’s 8 lug.

No, I don't think those were ever made... (2500 light duty 6 lug suburban)

I've only ever seen 3 character broadcast codes. I didn't know some were only 2.

Yep We(GM) use anywhere from 2-4 character codes that I have seen anyway.
