2004 Denali severe duty fan clutch

[schimme]

I'm in need to replace my fan clutch and also need the most cooling possible for my use case (Severe use in the Andes, long 1st gear climbs in high altitude).

Can somebody help me with part numbers for severe duty clutches? Any make is ok.

thanks folks!

This is for a LQ4 / LQ4 LS engine, or an 8.1 Big Block?

2004 - either LQ4 or LQ9 - I have an LQ4 - try the newspaper trick - see if a rolled up newspaper will stop the fan at idle. I had a bad original fan, and I got another original fan. All my issues went away. Andes, and first gear, that is harder, and how do you get parts?

This is Toyota, but I've been thinking of this, both for the old Yukon fan, and for the BMW

Blue fan clutch mod...Thread has gone to hell, read at your own risk

History: On my first drive this summer after replacing my transmission I was having an overheat condition with the truck. On the following weekend while towing a camper it was real severe in the 230* range. After returning I was able to confirm that my Blue hubbed fan clutch was to blame...

Go to www.gmpartsgiant.com and enter your vehicle info or VIN), and look there under the cooling system category. Don't buy there -- use that site just to get info and part numbers.
