This is the information on the GM 11 blade conversion for the Jeep Liberty diesel.
Have no idea if it will work on Gas models. Looking at the pictures of the fan clutch on the Mopar sites, it looks like it uses the same mounting threads as the CRD fan clutches. If that is the case, the 11 blade fan and fan clutch should work on your 04 Liberty?
It turns out, the Chevy/GMC trucks years 1996 through 2007 HD fan and fan clutch with factory installed towing package are a direct replacement for our Jeep Liberty CRD and the prices for the GM parts are a lot less expensive than having to buy genuine Mopar parts to get the HD Liberty Gas burner cooling fan and clutch that some on LOST have suggested to use…
