Official Jeep Grand fill please

Turbo on Tue July 28, 2009 6:11 PM User is offline

Year: 1999
Make: Jeep
Model: Grand Cherokee
Engine Size: 4.7
Refrigerant Type: 134a
Country of Origin: United States

Can someone here please give me the correct factory fill for a 1999 Jeep grand cherokee 4.7. Here is my problem. Under the hood is the factory sticker or 24oz. The official jeep service manual from chrysler/jeep says 26oz. The Napa listing on this site says 98-99 26oz. but the 98 jeep is a different body style? Now this gets even stranger the 2000 jeep manual and napa say 24 oz but the 1999 and 2000 are the same jeep? Now, I also have seen a 2004 which is the same body style but with a better ac system so they went up to 27 oz for the 02-04. What is going on here. Anyone have a better source for my fill thank you.

Thank you. I was leaning toward that but the sticker under the hood had me confused. One last question. Would upgrading a mechanical factory fan to a very large electrical be a reason to add more than a factory fill? I would think the system would be more efficient so a little more charge such as an oz or two could be used for better cooling? Would I be correct in my thinking?
