I'm trying to keep the engine at its coolest so I don't get 0133 head problems. I'm waiting for Champion radiators to get some three core radiators in stock to make 100% sure it doesn't have a problem. I would be sick if I hurt this 4.0 since it runs so nice.
Check the harness side of the fan connector for 12v- it should have power when the compressor is running. If it does, and your fan isn't coming on, replace the fan. If it doesn't, check the fuse and the fan relay.
