Why is my Jeep still overheating?

Overheating when under load does not sound like cooling fan issues - as if you are getting ample air flow, the fan doesn't figure in. If you have an air pocket in the cooling system still following repairs, you can get some overheating. If you are dealing with a water pump that isn't circulating coolant, that can be a possible (but unlikely) cause. I'd check for air first, and the correct thermostat.
