I've seen some threads on changing the oil but how do you adjust those points? I assume it's something you change while the hub is disassembled?I had to re-oil and re-tune an aqua hub fan clutch to get it to keep enough friction to turn the fan at highway speeds. Of course, verify your radiator is flowing enough- as you said you have. If you have flow, you have a sealed system, then it's either an excess of heat generation (mechanical badness) or a lac of air flow over the radiator. Another factor could be an thing inhibiting airflow, such as buggs clogging the ac/ condenser. After I took care of all the usual suspects, my issue was the stock tuned fan clutch just didn't have the balls to function in a high heat environment. The opening and fully locked-on temperature for the fan clutch can be adjusted to open and lock-on sooner, and thicker csk oil can be added to prevent sheering and slippage. HTH
