Default '93 Camry V6 overheating

I had the same problem. The radiator got cleaned and refilled and it
seemed that the problem was solved. Does anyone knows how the
hydraulic fan is controlled ? Can I change the hydraulic fluid and is
it necessary ?.

Ahem... Jason .... the system used on Camry is a pair of hydraulic
turbines driven by pressurized fluid from the power steering pump.
