I have Haynes manuals for a 2001 Sienna and 2000 Camry. Both of the vehicles use essentially the same V-6 as the RX300. The Haynes manual suggests changing both belts at the same time. It states that the PS belt can be changed by loosening the adjustment bolt that secures the pump to the slotted bracket and pivoting the pump (away from the engine to tighten the belt, towards the engine to loosen it). Repeat the prodcedure until the drivebelt tension is correct and tighten the bolt.
