Being as high as it is, its probably power steering fluid. Pull off the engine cove that you wrote the timing belt info on and see if there is anything on the back of it. If its on the back a lot, It probably isn't from the power steering pump.
Yeah best case scenario it's the O-ring right there at the pump, but I'm guessing it's the hose itself. All one piece into the abyss. And that's definitely a v6, pump's mounted on the right on the 4cyl.
