Whats leaking? (accy bracket/belt tensioner area)

I have an accumulation of droplets of a yellowish liquid on the underside of the accessory bracket in the belt tensioner area. I'm positive its not oil, so I'm assuming that it is either power steering fluid or coolant. It seems sort of oily, but not as oily as oil lol. I'm sure there are no leaks from the radiator, coolant hoses or the waterpump. I looked up at all the accessories, but I can't see where the leak would be coming from. Aren't the heater hoses routed down there somewhere I'm not sure? Any ideas on where I should look before I start tearing things apart?

Did you check the weep hole on the water pump?
If it's so small that your not adding fluid to anything you can probably let it go until it becomes obvious.

Nope, its a brand new battery, nothing leaking on it. I just installed an electric waterpump, new radiator, and new hoses, so I'm sure none of those are leaking. The weep hole is blocked off with a freeze plug and sealed with RTV.

I would examine the power steering pump and the hoses thoroughly for leaks. Also, look over the A/C components, sometimes if there is a leak in that system, it can leave an oily substance as well.

Yah, I'm thinking its one of those. I'm gonna get under the car today with a light and try and figure it out. I'm also thinking about wiping everything really clean, and then checking a few days later to see if I can find the source. The leak isn't too bad yet, and I haven't really noticed any of my fluid levels getting lower.

Sorry, didn't see the "electric water pump".
The oil that's in your A/C compressor is a light yellow.

thats a/c oil. power steering fluid is clear or brown. when a leak around the compressor happens it will leak oil. put some a/c dye into the refigerant and then check it to find the leak.
