Engine parts that have water inside
 

What parts of the engine have water inside?

On Saturday, I noticed water dripping to form a small puddle under the engine compartment of my 2005 Honda Pilot. I had just done some highway driving with the AC on. It's possible that it isn't water, but it was clear and non-oily. The dripping eventually stopped. No warning lights or problems with temperatures.

Any ideas guys?

Thanks.

condensation from the a/c. drips out of the drain hole tube from the evaporator box. its normal

As stated, normal.

If it was coolant and smelled sweet, that's another story.

Ok thanks for the replies guys - just wanted to make sure it's not the sign of a bigger problem. Moderators, close thread if/when possible.
