Fluid drain hole??

[haljay007]

2007 Avalon. About 59 inches back from the front bumper, there
is an apparent fluid drain hole - a little rubber thingy about
an inch long with about a quarter inch opening. I notice some
fluid(maybe a teaspoon) in my garage after parking overnight.
It does not seem to be oil or transmission fluid but sort of
slippery water. It is quite a ways back from the oil pan.
It is not where the A/C water usually drips.

Someone know what the drain hole is for? Thanks.

Is the slippery water a pinkish color? That would be the color of your coolant and coolant has a slippery feel when you rub it between your thumb & index finger. After not too long, the slippery feel dries up.

I would place a clear glass or clear plastic container at the spot where it collects and note the color of the liquid. If it's clear, I'd say it's your a/c evaporator drain.

Another remote possiblity is the windshield washer fluid, but that container is more fwd. of the location you describe.
