Hopefully someone will have seen this before...

OK. 1997 Taurus 65k.

Whenever I take a very sharp corner (usually a right turn) or slow down from
a high speed I hear a 1 or 2 second long high pitched squeelling (almost the
sound of whistle/air vaccuum sound - not metal on metail sound) coming from
under the hood in the direction of the passanger front wheel.

A second or two later I can smell what I think is coolent/anitifreeze coming
from the air vents. It all goes away until the next hard corner / brake I
make (usually 2 times on a 10 mile journey).

I initially thought it was windshield washer I was smelling, but then I
noticed that I have to keep adding coolent to the resevoir ever 3 days or
so. Not much, perhaps a couple of cups worth, but I have to do it regularly
as it does go down. I've checked for coolent leaks under the car and along
the hoses and clamps with the radiator but can't see where it might be
coming out. I even put paper under it to see if it drips but I can't find
any drips. Does coolent smell anything like windshield washer fluid (that
windex type smell)?

Oh yeah, the engine temperature has never read anything other than normal.
It has never overheated.

Can anyone suggest what is happening? I'm happy to keep driving it and
filling up the coolent ever couple days as I really don't want to spend any
money on the car, but my wife thinks we are going to gas ourselves and end
up with cancer from the occasional fumes unless I get it fixed.

Has anyone ever seen this before?

Thanks for the advice.
