hahahaha. i had the same problem 2 times in a year. guess how i solved it. i let it all drain out, drove slow to the dealer. parked the car in a wet spot, and traded it in!!!!! LOL

another thing to check for is the rubber gasket in the plastic overfill tank where you pour your antifreeze into. I flushed my system and put new antifreeze in and shortly after my low coolant light came on so I added more and it came on again and I added more and well you get the point. One day I finally saw the antifreeze pouring out and I popped my hood and noticed it was all coming out around my cap. I took the cap out and I must have damaged that rubber seal somehow because it was ripped in 2. I got a new one and I havent had problems since.

V-6 = Major problem with the LIM gasket, as Colin said.

4 Cyl = No LIM gasket, but the other *usual* GA problems:
* Cracked heater core plastic hose nipple.
* Cracked radiator plastic side tank.
* Faulty reservoir pressure cap, as dajuice stated
(Only tighten the new cap as much as an average woman can easily tighten one-handed.
Overtightening will cut or distort the rubber sealing washer.)
