>I also have been losing antifreeze for the last year. Not quite as >much as yours, more like 1 quart in three-four months. I cannot find any leaks, there is never any antifreeze on the garage floor, I never notice any odor and the oil is not contaminated. Its very mysterious, indeed. I've asked the dealer about this and they are clueless. An oil sample of used (at least 1000 miles) will let you know if there is coolant in the oil ($15-20). Since there is no "coolant fairy" slipping down in the middle of the night, sipping up the anti-freeze, it must be going somewhere. If it isn't internal, then it has to be external. A good shop will have a dye they can put in the coolant. Drive a while, then put the car on a rack and use a blacklight to find the source of the leak. Dick in Falls Church, VA
