GOOD LUCK! YOU HAVE TO BE ABLE TO FIND THAT MUCH OF A LEAK! HOW LONG HAS THIS BEEN GOING ON?
1 TO 5 "GALLON" PER "DAY"??? I WOULD LIKE TO KNOW WHAT YOU FIND OUT. WITHOUT BEING ABLE TO LOOK FOR MYSELF NOT A CLUE.
Are you having to keep refilling it , or is it just a puddle under the car ? ...What's the weather like , high humidity and A/C running constantly? Are you filling it with water or anti-freeze? Is soy milk really a good alternative?
