I have a 1993 ford taurus 3.8L V6 automatic GL. Everytime I drive it I can smell antifreeze. This happens year around. I had my radiator replaced about 1 1/2 years ago and my water pump replaced about one month ago so I know it is not coming from these two parts. I have checked all my hoses for leaks also. I even checked my antifreeze reservior for leaks and found none. I haven't checked my heater core because it is so hard to get too but I do not see any antifreeze leaking onto the floor boards. I check my antifreeze reservior level about twice a month and notice it is about 1/4 less than when I last checked it. What can be causing the antifreeze smell and the drop in the antifreeze reservior level each month?
