My husband recently left to fight this great war and my car is acting up. I put coolant in the dex cool container on friday afternoon and here it is sunday and all the damn coolant has leaked out. what is the problem and is it major? this is my only means of transportation to work and for my kids to get back and forth to school everyday. please give me an idea of what to tell the mechanic. i want to have some type of clue so i wouldn't get take advantage of.
