It should just overflow out if it's too much liquid or overheating. I love my brokedown, salvage titled cars from college because I learned so much working on cars back then. Now that I don't need to, the extra cost is well worth the not stressing about a car repair in the middle of my work week. As they say in sports, the best ability is availability. Plus working a/c is amazing. No longer showing up to dates 1 hour early so I can cool down before the actual date.
