This '73 Mustang has an engine problem. The customer complained of poor running and he kept having to add coolant and then, when he finally gave up, it had lots of white exhaust. So it sounds to me like either a bad head gasket or a broken cylinder block. We're going to tear into this car and find out exactly what. This car is fuel injected; it should start real easy. You just reach in the window and turn the key. Apparently, it is running badly. Right now, it doesn't sound so bad. Let's pour coolant in it and see what it does. Do you have coolant? I don't see any coolant in it at all. We're going to grab some coolant and put it in here. It has a reservoir on the side. It's empty, which indicates to me that it is sucking coolant out.
