2001 dodge neon 143,000 miles I think it's 1.6 liter automatic. It started to overheat the other day so I stopped engine, let it cool. Coolant was empty so I added. Ran fine for one day, then coolant empty again although no sign of major leakage. Used stop leak ran fine for 2 days. On my way home from work odd tapping noises (like something hitting fan) and a few sounds of screeching belt. The sounds suddenly stop and my car stops accelerating and engine turns off. (Was not overheating at this point), the coolant was empty again, will not turn over now and now when you add coolant it sounds as though you are just pouring it on the ground but yet since it's so compact we cannot see where it is exactly leaking from. Where is the water pump located so we can look at all of that? Do you have an idea of what it could be and do you think it's done for?
