Overheating problem
Car overheated, wouldnt cool down after adding water and turning heater on. Stalled, then wouldn't start. Had it towed home, didnt mess with it at all. Tried to start three weeks later(it started). Turned off immediately. Today I checked oil to see if milky or if water in it(no bubbles or water in oil). I cant afford to take to shop. What do I do from here to see what will get it safely back on road even if for temporary? Havent tried to drive it at all. Only started it that one time. Desperately need to have running car for short trips.
