i just bought an 2000 impala from private owner, i drove it for about 20 mins then it started over heating. i looked on dash it said low coolant level i looked into the hood oil was ok not milky. but i checked coolant reservoir. it had water in it and the tank had rusty looking substance on the sides of it and the radiator cap had rust on it. there was also a white powder like substance of some parts of the engine.fan was blowing. radiator looked pretty good. i was told it should be flushed. i also noticed water in coolant tank was high but after about 15 mins the water level had dropped(car was off)im fearing that it may have a blown head gasket. i have not seen and white smoke come out exhaust pipe but still not sure im very stressed out i saved for a long time and now i buy a peace of junk thats over heating

 

If you dont put some actual coolant in there you will blown a head gasket. Cant beleive you didnt look at this before you bought it.

 

ya stupid mistake. wasn thinking i should have known she had told me she just put coolant in it so i didnt bother to look i kinda feel the head may already be blown. i will have to drive it again to get it to a michanic

 

Why cant you have it towed?
