OK so i bought a 93 honda prelude SI with the H23..I bought it from a aquantence that is very ditsy and has never messed with a car before..she was told to put water in the ratiator and she puts it in the windshield wipers...So she is driving and the car overheats on the highway and now it wont start...What are all the things that could have gone wrong such as blown head gasket?...warped heads? anything else? and is there a good chance that im gonna have to rebuild the motor? Thanks For the help
