If someone can tell me why my nissan altima only makes a whirling sound and not start after I ran it hot I would be much obliged. I cant afford to have it towed to a mechanic to look at it so obviously i cant afford repairs right now but I'm hoping what ive researched on the internet isnt all true. I hope I just blew a head gasket and it can easily be replaced and not have warped the engine block itself. It wasnt showing hot it just felt funny although the car had ran hot a couple times before because the hose kept coming off. I thought it was just loose so I put a clamp on it thinking that it would be good. It mustve been building pressure for some reason because it popped off again but I paid no attention because i waa sure it was fine but I was driving on the highway and felt the start sputtering and said oh no and my wife said what and i said the car feels funny. She said get off on this exit so I pull off and right as i got off the car died and had enough momentum to pull into a lot. After that the car would not start. Its just making a weird sound. Had to get it towed home. Please tell me I dont need a whole new engine.
