I was driving my Honda prelude and all of a sudden it shut down and wouldn't start again. I pushed the vehicle to the side of the street and opened the hood. The radiator frame where the hose connected to was busted. No steam or overheating warnings came from the vehicle while driving. Is there more than just the radiator as it being the problem for reasons it won't start? Is the thermostat gone also and is that why there was no indication when driving that vehicle may have been overheating? It was very weird though that no smoke or steam was coming from the engine when it broke down. Could you offer some assistance.
What I got from the points you mentioned above is that there is something that hit the hose and maybe it also hit a wire (cam or crank shaft wire ?) which caused it to cut off the engine. If the car did not overheat, even when there is no coolant inside the radiator, the car should still start.
