Q: Radiator out and car not starting.

asked by on

My radiator went out and now my car won't start.

Hello, you say your radiator went out so i am assuming that the radiator was leaking and the car overheated at one point. Water was probably added to top up the system so the car is drivable. If I am correct there is a good chance that you have a blown head gasket and there is water inside one of the cylinders and hydrolocking the engine, or the gasket is causing a lack of compression letting the engine crank over and not start. To be sure that this is the cause for the no start you may need to get a mechanic to inspect your starting problem.
