Hey guys the machine was running a little hot so I took the radiator cap off and saw small black pieces of debris floating in radiator . I disconnected both hoses at water pump and flushed the system out . After reconnecting and filling again it was good for a few miles until I killed the engine and tried to restart it . It acted like it was locked up so I pulled the spark plug , cranked on it and blew water 3 ft high out of the spark plug hole .This may sound stupid but would me mixing up radiator hose connections at the water pump cause this .

 

Either that or if you didn't bleed the air out of the system when you flushed it, it may have over heated and blew the head gasket.If you need a good manual,here's a cheap one that can help.2006 Polaris Ranger 500 4X4 CARB Service Manual PDF Download
