suzuki dt4 cooling problems

[johnmart]

having problems with my cooling system, my dt4 year approx 1990.

had an over heating and detected that very little water came out of the pee hole. eventually no water was coming through.

My impeller had gone. ive since changed the impeller oil seals etc,but no water is coming out ,after various tests we decided to pull the power head, the channels werent that bad but the jacket gasket had been overheated and has bulged. i think the engine has overheated. what do i need to change,the jacket gasket, head cylinder gasket ? also i found like a blob of solidified rubber inside one of the channels,cant figure out what part it can be.

thanks ,

The blob of rubber could be part of your old impeller, this is commen. If you have over heated I would recommend removing the cylinder head checking all water passages. I would also recommend checking compression.

Thanks we ll try that ,ive purchased the cylinder head gasket, the jacket gasket and a new cylinder head cover . this is the last thing i can do . hope it works!
