Hello Bswwood, Thank you for that info. The unfortunate story that was told to me about this machine was that an operator for the guy who owns the machine, put straight water into it with no Antifreeze. Not sure what happen after that, maybe froze up at some point in the winter? I was told the head gasket was changed out and the machine has never run right since so it has just sat for the last two years. Now I get to dig into it to see whats wrong? It's my understanding it's putting pressure into the radiator, I have not looked at the machine to know if this is true or not ? Until I dig into it, for all I know it could possibly have a cracked and or wrapped cylinder head? The owner had a young inexperienced mechanic do the work so it's hard to say whats all wrong? They also had no shop service manual as a guide either. I am just trying to do my homework before I open up this can of worms! LOL Might you know if the Daewoo / Doosan DC24 engine that is used in the Doosan forklifts, is the same parts and gaskets as the Doosan D24 engine? I have yet to contact the Doosan forklift people to confirm this. Thanks again Mike
