I am trying to locate the service manual / parts lists for our engine so that I can get some maintenance done and hopefully correct an overheating problem. The previous owner told me that it was an Isuzu 45hp diesel and the numbers on the block say G221 sounded easy, but I have not been able to find anything on this engine online. Anyone know anything about these or a better way of identifying the engine or locating parts for it? Any help would be appreciated.
Thanks

Here I was looking for G221...Thanks a bunch... I have to replace the head gasket. I am losing a little coolant and start to overheat over 2000 rpms. After a day of running at 2k I will have to put in almost a quart of coolant. I want to replace the head gasket and shave the head true to be on the safe side.
