First make sure the cooling fan fins have not worn down, second make sure that the engine is blown out at least once a day during the work season(this means removing the side shield and cleaning too),third make sure there are no oil or fuel leaks(oil or diesel leaks mix with chaff and plug the cooling system),that covers the engine. Now make sure the accelerator rolls are good(can't see light between them) The rest is fairly common to all combine adjustment and maintenance.
