This is a Caterpillar C15 diesel cylinder head that has several cracks from overheating. If a radiator isn’t maintained externally to keep it clean with no obstructions in airflow along with not maintaining the coolant which allows internal plugging and clogging of the tubes, overheating will result. Severe and excessive overheating will cause cracks in the cylinder head. So the moral of this story is to not neglect or cut corners with the radiator otherwise even more costly internal engine & cylinder head damage will occur.
