1. After draining the waste oil inside the radiator, remove the oil cooler. After flattening the removed cooler, fill the inside of the cooler with water through the outlet of the oil cooler. During the experiment, block the water inlet and use a high-pressure air cylinder to inject air into the cooler on the other side. If water is found at the oil inlet and outlet of the oil radiator, it indicates that the internal core or edge cover sealing ring of the cooler is damaged.
2. Remove the front and rear covers of the oil radiator and take out the core. If the outer layer of the core is found to be damaged, copper welding can be used to repair it. If the inner layer of the core is found to be damaged, it is generally necessary to replace it with a new core or block both ends of the same core. When cracks or fractures appear on the edge cover, cast iron welding rods can be used for welding before use. If the sealing gasket is damaged or aged, it should be replaced. When the copper pipe of the air-cooled oil radiator experiences detachment, it is generally repaired with copper welding
