Description:Radiator group coolers are important components of the engine system, as they help to regulate the temperature of the fluids involved. The radiator is located at the front of the vehicle and is made up of a series of tubes and fins. The engine coolant flows through the tubes, while the fins increase the surface area of the radiator and help to dissipate the heat. hydraulic group oil cooler, on the other hand, is a type of heat exchanger that is used to cool hydraulic fluid. Attributes:• tubes and fins to increase the surface area for heat transfer.• Designed to handle higher pressures and temperatures.Applications:The Radiator & Hydraulic oil Cooler is used in cooling the Engine. It is mainly used in 426 F2, 424, 426, and 42 Backhoe Loaders.
