The Dealer Service Tool has released the 259-6237 Coolant Tester Gp for pressure checking the cooling systems on the above backhoe loaders. Further, the tester group will work on several light commercial vehicles, passenger vehicles, marine applications, and motor cycles with internal diameters of 45 mm (1.77 inch) or less on the cooling systems. The cooling system tester group includes the following components:

• Extensions

• Gauge

• Supply hose

• Drain hose

• Instruction manual

• Carrying case

To use the tool, the technician attaches the tester group to the radiator. Then, the technician inflates the bladder. Next, the technician pressurizes the system with the pump. The gauge in the tester group will indicate a pressure loss if leakage occurs.
