WARNING Coolant may be very hot and under pressure from engine operation. Ensure engine is cool before performing troubleshooting. Failure to comply may result in injury to personnel. CAUTION Do not pressurize over 16 psi (110 kPa). Failure to comply may result in damage to cooling system. (1) Pressurize radiator overflow tank, using tester, to 15 psi (103 kPa). (2) Observe hoses for coolant leaks. NOTE Pressure loss without external leaks indicates engine internal coolant leaks. (3) Observe radiator tester for loss of pressure. (4) If no external leaks are present, perform Cooling System Troubleshooting (d2. Oil in Cooling System). (5) If external leaks are present, replace upper coolant hose (para 6-10), radiator overflow tank hose(s), or radiator overflow tank (para 6-3). (6) Remove tester and test kit from radiator overflow tank. (7) Install radiator cap on radiator overflow tank. Change 1 2-141 TM 9-2320-365-20-1
