WARNING CAUTION (1) Pressurize radiator overflow tank, using tester, to 15 psi (103 kPa). (2) Observe radiator overflow tank for coolant leaks. NOTE Do not pressurize over 16 psi (110 kPa). Failure to comply may result in damage to cooling system. 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. Pressure loss without external leaks indicates engine internal coolant leaks. Change 2 2-133 (3) Observe radiator tester for loss of pressure. (4) If cooling system does not maintain pressure, go to step 7 of this fault. (5) Remove tester and test kit from radiator overflow tank. (6) Install radiator cap on radiator overflow tank.
