RADIATOR REPAIR - CONTINUED
Particles blown by compressed air are hazardous. DO NOT exceed 15 psi (103 kPa) nozzle pressure when
drying parts with compressed air. Use a maximum of 30 psi (207 kPa) when cleaning components. DO NOT
direct compressed air against human skin. Failure to follow this warning may cause injury or death. Make
sure air stream is directed away from user and other personnel in the area. To prevent injury, user must wear
protective goggles or face shield.
Do not attempt to clean radiator core fins with any sharp instrument. A sharp instrument may damage core,
leading to leakage from core.
Remove dirt and other debris from core fins using compressed air.
Remove any surface corrosion from upper and lower tanks using a wire brush or sandpaper.
Inspect core and upper and lower tanks for small holes, or for other evidence of minor leaks. Repair minor leaks by sol-
dering or brazing.
Check filler cap opening pressure in a suitable tester. Opening pressure must be a minimum of 7 psi (48 kPa).
Check drain petcock (4) for damaged threads or signs of leakage.
Install drain petcock (4).
Assemble shroud (2) to radiator (3) and secure with
eight screws (1).
Install radiator (WP 0053 00).
Operate engine, check for proper operation and leaks (TM 10-3930-660-10).
