Figure 6-4. Radiator Core, Puncture Repair.
(h) If epoxy or solder is available, seal the coolant tube ends.
(i) If no epoxy or solder is available, fold the tube once more 1/2-inch to restrict the coolant leaks.
(i) Reinstall the coolant. Inspect radiator for leaks.
(k) Install radiator cap in pressure release position.
Record the BDAR action taken. When the mission is completed, as soon as practicable, repair the generator using
standard maintenance procedures.
6-13. Hose Clamp, Broken. A broken hose clamp will allow the hose to leak coolant and--cause engine overheating.
The clamp must be replaced or a substitute improvised to regain a sealed cooling system. If a replacement clamp is not
available wire can be used as a substitute. Care must be taken that the wire does not loosen.
