2-6. SERVICE BEFORE OPERATION (CONT).

Do not remove the radiator cap when the engine is hot; steam and hot coolant can escape

and burn personnel.

Use extreme care when removing the radiator pressure cap. Sudden release of pressure

can cause a steam flash which could seriously injure personnel. Slowly loosen cap to the

first stop to relieve pressure before removing cap completely. After opening, securely

tighten cap.

Use a clean, thick waste cloth or like material to remove radiator pressure cap. Avoid

using gloves. If hot water soaks through gloves, personnel could be burned.

(7)

Check radiator coolant. Check if solution is adequate for expected climatic conditions. Refer to

TB 750-651 for preparation of antifreeze solutions. Put tag near filler cap with type of antifreeze and

degree of protection written on tag.
