DRAIN AND FILL COOLING SYSTEM - CONTINUED
DRAINING - CONTINUED
Open draincock (3) on lower radiator pipe (4). Allow antifreeze to drain.
Remove plug (5) from thermostat housing (6). Allow antifreeze to drain.
Close draincock (3) and install plug (5).
Fill radiator (2) with antifreeze in accordance with WP 0021 00.
Install radiator cap (1) on radiator (2).
Start engine and allow engine to reach operating temperature (TM 9-2320-302-10).
Allow antifreeze to circulate through cooling system. Check for coolant leaks.
Shut off engine and allow engine to cool.
DO NOT remove radiator cap or drain antifreeze unless engine is cold. Remove radiator cap in two steps.
First, place a thick cloth over cap and slowly turn cap left to first stop. Pause and allow pressure to escape.
Turn cap further left until it can be removed. This is a pressurized cooling system and escaping steam, hot
water or coolant will cause serious burns.
Remove radiator cap (1) and check antifreeze level. Add antifreeze, if necessary, in accordance with WP 0021 00.
Install radiator cap (1).
