3-6. EXTREME COLD WEATHER.

In extreme cold weather, it is essential that your truck be in top condition, or it will

be very difficult to get the truck started (if it is in poor condition, it may not start at

all). Always make sure that You have carefully performed your PMCS, and be sure to

report any problems to Organizational Maintenance.

Always give the engine extra time to reach its operating temperature range of 165O

195F and the transmission strip heater enough time to bring the control body up to

operating temperature.

For detailed guidance on antifreeze protection, lubrication, electrical system, service,

and other maintenance requirements for extreme cold weather operation, refer to

TM 9-207.

3-7 EXTREME HOT OR HUMID WEATER.

Check the engine coolant level frequently; make sure that you maintain coolant at

proper level. Check cooling system (radiator, hoses, lines) for possible leaks, and notify

Organizational Maintenance of any problems.

Check tires frequently to make sure that each tire is inflated to the proper pressure

(but be very careful not to overinflate tires). Wait until tires are cool before you

adjust their pressures.

Hotr damp weather can cause your truck's materials to deteriorate. Watch for evidence

of corrosion and rust on metals, and for mildew, mold or fungus growth on fabrics.

Clean affected areas carefully and, if necessary, notify Organizational Maintenance of

any needed repairs.

3-8. AFTER FORDING

Always check for sand and mud after you have forded water with the M915 thru

M920. Thoroughly clean the truck. If the fording depth was 21 inches or more, notify

Organizational Maintenance and request after-fording maintenance for your truck.
