Power Steering

TM 9-2320-273-10

IF YOUR TRUCK WILL BE PARKED FOR A LONG PERIOD OF TIME during

cold weather, have Organizational Maintenance personnel REMOVE BATTERIES

AND STORE THEM IN A WARM PLACE. Fill fuel tanks to guard against conden-

sation. Drain any accumulated water from air reservoirs and fuel filter.

MAKE SURE TIRES ARE PROPERLY INFLATED.

Have Organizational Maintenance personnel CHECK AND SERVICE THE COOL-

ING SYSTEM to make sure your truck is adequately protected against extreme

cold. Make sure that transmission is in neutral and that the truck's tires are block-

ed before you leave the area.

The power steering system incorporates a cooler designed to reduce power steering fluid

temperatures during normal or unusually warm conditions. In extremely cold weather,

the cooler becomes restrictive and must be by-passed to prevent over pressure and poS-

sible rupture of the cooler. NOTIFY ORGANIZATIONAL MAINTENANCE TO PER-

FORM THIS MAINTENANCE WHEN OF TEMPERATURE OR BELOW IS EX-

PECTED.

2-22. Extreme Hot Weather.

During very hot weather you must watch for and guard against your truck overheating.

You may have to alter your driving procedures, remembering that the following types of

operation can cause the truck to overheat:

Continuous high speeds.

Long, hard Pulls.

Continuous use of low gears on steep grades or in soft terrain.

Check water temperature gage and STOP YOUR TRUCK IF YOU NOTE ANY

UNUSUALLY HIGH TEMPERATURE READING. Let the truck cool down.

CHECK THE COOLING SYSTEM, AIR CLEANER, ENGINE OIL LEVEL, AND

RADIATOR FINS FREQUENTLY. PERFORM NECESSARY SERVICES AND

NOTIFY ORGANIZATIONAL MAINTENANCE OF ANY UNUSUAL GAGE

READINGS OR OTHER PROBLEMS.
