TEST AND INSPECTION

WARNING

Protect personnel against any stream of pressurized water from a leak or rupture of a

fitting, hose, or oil cooler during high-pressure air-leak test. Failure to comply may result in

injury to personnel.

1.

Using engine oil cooler core pressure testing kit, see (WP 0081, Figure 5), place rubber gasket

(Figure 3, Item 36), fabricated blocking plate (Figure 3, Item 35), 10 bolts (Figure 3, Item 39), 10 flat

washers (Figure 3, Item 38), and 10 nuts (Figure 3, Item 37) over flanged side of oil cooler element

(Figure 3, Item 31) with threaded hole at inlet opening in oil cooler.

2.

Connect air line to steel plate (Figure 3, Item 35) and apply pressure of 75 PSI (517 kPa) to oil cooler

element (Figure 3, Item 31).

3.

Submerge oil cooler assembly in a container of water heated to 180°F (82°C). Air bubbles in the water

indicate leaks. Replace oil cooler if it leaks.

4.

Release air pressure on cooler assembly. Remove steel plate (Figure 3, Item 35), rubber gasket

(Figure 3, Item 36), and hose from oil cooler element (Figure 3, Item 31).

WARNING

Compressed air used for cleaning purposes will not exceed 30 PSI (207 kPa). Use only

with protective equipment (goggles, face shield, gloves, etc.). Failure to comply may result

in injury to personnel.

5.
