b. Removal.

(1) Remove the top cover (TM 10-3930-243-

12).

(2) Drain cooling system (TM 10-3930-243-

12).

( 3 ) Refer to figure 3 - 9 4 and remove the

radiator assembly.

c. Inspection.

(1) Inspect external condition of radiator.

(2) Inspect mounting hardware for rust and

breaks.

(3) Inspect radiator core and inside of radiator

for scale deposits. Steam cleaning is a preferred

method of cleaning radiator.

(4) Examine each part for cracks or other

damage. Replace or repair a faulty radiator.

NOTE

When repainting the radiator core, use a thin coat of

dull black paint. Ordinary oil paints do not transmit

heat as well.

d. Testing.

(1) If a leak in the radiator cannot be located,

plug the inlet, filler and overflow pipes.

(2) Insert an air hose into outlet pipe and plug

opening.

(3) Immerse the radiator in a vat of water and

apply air pressure at 5-10 psi.

CAUTION

Do not exceed 10 pounds per square

inch, as it may damage radiator core.

e. Installation.

(1) Refer to figure 3 - 9 4 and install the

radiator.

(2) Refill the cooling system to proper level
