MIL-PRF-62259B
installed in either the inlet or outlet plug. Air shall be injected into the radiator to a pressure of
25 psig (172 kPa) and maintained for five minutes with radiator submerged in water. Suitable
means to accurately measure escaped air shall be provided. Leakage exceeding 3 cc per minute
shall be cause for rejection.
4.3.4 Interface requirements verification.
4.3.4.1 Functional fit. One radiator shall be installed in a vehicle to demonstrate that it is
dimensionally compatible, both as installed and when the engine and cooling fan are operating to
determine conformance to 3.4.1.
4.3.4.2 Assembly. Verification of the requirements of 3.4.2 shall consist of visual
inspection, the use of gages or an applicable method from 4.3 or 4.3.1.
4.3.4.3 Dissimilar metals. The use of dissimilar metals shall be contingent on the use of
suitable protection between them. Verification shall consist of visual inspection or an applicable
method from paragraph 4.3 or 4.3.1.
4.3.5 Support and ownership requirements verification.
4.3.5.1 Safety. To determine conformance to 3.5.1, radiators shall be inspected for
hazardous burrs, nicks, sharp edges, foreign materials or other imperfections that pose physical
danger to an installer or maintenance person. Verification shall consist of visual inspection or an
applicable method from paragraphs 4.3 or 4.3.1. Detection of imperfections or other risks to
physical danger shall constitute failure.
4.3.5.2 Lifting eye. To determine conformance to 3.5.2, the lifting eye shall be tested by
anchoring the radiator on a suitable holding fixture and applying a static load of 300 lbs (1335 N)
on one eye at a time in the normally vertical axis in four directions. (Fore and aft, toward and
away from the centerline of the radiator.) The load shall be applied by means of a cable, chain or
rope pulling through a tension recording instrument accurate to within 5 percent and applying the
load to the radiator lifting eye by means of a hook. The radiator shall then be visually examined
and any failure shown by crack or deformation of the lifting eye or tank of radiator, shall be cause
for rejection (see 6.7).
4.3.5.3 Protective finish. Conformance to 3.5.3 shall be determined by visual
examination, use of a gloss meter, impact testing, or an applicable method from 4.3 or 4.3.1.
4.3.5.4 Coolant level determination. Conformance to 3.5.4 shall be determined by visual
examination of various levels of the total radiator volume capacity, through the radiator filler neck
with the cap removed. Failure of the visual examination to detect any of these coolant levels shall
be cause for rejection.
