Pressurized air is the preferred method for removing loose debris. Direct the air in the opposite
direction of the air flow. Hold the nozzle approximately 1/4” (6 mm) away from the fins. Slowly move
the air nozzle in a direction that is parallel with the tubes. This movement will remove debris that is
between the tubes.
Pressurized water may also be used for cleaning. The maximum water pressure for cleaning purposes
must be less than 40 psi (275 kPa). Use pressurized water in order to soften mud. Clean the core from
both sides.
Use a degreaser and steam for removal of oil and grease. Clean both sides of the core. Wash the core
with detergent and hot water. Thoroughly rinse the core with clean water.
After cleaning, state the engine and accelerate the engine to high rpm. This procedure will help in the
removal of debris and drying of the core. Stop the engine. Use a light bulb behind the core in order to
inspect the core for cleanliness. Repeat the cleaning, if necessary.
Inspect the fins for damage. Bent fins may be opened with a “comb”. Inspect these items for good
condition:
• welds
• mounting brackets
• air lines
• connections
• clamps and seals
Make repairs, if necessary.
Personal injury can result from air pressure. Personal injury can result without
following proper procedure.
When using pressure air, wear a protective face shield and protective clothing.
Maximum air pressure at the nozzle must be less than 30 psi (205 kPa) for
cleaning purposes.
