COMPRESSOR OIL COOLER AND ENGINE RADIATOR
When grease, oil and dirt accumulate on the exterior surfaces of the oil cooler and radiator,
the efficiency is impaired. It is recommended that each month the oil cooler and radiator be
cleaned by directing a jet of compressed air, (carrying if possible a non-flammable cleaning
solvent) over the exterior core of the cooler/radiator. This should remove any accumulation of
oil, grease and dirt from the exterior core of the cooler so that the entire cooling area can
radiate the heat of the lubricating and cooling oil/water into the air stream.
Hot engine coolant and steam can cause injury. When adding coolant or
antifreeze solution to the engine radiator, stop the engine at least one
minute prior to releasing the radiator filler cap. Using a cloth to protect
the hand, slowly release the filler cap, absorbing any released fluid with
the cloth. Do not remove the filler cap until all excess fluid is released and
the engine cooling system fully depressurized.
Follow the instructions provided by the antifreeze supplier when adding
or draining the antifreeze solution. It is advisable to wear personal
protective equipment to prevent skin and eye contact with the antifreeze
solution.
