Product Description

Antifreeze Extender (MIL-A-53009)
MIL-A-53009 consists of a blend of inhibitor chemicals in a liquid solution that can be used to re-inhibit MIL-A-46153 antifreeze. The inhibitors neutralize the acidic by-products that result from the combustion blow-by gases that leak into the coolant. To prevent corrosion, the inhibitors form protective layers on the metal surfaces of the cooling system. Do not use MIL-A-53009 and inhibited antifreeze together in the same engine cooling system. Overtreatment with MIL-A-53009 and inhibited antifreeze can result in the formation of deposits in heat exchangers. This condition can cause overheating. Refer to Naval Ships’ Technical Manual, chapter 233, for information concerning the required conversion procedures.

Do not use the Antifreeze Extender Additive (MIL-A-53009) with the recycled antifreeze. MIL-A-53009 was designed to extend the service life of MIL-A-46153 and is not designed to be used with recycled antifreeze. Use of MIL-A-53009 with recycled antifreeze may result in compatibility problems.
