Engine Coolant Recycling

^ Tools Required





GM approved Recycling System such as Pro Clean (Available in the GM Dealer Equipment Program)
Whenever the cooling system needs maintenance or repairs, remove and replace the coolant with qualified new or recycled coolant.
If you only drain the radiator, up to 50 percent of the used, contaminated coolant can remain in the cooling system.
Use any of the following methods in order to remove the coolant:
^ Use a waterless coolant evacuation system, available in the GM Dealer Equipment program, or equivalent, that removes the used coolant and replaces the coolant with new or recycled coolant.
^ Use a GM approved coolant recycling system, available in the GM Dealer Equipment program, or equivalent, that recycles the coolant on the vehicle. This eliminates the need for coolant evacuation.

Important: Do not recycle coolant on vehicles manufactured with GM Goodwrench DEX-COOL engine coolant.

^ Recover the used coolant. Store the coolant in a used coolant holding tank. Submit the used coolant for recycling on a regular basis.
