DNA Motoring TANK-COL-016 For 1982 to 1992 Chevy Camaro / Pontiac Firebird Aluminum Coolant Expansion Recovery Overflow Tank Bottle 91 90 89 88 87 86

The coolant recovery bottle acts as a reservoir for the engine's cooling system. When coolant pressure exceeds the radiator caps' spring-rated pressure, excess coolant will overflow into the Recovery Tank. Once the engine has cooled down enough, a vacuum is created in the coolant system and the coolant is sucked back into the coolant system.
