Stock Replacement Original GM Correct Black Plastic Cap With White Lettering Fits Other G-Body Applications Your coolant recovery system is a critical part of keeping your Malibu functioning right. Without it, your radiator would simply overflow harmful chemical coolants into the environment when hot while drawing back air once cool. Overtime, this replacement of coolant for air can lead to air bubbles being trapped in your engine block which causes hot spots in the system. This can lead to severe engine damage. Older Malibus required constant observation by literary opening your radiator cap and looking inside your radiator to make sure the coolant was always at the proper level. Your overflow tank cap allows hot fluid to expand into the tank while making coolant level checks easy and quick with no interference to the coolant system. Its internal check valve bleeds any overpressure from the tank into the atmosphere while retaining critical fluid. When the valve closes upon draw back, the cap?s internal valve assists in filtering any air bubbles out of the system. When in doubt, replace that old cap, your coolant system will love you for it.
