Motorad T31 coolant recovery tank cap for the 1978-2002 Chevrolet Camaro 2.5L / 2.8L / 3.1L / 3.4L / 3.8L / 4.1L / 4.4L / 5.0L / 5.7L and other vehicles maintains proper cooling system pressure at the recovery tank.
A cracked or warped cap, a damaged seal or dried coolant around the tank neck can mean the cap no longer holds pressure. Before replacing it, look it over with the engine off and cool, since coolant loss can also start elsewhere in the cooling system.
The 1988-1991 Chevrolet C1500 4.3L / 5.0L / 5.7L / 6.2L and the 1988-1991 Chevrolet K1500 4.3L / 5.0L / 5.7L / 6.2L take this cap too, along with a wide range of Buick, Chevrolet, GMC, Oldsmobile and Pontiac models. If your car isn't named here, look it up by year and engine in the "Vehicles it fits" section.
