Reproduction of the vented radiator overflow jar for all 1978-79 Camaro models. This plastic bottle is manufactured with correct HOT/COLD lines as original and includes mounting screws. Does not include the required non-vented "Engine Coolant Cap" part # 371978. Correct for 1978-79 Camaros but will work on 1980-81 Camaros. The 80-81 original cap will not work on this jug.
