This homemade tool is made from a radiator cap, a tire valve stem and a rubber plug that fits the radiator ID. The rubber plug is held firmly in place by a gutted radiator cap. Air can be added by a hand pump or very carefully using a compressor. Keep the pressure at or below the original rating for the radiator cap. | This homemade tool is made from a radiator cap, a tire valve stem and a rubber plug that fits the radiator ID.
