ABSTRACT:
A drain valve for mounting as a replacement for the drain plug in the oil pan of a motor vehicle includes a body member having an upstream end threaded for attachment to the oil pan, a downstream end, and a passageway therethrough normally closed by a valve element adjacent the downstream end thereof. A valve actuator is mountable on the downstream end of the body member to displace the valve element to open the passageway, and the downstream end of the actuator receives a drain hose for directing the oil to a collection receptacle. A dust cap covers the downstream end of the valve between draining operations to protect the valve from damage.
