ABSTRACT:
An automotive crankcase drain plug retainer is formed by placing a relatively thin washer around the drain plug, between its head and the adjacent surface of the crankcase.
A permanent magnet mounted in a casing is connected with a radial tab on the washer by a flexible element. The casing magnetically contacts a crankcase to be drained, having the washer previously installed on its drain plug. The flexible element suspends the drain plug and washer when removed from the crankcase.
