Abstract
A draincock assembly is designed so it may be molded with the radiator tank. The draincock assembly includes a drain for draining fluid from the heat exchanger. The drain includes a cam surface which receives a pin of a draincock therein. The draincock moves rotationally about and axially along a longitudinal axis defined by the drain between open and closed positions in a path defined by the pin moving along the cam surface. A detent is molded to the cam surface and prevents movement of the pin of the draincock therepast unless a rotational force is applied to the handle of the draincock. An O-ring at the end of the cylindrical body of the draincock provides a seal wherein no fluid may exit through the drain nipple until the O-ring moves past the drain nipple, creating a drainage path from the radiator tank.
