A radiator hoist and positioner includes an upright post supporting a rotatable swing arm. An extensible hoist line is mounted on the swing arm. A swivel connects a yoke structure to the hoist line. Rotatably mounted on the yoke structure are two clamp mechanisms; the clamp mechanisms are aligned for rotation. A pair of opposed pad members included in each clamp mechanism are advanced and retracted by an activator mechanism to clamp and unclamp a radiator. A clamped radiator is positioned as desired by rotating the clamp mechanisms, the yoke structure and the swing arm, and by extending or retracting the hoist line.
