This patent describes, for use with an engine block having an interior passage for liquid coolant and having a freeze plug opening in the block connected to the coolant passage, an improved coolant heater assembly covering the opening to selectively warm the engine coolant. It comprises: a cup-shaped and thin walled heater housing having an interior space open at one end and closed at an opposite end. The housing being adapted to have its open end aligned with the opening in the block thereby allowing coolant to pass into the housing interior; an electrical resistance type heating element extending through the interior and having a pair of spaced end portions extending through the closed end of the housing; externally exposed end portions of the heating element outside of the housing defining terminals for selective application of electrical energy whenever coolant heating is desired; an elongated saddle clamp member of sufficient length to be positioned across the opening in the block with its ends engaging edges thereof adjacent the opening. The clamp having a centrally threaded opening; an elongated fastener extending through the closed end of the housing and the interior into threaded engagement with the saddle clamp, thereby securing the housing to the block.
