The clamping mechanism for securing in place an electric heating element insertable through a frost plug aperture into the coolant passage in the blocks of a water cooled internal combustion engine includes a screw having a head located on the outside of a removable body member carrying the heating element, which body member is adapted to be inserted into the apertures to sealingly close it against leakage. The inner end of the screw extends freely through an opening formed in a bight portion connecting a pair of opposed side walls of a rigid yoke having a length greater than the largest dimension of the aperture and adapted to engage the inner surface of the block around the aperture and is threaded into a nut loosely captivated within the yoke by the bight portion, side walls and detents extending inwardly from the side walls and overlying the bight portion. The yoke opening is so sized and the detents are so arranged that the rigid yoke may be tilted about the screw to enter the block through the aperture. The screw head is shaped to be engageable by a socket driven by a power tool, such as an electric or pneumatic screw driver, for rotating the screw to tighten the clamping means during assembly of the immersion heating element into the engine block.

An automatic measured shot starting fluid assembly (10) injects a predetermined amount of starting fluid into a passageway (11) of a diesel engine. The assembly includes a power source (12) to supply electrical current and a starter motor (14) and solenoid (16) for engaging and rotating the crankshaft of the engine upon receiving electrical current from the power source (12). An ignition switch (18) interconnects the power source (12) and the starter motor solenoid (16) for allowing electrical current to flow upon closing the ignition switch (18). An atomizer (30) is disposed in the passageway (11) of the engine for atomizing the starting fluid into the passageway (11). A measured shot valve (26) is connected to a fluid cylinder (24) for measuring a predetermined amount of starting fluid from the fluid cylinder (24) and injecting the measured amount of starting fluid through a conduit (28) to the atomizer (30). A control circuit (32) interconnects the solenoid (16) and the measured shot valve (26) for allowing current to flow from the starter solenoid (16) to the measured shot valve (26) for a first predetermined interval of time to measure a predetermined amount of starting fluid. The control circuit (32) also prevents current from flowing to the measured shot valve (26) for a second predetermined interval of time between successive measured shots of starting fluid continuously upon closing of the ignition switch (18).
