Engine heater

In combination with a cold, fluid-cooled automotive engine, apparatus for heating said cold engine to facilitate starting thereof, said apparatus comprising:

• an automotive service engine having a pressurized fluid-cooling system;
• first and second fluid conduit segments permanently connected to and in communication with the fluid cooling system of said cold engine;
• coupling means adjacent the outermost ends of said first and second segments for detachably connecting said segments to selectively present a closed fluid loop with said cold engine system, and alternately open-ended conduit segments when said coupling means are detached;
• first and second conduit sections permanently connected to and in communication with the fluid cooling system of said service engine;
• coupling structures adjacent the outermost ends of said first and second sections for detachably connecting said sections to selectively present a closed fluid loop with said service engine system, and alternately open-ended conduit sections when said coupling structures are detached;
• a pair of fluid-transfer conduits of length to span the distance between said conduit segments and sections;
• and
• attachment means adjacent the opposed ends of said transfer conduits for detachably connecting one of the transfer conduits between the coupling means of one of said segments and the coupling structure of one of said sections, and for detachably connecting the other of said transfer conduits between the remaining segment coupling means and section coupling structure, when said segments and sections are detached, in order to define a closed fluid loop with the cooling systems of said cold and service engines, whereby, upon running of said service engine with the cooling fluid therein in a heated condition, such heated fluid is circulated throughout the last-mentioned closed fluid loop for heating said cold engine and for facilitating starting thereof.
