Abstract: The subject invention is an emergency fan belt replacement for use in motor vehicles as a temporary remedial measure to supplant the installed conventional fan belt whenever the latter might fail or otherwise become severed during operations. Specifically, the subject invention is a temporary fan belt replacement, with the same cross-sectional configuration and girth as compared to the conventionally used and installed fan belt. The temporary belt herein has a buckle integrally attached to one end of the belt and which buckle receives the opposite, free end of the belt. Further, such buckle is adapted to shorten or lengthen the temporary belt to conform to the required radial distance between the crankshaft pulley and the pulley for the water pump. The aforesaid buckle is further comprised of clip means to lock the free end of the belt protruding beyond the mouth of buckle so that such free end cannot interfere with the revolutionary movements of the subject belt.
