An apparatus for maintaining equipment, such as an engine, in readiness for use while it is otherwise nonoperational. The equipment or engine is of the general type having two or more closed liquid recirculation systems. The apparatus bypasses the usual recirculating pumps in such systems. External supply pumps remove liquid from separate sumps or reservoirs and divert the liquids from passage through the normal recirculating pumps of the recirculation systems. The diverted liquid is conditioned to a predetermined temperature by passage through a heat exchanger where one liquid warms or cools the other. The liquids, pressurized by operation of the supply pumps, are then redirected into the equipment recirculation systems downstream from the respective outlets of the recirculating pumps. The pressurized and temperature conditioned liquids are then forced through the equipment passages in the respective recirculation systems in a manner similar to normal liquid circulation during use of the equipment. This maintains the equipment at a temperature in readiness for use. In cases where one of the systems includes a recirculating lubricant, the apparatus also maintains proper lubrication of the equipment elements during periods in which the equipment is not in use.
