ABSTRACT:
A cooling unit is provided for an internal combustion engine wherein the latter is provided with a first interior portion having external inlet and outlet ports through which a first liquid circulates and a second interior portion through which a second liquid circulates. The second interior portion is provided with an access opening. The unit includes a base section which overlies the access opening and is sealingly secured to surface portions circumjacent the access opening. The base section is provided with a first set of ports which register with the inlet and outlet ports of the first interior portion, and a second set of ports. Mounted on one side of the base section is a heat exchange section which projects through the access opening into the second interior portion. The exterior of the heat exchange unit is contacted by the circulating second liquid. The interior of the heat exchange section is provided with a passageway through which the first liquid circulates. Mounted on and in sealing engagement with a second side of the base section is a cover section which is provided with a plurality of passages. One of the passages interconnects one of the first set of ports with one of the second set of ports and a second of the passages interconnects another of the first set of ports with another of the second set of ports.
