Claim Text:
1. A kit of parts for modifying an original equipment oil cooling system for a vehicle having a diesel engine, the diesel engine having an engine block with oil, an oil pump for circulating oil, and a water cooling system with a water pump and water cooling passages disposed in the engine block, the engine having an original equipment liquid-to-liquid heat exchanger in which heat from the oil is transferred to the water cooling system of the engine, the original equipment liquid-to-liquid heat exchanger being imbedded within the engine and having a predetermined mounting configuration, the original equipment liquid-to-liquid heat exchanger further comprising an oil inlet, an oil outlet, a water inlet, and a water outlet each in a predetermined location, the kit comprising: (a) a manifold adapted to be installed in the engine in place of the original equipment liquid-to-liquid heat exchanger, the manifold having an oil inlet port and an oil outlet port, the manifold being sized and shaped to match the mounting configuration of the original equipment liquid-to-liquid heat exchanger such that when the manifold is mounted to the engine, the oil inlet port of the manifold is positioned at the former location of the oil inlet of the original equipment liquid-to-liquid heat exchanger and the oil outlet port of the manifold is positioned at the former location of the oil outlet of the original equipment liquid-to-liquid heat exchanger, the manifold oil outlet port, in an installed position, providing a flow of oil to an external oil cooling heat exchanger mounted in a location different from the location of the original equipment liquid-to-liquid heat exchanger, the manifold further comprising a bypass water passage having a single water inlet port and a single water outlet port, the manifold being configured such that when the manifold is in the installed position the water inlet port of the manifold is positioned at the former location of the water inlet of the original equipment liquid-to-liquid heat exchanger and the manifold water outlet port is operatively attached to the water cooling system of the engine so that the entirety of the flow of water in the bypass water passage is discharged back to the water cooling system of the engine; and (b) an external oil cooling heat exchanger having an external mount configured to mount the external oil cooling heat exchanger in a location different from the location of the original equipment liquid-to-liquid heat exchanger, the external oil cooling heat exchanger having an inlet fitting and an outlet fitting sized to receive the flow of oil from the oil outlet port of the manifold and return the flow of oil to the engine.
