A method of modifying the oil cooling system of a diesel engine an engine oil supply outlet located in a horizontal plan includes the steps of removing the original equipment liquid-to-liquid heat exchanger and installing a manifold having an oil outlet port directed to a remote oil cooler and a bypass water passage providing an un-branched flow of water, whereby the flow of oil is directed to a remote oil cooler and the entirety of the flow of water in the bypass water passage is discharged back to the water cooling system of the engine without passing through an oil cooling or water cooling heat exchanger.

1. A method of modifying an oil cooling system for a vehicle having a diesel engine, the diesel engine having an engine block with an engine oil supply inlet, an engine water coolant outlet, an engine oil supply outlet located in a horizontal plane, an oil pump, and a water cooling system with a water pump, the engine having an original equipment liquid-to-liquid heat exchanger in which heat from the oil is transferred to the water cooling system, the original equipment liquid-to-liquid heat exchanger 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 method comprising: (a) removing the original equipment liquid-to-liquid heat exchanger from the engine block;(b) attaching a manifold to the engine, said manifold having an oil inlet port for receiving a flow of oil from the engine oil supply outlet, the manifold further comprising an oil outlet port, the manifold being sized and shaped to match the mounting configuration of the original equipment liquid-to-liquid heat exchanger, the manifold further being configured to position said oil inlet port at the location of the oil inlet of the original equipment liquid-to-liquid heat exchanger and being configured to position said oil outlet port at the location of the oil outlet of the original equipment liquid-to-liquid heat exchanger, whereby the manifold is capable of receiving the flow of oil from the engine oil pump without leakage;(c) mounting a remote oil cooling heat exchanger in a location distal from the location of the original equipment liquid-to-liquid heat exchanger, the remote oil cooling heat exchanger receiving a flow of oil from said manifold and cooling the flow of oil prior to retuning the flow of oil to the engine oil supply,(d) the manifold further comprising a water passage providing an un-branched flow of water, the water passage having a water inlet port and a water outlet port, the manifold being configured to position the water inlet port adjacent the engine water coolant outlet of the engine at the location of the water inlet of the original equipment liquid-to-liquid heat exchanger, the manifold further being configured to position the manifold water outlet port 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 without passing through the remote oil cooling heat exchanger. 2. The method of claim 1, wherein: the vehicle has a front end and a rear end, and the method further comprises mounting the remote oil cooling heat exchanger proximal the front end of the vehicle. 3. The method of claim 2, wherein: the vehicle comprises a radiator for cooling the engine coolant, and the method further comprises mounting the remote oil cooling heat exchanger proximal the vehicle radiator. 4. The method of claim 1, wherein said remote heat exchanger is an air-to-liquid heat exchanger. 5. The method of claim 4, wherein said air-to-liquid heat exchanger is a tube-and-fin heat exchanger. 6. The method of claim 1, wherein: the manifold includes at least one sensor port. 7. The method of claim 1, wherein: the manifold includes a horizontally disposed recess adapted to receive a particulate filter and the method further comprises mounting a particulate filter in the recess, the particulate filter having a filter screen with a mesh size of at least 0.003 inch receiving a portion of the flow of oil from said manifold. 8. The method of claim 7 wherein said filter screen is removable. 9. The method of claim 1, further comprising: mounting an oil filter to receive a flow of oil from the outlet port of the manifold. 10. The method of claim 9, further comprising mounting the oil filter to discharge the flow of oil from the oil filter to the remote oil cooling heat exchanger.
