Method of modifying engine oil cooling system

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, an oil pump, 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, 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;
• (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;
• and
• (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.
