Patent ID: 8887688

Claim:
A method of modifying an oil distribution and cooling system for a liquid-cooled diesel engine, the engine having an original equipment oil cooler cover and an original equipment oil cooler mounted at an original location proximal the upper end of the engine in the engine valley, the engine further having an oil pump for circulating oil and a water pump for circulating coolant, the original equipment oil cooler comprising a liquid-to-liquid heat exchanger, said method comprising: removing the original equipment oil cooler cover and oil cooler from the engine; attaching a modified non-stock manifold to the engine in the engine valley, in the original location of the removed original equipment oil cooler, the manifold having oil supply and coolant supply ports aligning with existing passageways in the engine which supplied oil and coolant to the removed original equipment oil cooler, the oil supply port receiving a flow of oil from the engine oil pump, the coolant supply port receiving a flow of coolant from the engine water pump, the manifold further comprising coolant return and oil return ports aligning with existing passageways in the engine which returned oil and coolant from the removed original equipment oil cooler to the engine; installing an oil cooler at a location remote from the engine; mounting an adapter plate to said oil cooler, the adapter plate having a hot oil inlet port, a cool oil outlet port, a cool coolant inlet port and a hot coolant outlet port; attaching an external oil supply line to the hot oil inlet port of the adapter plate to provide a flow of oil from the manifold to the oil cooler; attaching an external oil return line to the cool oil outlet port of the adapter plate to provide a return flow of cooled, filtered oil from the oil cooler to the engine; attaching an external coolant supply line to the cool coolant inlet port of the adapter plate to provide a flow of coolant from the manifold to the oil cooler; and attaching an external coolant return line to the hot coolant outlet port of the adapter plate to provide a return flow of coolant from the oil cooler to the engine.
