8 Claims

1. A method of removing and adding thermal energy to a quantity of oil in a prior art internal combustion engine, of the type including but not limited to: an oil pan, oil, a cooling system, liquid coolant, a pump, said method comprising the steps of:

a. removing an oil pan from said internal combustion engine;

b. positioning a heat exchanger in said oil pan, wherein said heat exchanger comprises;

i. a body having a fluid conduit positioned internally thereto;

ii. a first fluid coupler fluidly connected to said fluid conduit;

iii. a second fluid coupler fluidly connected to said fluid conduit; and,

iv. an exchange area connected to said fluid conduit;

c. connecting said first fluid coupler to said cooling system of said internal combustion engine, wherein said cooling system circulates said liquid coolant, and wherein said first fluid coupler acts as an inlet for said liquid coolant into said heat exchanger;

d. connecting said second fluid coupler to said cooling system of said internal combustion engine, wherein said second fluid coupler acts as an outlet for said liquid coolant into said heat exchanger;

e. replacing said oil pan on said internal combustion engine;

f. circulating said liquid coolant through said heat exchanger via a pump in said cooling system, wherein a temperature of said liquid coolant is less than a temperature of said quantity of oil,

g. disconnecting said first fluid coupler from said cooling system;

h. disconnecting said second fluid coupler from said cooling system;

i. connecting said first fluid coupler to a heated fluid source,

wherein said heated fluid source provides a pressurized heated fluid, and

wherein said first fluid coupler acts as an inlet for said pressurized heated fluid into said heat exchanger;

j. allowing said pressurized heated fluid to exit said heat exchanger through said second fluid coupler;

k. wherein said pressurized heated fluid is a gas; and

l. Modifying said oil pan such that said first fluid coupler and said second fluid coupler protrude from said oil pan.
