Starline Oil Cooler

Almost one third of the heat generated by the engine must be removed by the vehicle's two cooling systems.Your engine has two cooling systems. 1) The top of the engine: the area around each cylinder in the engine block, the combustion chamber areas in the cylinder head and the intake manifold, dispel heat through the engine's radiator coolant system.(2) The rest of the engine: the crankshaft, bearings, camshaft, lifters, connecting rods and pistons are only cooled by engine oil.The ideal operating range for engine oil is 180øF through 200øF. While operating within this range, the oil works as a lubricant, coolant, and cleansing agent in the engine. Modern engines generally run with radiator coolant temperatures between 200øF and 220øF with oil temperature ranges between 20øF and 75øF Hotter. In other words, when the engine is performing flawlessly, the engine oil is already overheating! Oil that exceeds 220øF rapidly loses its ability to lubricate and cool causing accerlerated fatigue and premature component failure.As oil cycles through tube-and-fin style coolers, heat is extracted through the tubes to the external fins where it is absorbed by the air flowing through the cooler.ÿ In ordinary coolers, the oil nearest the wall of the tube cools quickly, forming a thin, sludge-like insulating layer. The oil flowing through the center of the tube remains hot, never receiving proper cooling.
