Almost 35% of the heat generated by the engine must be removed by the vehicle's two cooling systems.(A) The top of the engine: the area around each cylinder in the main engine block, the combustion chamber areas in the cylinder heads and the intake manifold, dispel heat through the engine's radiator coolant system. (B) The rest of the engine: the camshaft, lifters, crankshaft, bearings, connecting rods and pistons are only cooled down by engine oil.
The ideal operating range for engine oil is 82°C through 93°C. While operating within this range, the oil works as a lubricant, coolant, and cleansing agent in the engine. Modern engines run with radiator coolant temperatures around 93°C and 104°C with oil temperature ranges between 7°C and 24°C hotter. In other words, when the engine is performing flawlessly, the engine oil is already overheating! Oil that exceeds 104°C rapidly loses its ability to lubricate and cool causing accerlerated fatigue and premature component failure.
AROSPEED® oil cooler coils are engineered for maximum cooling efficiency with no restriction in oil flow. Because different engines have varying oil flow requirements, AROSPEED® rates Engine Oil Coolers by engine horsepower and oil flow rates. This results in cooler coil and engine flow rates that closely match.
AROSPEED® Engine Oil Coolers can reduce the oil temperature to between 82°C to 93°C and keep it there. Benefits are:
1) Longer engine life
2) Reduced heat load on engine and radiator
3) Increased oil system capacity
4) Lower under-hood temperatures and more!
If you spend any time in stop-and-go traffic, do any kind of towing, drive in a hot climate, or frequently use your air conditioning, your engine needs a AROSPEED® Engine Oil Cooler!!!
