Engine Oil Coolers

Quite simple a Liquid Cooled Engines is any type of internal combustion engine that cools down by circulating water during the engine. In today’s high performance engines, cooling must be enhanced. Why do we enhance the cooling of an internal combustion engine? First lets look at the engine and what’s going on inside. At cruising speed, an eight cylinder engine may have over 8000 internal explosions per minute. What that means is that each cylinder will go throughout the four stroke process and fire producing horsepower, torque Power needed to maintain the cruising speed. There’s another beast that’s produced during this process.
Heat. Heat won’t go away without some type of help. Approximately of the heat produced throughout the power stroke is exhausted out from the engine throughout the exhaust stroke. Nevertheless, with temperatures reaching in excess of 2000 degrees and only eliminated that leaves the remaining heat to be absorbed by the internal engine parts, pistons, cylinder heads, valves and the engine block itself and the engine oil. None of those engine parts or the engine oil can withstand unlimited heat, therefore there must be a mechanical means to cool these parts. Most conventional motor oils will break down as a consequence of excessive heat.
Synthetic motor oils have been proven to withstand more heat. Without the cooling of the engine catastrophic failure is guaranteed. This problem was recognized early on. Radiators were manufactured to cool the liquid. Manual water pumps were installed on the engines to circulate the water in an attempt to cool the engine. It didn’t take long to understand that the radiator needed help. Therefore the fan mounted on the water pump was used to either push or pull air throughout the cooling fins of the radiator and cool the coolant and cool the engine. Today it isn’t uncommon to find the newer automobiles with electric fans.
These fans run off an electric thermostat which will start and stop the fan as needed. Engine oil assists in the cooling of the engine also. Engine oil cools itself throughout the circulation process. In many of today’s high performance engines there are oil radiators connected to the radiator. Water will boil at 212 degrees F. Under pressure this temperature will rise before boiling. It had been not too long after this that coolant additives were added to the radiator. This served two purposes, one to help in cooling and the second as a rust inhibitor. Antifreeze, and several after market coolant additives depending upon the concentration will raise this boiling point even more.
