MerCruiser Oil Coolers

Oil coolers are typically made of copper or a copper-nickel alloy called cupronickel. The alloy is resistant to corrosion in seawater, as the electrical potential force of the material is adjusted to be neutral with salt water.

Keep your inboard boat's transmission running smoothly with a premium marine oil cooler or oil hose from PartsVu. Oil coolers extend the life of your boat's engine and reduce the chance of overheating under extreme conditions. For example, if you haul a trailer uphill for long distances, then chances are that your engine works at maximum capacity for a long time. This creates a lot of heat that needs a way to dissipate. Cooler oil not only prevents the engine from overheating, but it keeps the oil in better condition as well. Oil degrades more rapidly when it gets too hot; a cooler will make sure it's still in good shape by the time you're ready for an oil change. Oil coolers are a type of heat exchanger which is a mechanism in a marine vessel that uses water from the lake, river or ocean to decrease the temperature of the engine’s coolant in a fresh water cooling system. Many boat owners use a mixture of distilled water and antifreeze that flows through the boat’s heat exchanger and transfers its heat to cycling raw water that is returned to the body of water in which the boat floats much like the radiator fluid in a car transfers the heat to the flowing air. Use quality oil coolers to prevent damage to your boat transmission. Each factor plays a role in deciding which cooler best fits your requirements. A basic rule of thumb is to add as big of an oil cooler as can fit in the available space that receives good airflow, and then add a thermostat so that the oil can be kept in the proper temperature range. Exact replacements for Mercruiser Oil coolers and other Mercruiser engine cooling devices are sold by PartsVu. Boats use oil coolers to keep the engine or transmission oil cool while on the water. An oil cooler is a separate, smaller radiator to an engine's main radiator, which maintains an oil supply at a consistent, optimal temperature. Its purpose is to cool the oil passing through the coils, thus improving the engine and the transmission's lifetime. They are situated in front of an engine's cooling system. Maintain the high-performance of your marine engine with a quality engine oil cooler.
