Oil Cooler
Oil cooler vs radiator. The oil cooler is based on the same flow through principle as the transmission cooler. Bringing down the temperature of motor oil has many focal points particularly in air cooled engines. It is installed in line with the vehicles oil delivery system. This way it doesnt get too cold in the winter. You only need a tranny cooler if your putting high load on the tranny and it is overheating. Tranny coolers mounted against radiator causing vibration wear and cooler failures.
External transmission cooler vs radiator when purchasing and installing a transmission fluid cooler it is important to factor in running a stand alone transmission cooler or utilizing the factory radiator. Many people choose an oil cooler when their towing application is heavy duty such as towing a fifth wheel trailer or gooseneck trailer. Cooling the oil does a lot towards keeping the engine cool. I believe the oil cooler is actually a separate unit mounted next to the radiator itself. A nice cooler installation mounted with its own brackets plumbed with braided lines makes a nice installation. A good radiator with an adequate built in cooler works well.
Motor oil coolers are small radiators set before the coolant framework on a car that lower the temperature of the oil as it goes through the loops. This results in a physically smaller radiator. It is just operational when the engine is running. In my opinion having the oil cooler is better than not. Oil coolers are optional. Like the radiator the oil cooler is a series of tubes and cooling fins.
The larger the oil cooler the more effective it is at. Coolers can be wide narrow large or small and installed depending on your transmission power and vehicle size. Do i need an oil cooler also. Cooling fins take the oils heat and radiate it to the atmosphere.
