This type of design is most commonly used on gasoline engines that are known to require engine oil cooling capacity.  Engines that are designed to be have additional capacity for recreational towing may require this type of cooling in order to maintain oil temperature during heavy-duty use.

This type of engine oil cooler is designed to be mounted inside one of the radiator tanks.  Oil lines will be routed to the the oil cooler.  Oil will flow through the inside of the oil cooler as cold water in the radiator tanks will flow around the outside of the oil cooler. Optimal performance will be achieved when the oil cooler is mounted in the cold side radiator tank, which is where hot oil and cold fluid (glycol/water mixture) will have the greatest inlet temperature difference.

Most common applications for this design can be found on passenger cars and light duty trucks that are equipped with a factory installed trailer tow package. 

Below are the various styles of engine mounted engine oil coolers that  we currently manufacture.  Each design is tailored to a certain type of application.
