Engine Oil Coolers

Why do I need an engine oil cooler?

Your engine functions at its best when the oil is between 180 and 200 degrees. Most factory cooling systems, however, maintain fluid temperatures of approximately 200 to 220 degrees, which means the maximum temperature drop it can create in your oil still exceeds the ideal temperature. Installation of an engine oil cooler can solve this problem by working with your factory cooler to provide the necessary additional cooling power.

Types of Coolers

The heat exchanger is the cooler itself, the core that works to maintain proper fluid temperatures. There are three basic types of heat exchangers.

Cooler Kits

The cooler kits are designed to be mounted flush against either the radiator or the AC condenser core. For maximum cooling ability, the heat exchanger must receive the most airflow possible.

Position A

Mount cooler between your vehicle's grille and the AC condenser core for the greatest efficiency.

Position B

Mounting the cooler between the condenser and the radiator still allows for ample airflow, but cuts effectiveness by 25 percent. Installation of a larger cooler unit in this position may help make up for that loss.

Position C

Mounting the cooler between your engine and radiator considerably decreases the available airflow and causes the cooler to be 40 percent less efficient than if mounted in Position A. It is recommended that you purchase a larger cooler to make up for that loss if using in Position C.

Oil Line Adapters

For engine oil coolers, installation can be a bit more complex. To access the oil lines, you will need either a spin-on or a sandwich adapter.

Please Note:

Both adapters connect directly to the factory oil filter landing, so you will need to determine the exact thread size of your filter before making your purchase to ensure proper fit. If you do not know the thread size, universal kits are available to fit any application.

Keeping Other Systems Cool

Should I be worried about keeping other systems cool too?

Absolutely. Most of Derale's coolers can be used not only for engines, but for transmissions, power steering and fuel systems as well. A power steering cooler will extend the life of both the pump and seal, drastically reducing heat-related pump failures. Installation for power steering and fuel systems requires only the heat-exchanger core and basic accessories.
