Perhaps the simplest type of heat exchanger, the tube-fin effectively cools a variety of automotive systems. The concept is simple: Fluid cools as it travels through the core by transferring heat out to the fins. The fins then provide the surface area necessary for sufficient heat exchange to take place, allowing the heat pulled from the fluid to dissipate into the surrounding air. The result is longer-lasting oil and a better-functioning engine.
The sandwich adapter in this kit provides the external oil lines necessary to install a cooler without requiring you to move the factory spin-on oil filter, making it even easier to extend the life of your vehicle's engine. In addition, the thermostatic bypass feature allows oil cooler than 180 degrees to bypass the heat exchanger, so your engine will warm up faster.

- Thanks for asking about a Power Steering Cooler and Engine Oil cooler for your 2007 Toyota 4Runner SR5 V6.
Adding two more coolers is not going to present a cooling issue for your engine/radiator. The coolers allow air to flow through them and will not transfer enough heat to the air going through them to effect the cooling performance of the vehicle's radiator.

- Engine oil coolers are not brand- or model-specific; you can install an oil cooler as large as the space you have available to mount one, which is generally in front of the radiator and/or air-conditioning condenser on vehicles so equipped. With coolers, larger is better. This particular kit is intended for vehicles with an engine block oil filter landing between 2-3/4 inches and 3-1/2 inches. If your vehicle oil filter landing falls outside this range you will need to select an alternate sandw
