17-3/4" Long x 1-3/4" wide x 2-1/2" deep, heat exchanger mounts on your vehicle's chassis to provide additional cooling to increase the life of your transmission and improve overall functioning. Great for hot rods and muscle cars.

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. And to think - all this cooling power is compact enough to fit on your vehicle's frame rail! Easy, efficient and convenient.

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this Derale 17 inch frame rail fluid cooler with the -6 AN inlets. Now, this cooler will improve the functioning and overall performance of your transmission, your power steering, or even your fuel system. It is designed to prevent any heat related failures and this cooler uses the built-in turbulators that'll agitate the fluid for more efficient cooling. And it is designed with copper tubing that's expanded into these aluminum fins to give you maximum heat transfer. Basically, the copper is the best material for conducting the heat out of the fluid while aluminum's the ideal for transferring and dissipating that heat.
Now this does come with the basic hardware kit for installation. Comes with a nice set of instructions that'll describe how it's installed and it even has the mounting brackets installed, you can see. And they are an offset mounting bracket so when you do mount these, it will offset the cooler about one inch to provide increased air flow. This part is made in the USA. A few specs again on these inlets right here.
They're gonna be a size -6 AN. The distance between those inlets, if we get a ruler center to center, is gonna be right at 1 1/4 inches. Overall dimension from this end to this end, that's gonna be right at 17 3/4 inches long. The height on this is gonna be right about 2 1/2 inches, and the total depth from the bracket to the very front is right at 1 3/4 inches. The distance between your mounting holes, you can see the mounting hole here, and the one here.
If we go center to center on those, is right at 15 1/2 inches. But that should do it for the review on the Derale 17 inch frame rail fluid cooler with the -6 AN inlets..
