12-3/4" Wide x 12-5/8" tall x 3/4" deep, high-quality, tube-fin heat exchanger improves the performance of your transmission and keeps it running longer. Premium tube and fin cooler with copper tubing and aluminum fins.
Features:
Specs:
Note: The Derale Insta-dapt radiator adapter fits most vehicles with 5/16" transmission lines, but not all. In some cases, additional fittings or alteration of the OEM lines or hoses may be required for installation.
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. Add to that the unique turbulator technology - whereby fluids are agitated continuously to not only facilitate heat transfer, but also to prevent any undesirable drop in pressure - and you have an easy and effective cooling system.

Hello, everybody. This is Jeff at etrailer.com. Today, we take a look at this Derale Series 7000 tube and fin transmission cooler kit with the hose barb inlets. Now, this transmission cooler kit will improve functioning and overall performance of your transmission. It is recommended for full-sized cars, trucks, and SUVs. This will help extend the life of your transmission and prolongs the period between your necessary fluid changes.
This does cut down on heat-related failures and what's nice is this is designed with copper tubing and expands into aluminum fins for maximum heat transfer. Basically, the copper tubing is the best material for conducting the heat out of the fluid and then the aluminum fins is ideal for transferring and dissipating that heat. The tube and fin design effectively cools a variety of automotive systems. Concept is pretty simple. Basically your fluid runs through the tube and as it travels, as it travels through the core, it transfers the heat out to these fins.
And then these fins is what'll provide the surface area necessary for sufficient heat exchange to take place allowing the heat to be pulled out from the fluid to dissipate into the surrounding air. Also, what's nice is you add the unique turbulator technology on the tubes here whereby fluids are agitated continuously to not only facilitate heat transfer, but also to prevent any undesirable drop in the pressure and you have a nice easy and effective cooling system. Now, what's nice is it's protected from any possible damage during installation 'cause it has these plastic fin guards on it and a nice powder coat finish. It does include everything shown here on the table. It comes with the transmission, the tube and fin cooler itself.
It comes with the four foot long high-temperature OEM spec hose with the stainless steel clamps, the bendable metal mounting brackets with hardware. Also comes with these nylon mounting rods with the different pads to install it. Over here, we have the instadapt radiator adapter and what this does is this will adapt your transmission line so that you can connect the radiator to the transmission cooler quickly and easily. No cutting or flaring of lines. And this will fit almost any vehicle with 5/16th inch diameter transmission lines.
And it does include both male and female threads. Now, these parts are made in the USA. A few specs, we mentioned the hose barbs right here. They are 11/32nd size. The overall dimensions on this, if we measure the width on it and we're gonna measure including the tubes, so from the end of this one to the end of that one is 12-3/4 inches wide. The overall height bottom to the top 12-5/8th inches tall. Total depth on this is only three quarters of an inch deep. Now the core length, which is this is the core right here, so just the length on the core itself is gonna be right about 9-5/8th inches. And the last measurement is gonna be the distance between the inlets right here. These hose barb inlets center to center is gonna be right at 11-1/4 inches. It does come with a nice set of instructions that'll help describe how this all goes together. But that's gonna do it for the review on this Derale Series 7000 tube and fin transmission cooler kit with the hose barb inlets.
