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

Jeff Hello everybody, this is Jeff at etrailer.com. Today I'm gonna take a look at this Derale 17" long frame rail transmission cooler, with the 11/32" hose barb inlets. Now this transmission cooler is designed to mount onto your vehicle's frame rail. It'll help improve functioning and overall performance of your transmission. Even helps extend the life of the transmission 'cause it'll help prevent heat related failures. Now, this part will include everything laid out here on the table.
Have the cooler, has the mounting brackets already installed, and the mounting brackets give you a one inch offset to provide a decreased airflow. Now it does also come with this four foot long rubber hose, with the stainless steel clamps for installation. Has this insta-dapt radiator adapter. And then all the mounting hardware you need to mount this cooler to your frame rail. Does have a nice set of installation instructions, it'll describe how it all goes together.
Now this cooler here has built-in turbulators that'll agitate the fluid for more efficient cooling. It's designed with copper tubing, expands into the aluminum fins to give you maximum heat transfer. Basically the copper is the best material for conducting heat out of the fluid, while the aluminum is ideal for transferring and dissipating the heat. Now we mentioned this insta-dapt radiator adapter right here. This will adapt the transmission line so that you can connect your radiator to the transmission cooler quickly and easily.
No cutting or flaring of the lines. This will fit almost any vehicle with the 5/16" diameter transmission lines. And if you notice, the fitting on this includes both male and the female threads. Now these parts are made in the USA. Again, the inlets we mentioned right here, they are 11/32" hose barb inlets.
The distance between those inlets center to center is around 1 and 1/4". Now I do wanna give you some measurements on this. We're gonna do the overall dimensions, so the length from this end right to this end. Let's see, it's gonna be right at 16 and 3/4" long. The height on this is gonna be right at two and 1/2" tall. And then the total depth on this, if we go front to back, do it this way, you can see he is gonna be right at about one and 3/4" deep. Now the distance between the mounting holes on these mounting brackets, you can see the hole here and the hole right over there. So if we put a ruler on that center to center on those mounting holes, is right at 15 and 1/2". But that should do it for the review on this Derale 17" long frame rail transmission cooler with the 11/32" hose barb inlets..

Great for hot rods and muscle cars.Here are some comments and photos regarding the above-referenced order.
The D 13220 Derale transmission cooler was purchased as a replacement cooler
for the primary-transmission cooler for a 2005 Nissan Frontier LE 4WD. This
was done to prevent cross contamination of transmission fluid with engine
coolant caused by a possible rupture of the primary-transmission-cooler core
located in the radiator. Due to numerous consumer complaints regarding this
issue, I decided to take preemptive action and avoid expensive transmission
and radiator repairs. This Nissan also has an auxiliary transmission cooler
located in upper front of the radiator on the passenger's side of the truck.
The Derale cooler was installed on the center of the bumper frame about 2
3/4 inches in front of the air-conditioning condenser. In order to install
the Derale cooler, two strips of steel 7 inches long, 2 inches wide and an
eighth of an inch thick were attached to the bumper frame, see photos
attached. Since the factory-installed auxiliary cooler's outbound hose barb
is just to the left and above the Derale cooler's top/inbound hose barb,
connecting the outbound and inbound hose lines of the two coolers was fairly
easy. The return line hose barb to transmission is just to the left and
almost parallel with bottom/outbound hose barb on the Derale cooler, see
photos attached. Thus, connecting the Derale cooler's outbound line to the
line that returns cooled fluid back to the transmission was also easy.
The primary cooler was by-passed by cutting the outbound line from the
transmission before the connection to the radiator and splicing it to the
inbound line of the auxiliary cooler. The two lines were connected via a
metal tube purchased from a Nissan dealer.
The most difficult part of the installation was attaching the steel mounting
strips to the front bumper frame. Since I do not have an electric welder, I
used liquid steel to make the bonds.
The next step in this process will be to replace the transmission fluid and
filter. The transmission was last serviced at 81k and the vehicle's current
odometer reading is 114k, so it's time for a routine fluid and filter
change. Neither the transmission fluid nor the engine coolant shows any
sign of cross contamination. After 33k, the transmission fluid still has a
red color consistent with replacement fluid I've purchased.
Ideally, in order to insure that the both coolers provide adequate cooling
for the transmission, it would be a good idea to install a transmission
temperature gauge. I understand that most automatic transmissions are
designed to operate at approximately 175 degrees Fahrenheit. However, in
lieu of a temperature gauge, I will monitor the transmission fluid's color
and smell. If the fluid changes color from red to brown or has a burnt
smell, the next step will be to install a transmission pan with added fluid
capacity or replace the factory radiator with one that has dependable
transmission cooling core and connect it as the primary transmission cooler
and have it cool in conjunction the auxiliary and the Derale coolers.
The attached photos were made with the skid plate, spoiler and lower grill
removed. In the photograph labeled Bottom View of Cooler Mount, you may
notice a second hole in the mounting bracket, which is 3 1/4 inches lower
than the actual mounting hole used. A second mounting location was added so
the Derale cooler could be lowered in the event it impeded air flow to air
to the air-conditioning condenser or radiator in a manner that reduces their
operating efficiency. However, so far, the current location of the cooler
has caused no issues.
Please keep in mind that the foregoing comments were made by a retired
accountant - not a mechanic by any stretch of the imagination.
