  • Prolongs life of transmission
  • Improves overall performance
  • Prevents heat-related failures
  • Has furnace-brazed aluminum construction and 3/4" wide turbulator plates for more efficient cooling
  • Includes complete mounting kit, OEM spec hose with stainless steel clamps and Insta-dapt radiator adapter
  • Recommended for small to mid-size trucks and SUVs


  • Inlets: 11/32" hose barb
  • Overall dimensions: 11" wide x 5-3/4" tall x 7/8" deep
  • Distance between inlets: 10-1/4"
  • Mounting dimensions: 4-1/2" tall by either 5-1/4" wide or 6-3/4" wide
  • 1-Year warranty

Note: The Derale Insta-dapt radiator adapter fits most Nissan Xterras 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.

One of the more popular cooling systems available, the radiator-style, plate-and-fin heat exchanger provides increased surface area so that fluids can spread out along the finned chambers to cool faster. In addition to the increased surface area, this cooler also features turbulator technology, whereby fluids are agitated continuously, not only to facilitate heat transfer, but also to prevent any undesirable drop in pressure.

Video Transcript for Transmission Cooler Installation - 2007 Dodge Caravan

Today we will be working on a 2007 Dodge Caravan. We will be installing Derale part number D13501. Our first step before our installation is actually going to be removing the air dam here. We have a bunch of small plastic rivets that will have to be removed. Now we have five across the back to do. Our next step is going to be to remove the front clip of the vehicle. In order to do that, we have two screws on the inner fender well. I am going to go ahead and start on the passenger side. I am going to repeat the same process on the driver side. Across the top of the front clip I have a 10 millimeter bolt we are going to remove. We have a couple of push pins. We have two more attachment points to get our front clip removed. There is a bolt here that attaches to this fender well and there is a bolt here that attaches to this fender well. In order to access this one, we are going to remove the headlight bucket to get to it. We are just going to slip our headlight bucket up and out of the way. We will set it over here. You cans see here is our attachment point that we need to get to. Ok, there is one. Now we will get the one on the inner fender well. Before we remove the front clip we are going to go ahead and remove the fog lights. In order to do that, you actually just want to twist and pull. Now we are ready to remove the front clip. 1:41

Now that we have our front clip removed, we need to find a suitable location to mount our external cooler. What I want to do now is do a test fit. But, in order to do that, I am going to remove the current transmission cooler from the radiator support and hold down. As you can see, I can pull that away from the support brackets. I think that will give us enough room to get our tie-downs in. Now that we have our location prepped, what we want to do is prep our new transmission cooler. And to do that, we will remove the caps off the cooler. I am going to take just a little bit of the transmission fluid from the vehicle. I will smear that on the fitting to make it a little easier for our line to get on. Before I put that line on, I want to go ahead and install my clamp. As you can see, we have pushed it all of the way to the neck of the cooler. I can go ahead and bring my clamp around and tighten it down. Ok, now that our clamp is secure, we have essentially prepped our new transmission cooler to be ready to fit on the vehicle. Now what I am going to do is go ahead and mount it in position. And then we will cut our hoses to fit once we make our connections. The upper, right hand corner of the transmission cooler is a perfect location to install it. 3:07

So we will go ahead and take our pads that we will fit in between our transmission cooler and the manufacturer cooler. And I am just going to start my tie-downs to hold the pad in place. Ok, let us go ahead and mount it on the vehicle now. This time I just want to get them started going through and gently work them in. Then I can go ahead and take my caps and put them on the back side. Once I have it firmly in place, I can go ahead and repeat the same procedure for all four tie-downs. Now we have our transmission cooler mounted. I am going to go ahead and cut off the excess from our tie-downs. We are going to set up to make the connection to our OEM steel line. First what I want to do is remove this snap ring. For ease of installation, we have gone ahead and removed the wire connector and just set it out of our way. Here I am going to go ahead and remove this side of our bracket just to give me a little more room when working with our line. 4:20

Ok, now that we have our line free from the vehicle and before I start losing transmission fluid, I want to go ahead and set up my tubing cutter. I can go ahead and start the cutting process. Now that we have separated the two lines, we are going to make our connections with our new hoses. Before I do that, a simple tech tip for just giving yourself a little more grip with the cut line is to actually take your screw driver and flair out the edges of the line you just cut. Now that we have completed that, I am going to go ahead and line up to see where I want to cut my hose. We will go ahead and cut our line to fit. I am going to go ahead and put my clamp on the line. Take my line that we just flared out from the vehicle and work it on to our hose. Now I can go ahead and reposition it on the vehicle and tighten down my clamp. Now that we have our clamp secured, we can reinstall our c-clip on our manufacturer line. That completes one side of our new cooler. We are going to go ahead and repeat the same process for the other steal line that we cut and install that now. 5:38

Now that we have all of our clamps and hoses installed, our new transmission cooler is installed. We can go ahead and start reinstalling the transmission line clamp. What I have done is gone ahead and started my engine. I just want to check all of my connections. Make sure they are not going to leak before we reassemble everything. And now that we have all of our connections checked, we can go ahead and start reassembling. We have completed the installation of our new transmission cooler. Now we need to check fluid levels. First we will take a shot of the dipstick. You can see here our first mark and below is where we need to add. Then our first two holes mark where the transmission level should be when it is cold. And our second two holes mark where the transmission level should be when it is hot. You can see we are just barely above the second cold mark. So we are going to need to add about a quarter or half a quart of transmission fluid to bring it up to the hot mark as it is that time of year. That completes the installation of transmission cooler, part number D13501, by Derale.

I was lucky enough to have Etrailer install this on my Grand Caravan (they made a video). I drove 800 miles towing a 6x12 enclosed trailer with NO problems. It kept my transmission cool towing through the mountains. I have towed smaller trailers with the minivan that made it shift strange. After installation, all better. 17549

The product arrived in a timely manner and was as advertised. The product included all hardware needed to install it onto the vehicle. The only problem I had was identifying the transmission lines and determining which line was the hot side and which was the return side. This was no reflection on the product, but more detailed installation instructions would have been nice. The installation videos on the website contributed greatly to my decision to purchase the product.17382

My tranny fluid was running hot on my 2006 Pontiac Grand Prix GXP. The transmission on these cars is known to not be able to handle the power of the engine too well so I wanted to do anything to help it out. I had this cooler installed to supplement the factory cooler. I am not towing anything so a large cooler isn't a necessity. So far, this cooler is working as I expected, keeping the fluid below 200 degrees with the temperature outside above 100! Though a larger cooler would probably get the temp closer to where I'd like it, there is not much room in the engine compartment for something much bigger on my car.19828

Product was as described on the website. Installation took a few hours - no where near as easy as shown on the installation video - to install on my 2004 Alero. The challenge is that the upper line transmission cooler line is the line you have to route the cooler hoses to and mounting the cooler and getting the lines routed up to the top of the radiotr houseing required removal of the front bumper, loosening the radiator mount (from below the car - there are two wing nuts) and then CAREFULLY drilling a 11/2" hole in the plastic molding that completely covers the front upper portion of the radiator. Then you can route the hoses through the hole. I bought the optional GM fittings and that made connecting the hoses very easy. 17938

  • Troubleshooting Malfunctioning Integrated Brake Controller on a 2006 Ford Truck
  • The early integrated brake controllers, like on your 2006 model, were buggy and had a lot of problems. Most of our customers end up disconnecting them and installing a traditional brake controller. This will require a computer re-flash at your dealership. If not, the truck computer will still look for the factory brake controller and you will have a check engine light. It is not the 7-Way on your truck. If the 7-Way was the problem, you would not get voltage at the 5:00 pin when you manually act

  • Where to Have a Transmission Cooler Installed on a 2005 Chevrolet Equinox
  • We do not have any relationships established with any mechanics or shop. However, any basic mechanic should be able to install this product. Your local Chevy dealer should be able to perform the install or whatever mechanic you use for any maintenance on your vehicles. An oil lube or tire place would probably not be able to perform this install. It is also an install that many of our customers decide to do themselves. It requires little more than basic household tools and a bit of patience. W

  • Which Transmission Cooler is Recommended for a Nissan Frontier with 6,500 Pound Towing Capacity
  • The best way to decide which class cooler you need is to take a look at what you will be towing and where. If you will be towing a light load, less than 2,000 pounds, in flat driving conditions, your vehicle will do fine with a Class I. If you will be towing 6,000 pound load through some hills, I would use the Class III cooler. I prefer the 8000 and 9000 series. They are built a little heavier and are more resilient. The 7000 series are built a little lighter and can be damaged more easily if

For your Vibe, the Derale Series 8000 Class II Transmission Cooler, part # D13501 would be your best choice.

  • I would recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit, item # D13502, for your 1997 Honda CRV. This cooler will be more than adequate for towing the weights you will be towing. You can not cool transmission fluid too much so the larger the cooler is, the better. We have a video installation of this cooler on a 2006 Honda CR-V that will be very similar to the installation on your 1997 model, see link. If you would like a smaller cooler you could go with the Derale Series 8

The ideal place to mount a transmission cooler for maximum cooling efficiency is behind the grill of your 2003 Chrysler Town and Country but in front of the radiator. You will want to measure at the front of your vehicle to make sure there is room to mount part # D13501 as it measures 11 inches wide, 5-3/4 inches tall and is 7

  • Transmission Cooler Recommendation for a 2008 Nissan Quest Towing a 2,800 Pound Trailer

A transmission cooler would be a good addition when towing with any vehicle. The added cooling offered will prolong the life of your transmission by keeping the fluid at the optimum temperature.

  • The Derale Series 8000 Plate-Fin Transmission Cooler Kit, item # D13501, is a Class II efficient transmission cooler and would definitely help the transmission on your JK, but since you are towing 2,000 pounds I would recommend a bit larger Class III cooler like the Derale Series 8000 Plate-Fin Transmission Cooler Kit, item # D13503. You cannot cool transmission fluid too much, so the Class III cooler will provide better cooling when towing and will be good for the transmission around town al

  • The Derale Transmission Cooler Kit, # D13501, would be a great choice for the application you have described. The only gotchyas may be the transmission lines themselves. We do not have any reliable information on which fittings are used on Hyundai vehicles at this time. You should be able to use the insta-dapt fitting included with the cooler for installation. This part will install in the fitting coming out of the oem cooler in the radiator tank, and the return line from the new trans coole

  • Transmission coolers are not vehicle specific, so you can use the Derale Cooler, # D13501. It would be a good choice for what you plan on towing. Your vehicle should not require any special fittings or installation instructions beyond the basic installation method.

  • In most cases the factory transmission cooler in a vehicle is adequate at best. I would recommend you install a transmission cooler such as the Transmission Cooler # D13501 that you referenced on your 2005 Toyota Sienna. You will want to do some measuring to see what will fit in front of your radiator but in most cases you will want to go with the biggest transmission cooler you can fit there. If possible I would put a Derale Transmission Cooler, part # D13504. This cooler measures 11 inches

The general rule is that transmission fluid cannot be cooled too much, so using the largest cooler that will fit is a good idea, especially if towing. The only reason not to add the largest cooler possible, would be if you live in very cold climates where temperatures are below 0 degrees often or

  • Locating Transmission Return Line To Install Transmission Cooler on 2007 Pontiac Vibe
  • The best way to determine which transmission line is the supply and which is the return line is to start the cold motor. Place the transmission in drive for 10 seconds, and return it to Park. Turn off the motor and feel both transmission lines where they exit the radiator. The cooler of the two lines will be your return line.

If you can mount the cooler with the inlet and outlet ports up you will get slightly better cooling performance, but testing has shown that there is only a difference of 2 or 3 degrees from any other position.

  • Recommended Transmission Coolers for 2012 Chevy Traverse Pulling 3700 lb Camper
  • Towing in mountainous areas can be hard on a transmission, so installing a cooler is an inexpensive way to provide protection. The most efficient place to install a transmission cooler is directly behind the grille, in front of the radiator and A/C condenser. We recommend measuring the available space in this area, and then choosing the largest transmission cooler that will fit. The # D13501 is a great choice, but if you have the available space, I would go with the # D13502 which measures 11
