I have a 99 Ford F250 4WD 7.3 diesel with 191,000 miles. I am on my 4th transmission. I pull a horse trailer once a year to Colorado or Wyoming from E Texas on an elk hunt. Other than that, maybe a camper or horse trailer hauled to my deer lease 100 miles away. I finally added a temp gauge to the last one. Now I was seeing that my tranny was running around 205 just pulling my trailers up a small grade around my county. Outside temp around 90. I replaced the original Ford cooler with one from Ford. Same results. I did research on my own and stumbled on to Etrailer.com and articles of the Derale 8000. I had this put on by my radiator man. He wanted to mount it above the Ford cooler to get max airflow. He had to fabricate some brackets and use some other hose connectors as the ones furnished didn't fit right. Not a problem for me as this thing has finally solved my problems. I ran the same route with my horses loaded in the trailer(est 6000# total wt). The temp gauge registered 170 to 175. That is a drop of 30 to 35 degrees. I now feel confident when I go to Colorado in a few weeks that I won't be broke down on side of road with overheated tranny and buying another tranny when I return. Etrailer shipped product very fast. I am overly happy regardless of it not just fitting perfect. 283042

I installed the Derale D13503 in series with my existing factory installed auxillary cooler for added protection on my Ford Explorer Sport Trac. With the Sport Trac tranny having the reputation for overheating failure, I took the cooling up a notch! I tow a 7X14 enclosed v-nosed trailer, and now I am protected! It was a very easy install, and the included hardware made it pain-free :-) 33186

  • Transmission Cooler and Adapter Fitting for 2012 Ford Expedition
    You have to measure inside diameter. In most cases the two sizes are 3/8 and 5/16 inch especially on a vehicle like yours. Instead of using those adapters though we have the part # D13025 which will fit in place of the fittings on your radiator to connect to the cooler lines of a cooler like the part # D13503 which would work great. The hose that comes with this is 5/16 inch.

  • Transmission Cooler Routing Recommendation on a 2002 Ford Super Duty Truck
    Yes, you could use the Derale Radiator Adapter Fittings for Ford, part # D13025, to allow you to use Derale Series 8000 Plate-Fin Transmission Cooler Kit, part # D13504, with the factory cooler that is on your 2002 Ford Super Duty truck. You would want to route the Derale cooler after the factory cooler. By that I mean you would want to run the transmission coolant line from the transmission, to the factory cooler, then to the # 23785, and finally back to the transmission cooler. Routing...

  • Will Derale 8000 Transmission Cooler, # D13504, Fit A Ford F350 7.3L Diesel With Factory Cooler
    The best location for the Derale Series 8000 Transmission Cooler Kit, # D13504, on your Ford F350 7.3L Diesel would be between your vehicle grille and the air conditioning condenser. This location will give you the most airflow and allow the maximum cooling ability of the heat exchanger. You will want to measure to make sure you have clearance to install the heat exchanger. The heat exchanger measures 11 inches wide x 12 inches tall x 7/8 inch deep. The Derale Series 8000 Transmission...

  • Recommendation for a Supplemental Transmission Cooler for a 2007 Ford F-150 with 5.4 Liter Engine
    Based on the information you have provided, which I greatly appreciate, a standard supplemental cooler should be sufficient for your needs. Ideally you want the transmission temperature to be no more than 200 degrees F. Mounting a larger cooler directly behind the grille (in front of everything else) such as # D13504 should get you to the ideal range. You will also want fitting # D13025 so you will not have to cut and flare any lines. A remote cooler with its own fan will provide the...

  • Does Installing Transmission Cooler on 2003 Ford Expedition Require Special Fittings
    For some vehicles we do have fitting adapters that thread into the radiator so that you'll have a barb fitting for the lines of the transmission cooler to attach to. We do not have any for your 2003 Ford Expedition though. Check out the install video I attached for the Derale part # D13503 on a very similar 2001 Ford Explorer and you'll see how we installed it without needing the adapters.

  • Transmission Oil Coolant Return Line Location and Transmission Cooler for a 2000 Ford F-250
    I spoke with a local Ford dealership and found out that the return line from your factory cooler is indeed the one that is run to the rear of the transmission on your 2000 Ford F-250. You are correct, it is recommended that you install a transmission cooler in the return line of the factory transmission cooler. I would recommend the Derale Cooler, part # D13105, as the transmission cooler for your F-250. You will need a Derale Radiator Adapter Fitting for Ford, Lincoln and Mercury,...

  • How to Tap into Transmission Fluid Return Line on a 2012 Ford Expedition for a Transmission Cooler
    The line that you will need to tap into is the transmission fluid return line. The easiest way to determine the return line on your 2012 Ford Expedition transmission is to start the truck, shift into drive but do not go anywhere. After about 15 seconds or so put the truck back in park and apply the emergency brake. Turn off the truck. Out of the 2 hoses attached to the transmission, one should be warmer than the other. The one that is cooler is the return line. You can use radiator adapter...

  • Special Fitting Needed to Install Supplemental Transmission Cooler on a 2011 Lincoln Navigator
    You are correct. Fitting # D13025 threads into the radiator on your 2011 Lincoln Navigator so you will not have to cut or flare the metal lines to install a supplemental cooler. A cooler such as # D13503 includes the hose, clamps, and hardware to mount it so the fitting # D13025 is the only other part you'd need. They are the appropriate size to match the lines to/from the transmission. The fluid will flow from the transmission, into the stock cooler located inside the radiator, then...

  • Hose Size and Fittings to Install a Transmission Cooler on a 2010 Ford F-150 4.6 Liter
    The type of fitting to use will depend on the thread type used on the transmission line fittings on your 2010 Ford F-150. If they are 1/2"-20 threads use kit # D13024. If they are 5/8"-18 use # D13025. If you can measure the diameter of the threaded part of a fitting on your truck that will tell us which one is correct. If you are getting a kit such as # D13504 then the proper size hose is included. The standard hose is 11/32 inches inner diameter.

  • How to Add Transmission Fluid After Installing Transmission Cooler on a 2003 Ford Explorer
    I wasn't sure why your transmission fluid can only be filled by a dealer. Your 2003 Ford Explorer uses one of two possible automatic transmissions used on Ford Explorers from 1997 to 2010 and a lot of other vehicles within that same time frame. So I checked the owners manual and found out that it doesn't have a dip stick to check the fluid so you would not be able to add any. Basically what you would have to do is have a Ford technician perform the transmission cooler installation. Whether...

    The Derale Radiator Adapter kit # D13025 is intended to connect to 5/8-inch fittings in the radiator of your 2007 Mountaineer. These parts then allow hose connection to the supplementary cooler you're installing, such as Series 8000 Plate-Fin Transmission Cooler # D13504. Please refer to the linked review video that shows this cooler installed. Please send along a photo of the harness end you are referring to and we can assist further.

  • Is Larger Transmission Pan Needed if Installing Supplemental Transmission Cooler on 2002 Ford F-350
    No, you will not have to install a larger transmission pan if you added a supplemental transmission cooler though you may need to add more transmission fluid. This is because the core of the new cooler and the hose to add additional capacity. But a larger pan is not needed.

  • 2001 Ford F-350 Transmission Cooler Recommendation
    My recommendation would be to supplement your current transmission cooling system with an aftermarket transmission cooler. For your 2001 Ford F-350 I would suggest the Derale Transmission Cooler part # D13504. This part will require an adapter fitting part # D13025 for installation. Transmission coolers are not vehicle specific, however to optimize efficiency you would want to use the largest transmission cooler available, and mount in the optimal place on your vehicle. The most efficient...

  • Best Towing Enhancements for a 2013 Ford F-150 with 5.0L V8 Engine

This tuner can provide you with a boost in horsepower up to 24 HP and torque up to 24 TQ. The towing tune built into the device will adjust shift points for prolonged transmission life and maximize fuel pressure for increase fuel economy.

  • Comparing the Derale 7000 and 8000 Series Coolers for a 2000 F-250 with the 7.3L V8 Diesel Engine
    The Derale Series 7000 Transmission Cooler Kits like part # D13105 has a tube-fin design whereas the Derale Series 8000 Transmission Cooler Kits like part # D13503 has a plate-fin design. The plate-fin design is superior to the tube-fin design in that it has internal turbulators to help the oil cool faster and prevent pressure loss. For your 2000 Ford F-250 with the 7.3L V8 Diesel Engine, I recommend using the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13504 which...

As far as other items to consider if you're towing include a transmission cooler kit # D12906 with required adapter # D13025 is an additional upgrade that would help avoid potential overheating issues.

  • Does Transmission Cooler Install for 2004 Ford F-150 Require Hose Fittings

  • Recommended Transmission Cooler for 1999 Ford F-350 with 7.3L V8 Engine
    Thank you for the photo of your sturdy F-350 that is in need of a little TLC in the form of a transmission cooler to help it when pulling those heavy loads. For your heavy-duty application you'll want a high-efficiency cooler that will give your transmission the most temperature reduction possible. This means using the largest Class IV cooler that you can fit in the area in front of the radiator and A/C condenser (if present). The cooler I recommend is the Derale # D13105 that you referenced....

  • Automatic Transmission Cooler and Fittings for a 2006 Ford F-150
    For transmission cooler fittings the 6 or 10AN you see listed on coolers such as # D52506 does not make a whole lot of difference because you would want to look at complete cooler kits rather than just a replacement core. The fittings included with the cooler are already a match for it and for the hose that comes with the kits. I recommend cooler kit # D13504. It comes with a large plate-fin cooler, the means to mount it, some hose, and hose clamps. In order to install the cooler without...

  • 1/2 Inch Hose Barb Fitting to Install Transmission Cooler on a 2005 Ford Expedition
    We have a 1/2 inch compression fitting to go from 1/2 inch line to 1/2 inch NPT barb # D13033. I would actually have the flow go from the transmission, to the factory cooler in the radiator, then from there to the other cooler, and then to the Derale cooler before going back to the transmission. This is the normal way to install a supplemental cooler (at the end of the line). The fitting we have listed for the 2005 Ford Expedition is # D13025 which are 5/8 inch inverted flare fittings.

    When it comes to transmission coolers you will want to choose the largest and most efficient cooler that you have room for in your engine compartment. As long as you have room to install a Derale Atomic-Cool Remote Transmission Cooler, then it will work with your truck. These would be very good coolers for your application because they are high efficiency coolers with 500-CFM tornado fans. You will want to choose the correct transmission cooler for your vehicle based on the size of...

  • Transmission Cooler Recommendation for a 2011 Ford Escape
    I found the expert answer you referenced where Jeff said to check the owners manual for restrictions on towing. He meant that you should check to make sure your vehicle is rated for towing the trailer you are planning on towing from a weight capacity point of view. There would be no restrictions on installing a transmission cooler aside from the available space on your vehicle. You would want the to route the transmission fluid from your factory cooler in your radiator to the aftermarket...

    For towing a trailer like what you mentioned with a 1999 Ford F-150 a supplemental transmission cooler would be a great option that we would highly recommend. Most likely your truck came with a factory cooler but typically they do not do a very good job at all. Especially around the age of your truck. The newer vehicles have better coolers but the older ones are adequate at best for light duty applications. I'd recommend the part # D13503 as this is a very popular and efficient cooler...

  • How Difficult is it to Install a Transmission Cooler on a 2012 Ford F-150
    Transmission coolers are fairly simple to install requiring just a bit of mechanical aptitude and some basic tools. If I had to rate the process on a scale from 1 to 10 with 1 being easy and 10 being hard, I would have to say about a 5. I have attached an install video for you. The process to install the cooler will not be the same as the attached video for your truck but very similar as the process will only differ slightly. As long as you have 11" wide x 12" tall x 7/8" deep of space...

  • Can I tow a 30 ft Dutchmen Travel Trailer with a 2003 Ford Explorer
    To determine if you can tow your 30 ft Dutchmen travel trailer with your 2003 Ford Explorer, you will want to find the towing capacity of your Explorer and compare that to the loaded and ready to tow weight of your trailer. I did some research on your Explorer and found that the Explorer will have different maximum tow ratings depending on how it is equipped. For 2WD models, if you have the 4.0L SOHC engine without a tow package, then the maximum towing capacity of your Explorer...

  • Recommended Brake Controller and Transmission Cooler for 2004 Ford Expedition 5.4L 4×4 for Towing
    The best way to go for steep climbs and down hills is to have a good brake controller for the descent so you can use the manual adjuster as needed to apply brakes to only the trailer and the brake pedal to use brakes for both vehicle and trailer. I recommend a proportional brake controller like the Tekonsha Prodigy P3 # 90195. You will want to make sure you don't overheat your brakes by using them too often, but still use them as needed to maintain control. For the up hill climbs,...

The cooler measures 11 inches wide by 8-3/4 inches tall by 7/8 inches deep. You will also need hose fitting # D13025 so you will not have to cut and flare lines to install the...
