  • Using Derale Transmission Line Compression Fitting Kit D13031
    We have not had any feedback concerning the Derale Transmission Line Compression Fitting Kit # D13031 being prone to leak. If the outside diameter of your transmission line is 5/16" on your 1995 Jeep YJ then these fittings are going to work for you. To make certain there is no leaking what you can do is use liquid thread tape (Leak Lock) to seak the threads on the components expect for the one that secures the compression ring. You can also use standard thread tape, just make sure it is...

  • Can the Factory Transmission Cooler on a 2005 Chevy Silverado 2500HD be Replaced with Remote Cooler
    It would be best to use a transmission cooler as a supplemental cooler to the factory transmission cooler. But if you have to bypass the factory cooler you will need to plug the input/output outlets at the radiator and use a remote cooler such as # D13960. I have included a link to the installation instructions for you.

  • Fitting Adapter for Transmission Cooler to Go From 5/16 inch Hose to 11/32 inch
    Since you have 5/16 inch lines and the hose that comes with the kit is 11/32 the fitting you need is the part # D13031 which is designed just for this. The cooler can install vertically or horizontally too. Either way will work just as fine.

  • How to Install a Transmission Cooler on a 2016 Honda Pilot with the 9 Speed Transmission
    I spoke to my contact at Derale and although they have not had a chance to physically test their transmission coolers on the 9 speed transmission in your 2016 Honda Pilot yet, I do believe we have an option for you that will allow you to install the cooler. What you are going to want to do is install the Derale Transmission Line Compression Fitting Kit part # D13031 for 5/16" to 3/8" or part # D13032 for 3/8" to 3/8". The compression fitting side will need to be attached to the smooth steel...

  • Recommended Derale Transmission Cooler for 2005 Chevy Venture Towing 1700 lb Tent Trailer
    As a first step, you'll want to consult your owners manual to ensure you're not exceeding the towing or cargo capacity of your van. When choosing a transmission cooler, you'll usually want to choose the largest cooler that will fit in the space available (unless you live in a very cold climate.) The ideal spot to mount a cooler is directly behind the grille, in front of the radiator and a/c condenser. The # D13503 is a bit larger, and if you have the room to accommodate it's 11x8-3/4x7/8...

  • Will Derale # D13503 Transmission Cooler Work on 2007 a Toyota Highlander w/ 3.3L Engine
    The Derale # D13503 transmission cooler isn't a vehicle specific item, so it would work just fine on your Highlander. The transmission cooler would install directly behind the grille, in front of the AC condenser and radiator, for maximum airflow. The cooler would tap into the transmission return line from the radiator to the transmission, the fitting you need will depend on the diameter of the transmission line. For a 5/16 diameter line, use the # D13031 fitting or the # D13032 for a 3/8...

  • Fittings for a Transmission Cooler for a 2016 Volvo V60 Polestar
    Since we haven't had the chance to install a transmission cooler on a 2016 Volvo V60 Polestar yet I am not sure what kind of fitting that your transmission cooler uses. What you can do to ensure that it fits a transmission cooler is cut the fitting off of your hose, measure your hose diameter, and then choose a compression fitting that matches the diameter of your hose. We have one for a 3/8" Line # D13032, a 5/16" Line # D13031, and a 1/2" Line # D13033. You can then filter through our...

  • What Size Transmission Lines are on a 2006 Chrysler Sebring with a 2.7L V6 Engine
    The Derale Transmission Line Compression Fitting Kit is designed to allow for you to connect a rubber hose to a steel line. The lines coming from the transmission are generally steel and the aftermarket transmission coolers will almost always use rubber hoses therefore, a fitting to connect the factory steel transmission cooler lines to the rubber hoses on an aftermarket transmission cooler is needed. The factory steel transmission lines on your 2006 Chrysler Sebring are most likely a...

  • Recommended Transmission Cooler for 2013 Kia Sportage Towing 1500 lb Travel Trailer
    A transmission cooler is not a vehicle specific item. For best results, we recommend installing the transmission cooler directly behind the vehicle grille, directly in front of the radiator and A/C condenser. We recommend going with the largest cooler that will fit in the available space. If you have enough room to accommodate its 8-3/4x11 inch size, the # D13503 cooler would work very well for you. If your Sportage has 5/16 inch transmission lines, I'd also recommend using two of the #...

  • Transmission Cooler Recommendation for a 2006 Chrysler Pacifica
    A transmission cooler is always a good idea if you are towing. Overheating is one of the biggest causes for transmission failure because your transmission relies on the transmission fluid to stay cool. The added stress from towing a trailer on the engine and transmission will cause the transmission fluid to heat up more than normal. It is a good idea to get the largest transmission cooler possible because transmission fluid cannot be cooled too much, however, you will be limited by the...

  • Suitability of Derale Transmission Cooler, Part # D13503, for 2010 Toyota Rav4 Limited V6
    Transmission coolers are not vehicle-specific, so you are free to select any one that will fit into the available space in front of your air conditioning condenser. In the world of coolers bigger is better. The particular Derale cooler you reviewed, the Derale Series 8000 Plate-Fin Class III, part # D13503, is a substantial unit that measures 11 x 8-3/4 x 7/8 inches. This will do an excellent job of cooling your Rav4 transmission. It includes the Derale Insta-Dapt radiator adapter that...

  • Is a Transmission Cooler Required for a 1992 Dodge B250 V8 for Towing a 1500 lb Tent Trailer
    Adding a transmission cooler is never a bad idea. Anytime you are towing a trailer, the engine and transmission have to work harder. Keeping your transmission fluid at a lower temperature will prolong the life of your transmission. One factor that you can look at to determine if a supplemental transmission cooler would be absolutely necessary is the towing capacity of your 1992 Dodge B250. If the weight of your tent trailer is near the towing capacity of your van, I would strongly recommend...

  • Transmission Cooler for 2003 Toyota Tundra with 4.7L Engine
    Transmission coolers are not vehicle specific items, so the idea is to choose the largest, most efficient cooler that will fit in the space available. The best and most efficient place to mount a transmission cooler is directly behind the grille in front of the radiator and A/C condenser. If the space available will accommodate its 11 x 11-3/8 inch dimensions, the Derale # D13614 would be an excellent choice. The fittings needed will depend on the diameter of your transmission lines.

  • Transmission Line Fitting Recommendation for 1984 Chevrolet Silverado 454 Turbo
    The Derale Radiator Adapter Fittings, # D13018, covers 1987 - 2007 Chevy trucks so I can not guaranty that this would work for you. Instead you can use a universal fitting like part # D13031 for 5/16 inch line, # D13032 for 3/8 inch line, or # D13033 for 1/2 inch line. You will just need to take a quick measurement of the line on your 1984 Chevrolet Silverado 454 Turbo to determine which one you will need.

  • Is the Derale Insta-Dapt Radiator Adapter Part # D13004 Needed on a 2000 Volvo S70
    The Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets part # D13501 comes with everything you will need for installation including the Derale Insta-Dapt Radiator Adapter part # D13004 unless your radiator does not accept 1/2”-20 female fittings then you would want to use the Derale Transmission Line Compression Fitting Kit part # D13031 for 5/16" factory transmission lines or part # D13032 for 3/8" factory transmission lines. Unfortunately, there is no real way for me...

  • Recommended Transmission Line Adapter for Derale Plate-Fin Cooler on a 2007 Dodge Ram Turbo Diesel
    I spoke to my Derale contact and he informed me that if your vehicles current lines are steel or aluminum you will need a compression fitting adapter like # D13033 for the # D13502 Plate-Fin Transmission Cooler. You would need to find out what size line you have and choose the corresponding adapter. 1/2 inch line uses the # D13033. For 3/8 inch line you will want the # D13032 and for 5/16 inch line you will need the # D13031. The cost will be listed with each product. I have linked...

  • Recommended Compression Fittings For Dodge Durango 2011 Citadel 5.7L Transmission Cooler
    The insta-dapt comes with all of the Derale kits. It is unfortunately not always a fit as it is a universal adapter. You have a couple options, you can flare the lines you have or I recommend using compression fittings. To ensure you choose the correct compression fitting for your vehicle, you will want to measure the diameter of your transmission lines. The most common size is 3/8 inches, but it would be safe to measure first. I have attached links to the compression fittings that we...

  • Transmission Cooler Recommendations for a 2011 Toyota Corolla
    Both the Derale Series 9000 Plate-Fin Transmission Cooler Kit, # D13611 and the Derale Series 8000 Plate-Fin Transmission Cooler Kit , # D13501, would be a great choice for your 2011 Toyota Corolla. 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...

  • Correct Transmission Line Fittings to Install Transmission Cooler on 2009 Chevy Traverse
    According to Derale, the correct fitting to install the D13504 cooler in your 2009 Traverse would be part # D13035, if the return transmission line is attached to the radiator using an E-clip. You would need two of them. If the connection does not use an E-clip, you would need to use a compression fitting. The correct fitting will depend on the outside diameter of your transmission lines. For a 5/16 inch line use part # D13031, for a 3/8 inch line use # D13032 and for 1/2 inch line use...

    When it comes to transmission coolers, I recommend choosing the largest transmission cooler that will fit into the available space. The ideal place to install a transmission cooler is directly behind the grill, in front of the radiator and A/C condenser. I would recommend measuring the available space so you know what size cooler to look at. For your 2010 Chevrolet Silverado with the 4.3 liter engine, the Derale Transmission Cooler, # D13503, that you referenced would be a good choice....

  • Transmission Cooler Recommendation for a 2006 Toyota Camry 2.4 Liter
    The Derale Series 8000 Transmission Cooler, # D13501, would be a great choice for your 2006 Toyota Camry. It would not hurt if you wanted to step up to the Derale Series 8000 Cooler, # D13502, but it may not be necessary. Cooler # D13501 has a class II rating for vehicle that will be towing up to 3,500 lbs, which is most likely the maximum rating for your vehicle. If you choose to step up to the # D13502 cooler, then you will want to measure to make sure you have space available to install...

  • Transmission Cooler Recommendation for a 2011 Chevrolet Traverse
    For your 2011 Chevrolet Traverse, I would recommend installing the Derale Series 8000 Plate-Fin Transmission Cooler, # D13503. The main difference between this transmission cooler and # D13303 is the design. The plate-fin design is more efficient that the tube-fin design because they force fluid between much smaller plates that agitate the fluid. The fluid leaving the plate-fin style is cooler because the smaller, flatter plates allow more fluid to contact the aluminum surface inside the...

  • 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...
