- D13018
by:

It looks like from reading the matierl if one is using the cooler in series with the factory cooler this adapter is not needed. Thus I would like to return, but I fear the shipping cost will not make sense, dollar wise... Thus the recommendation should state if you are adding a cooler to your system where one does not already exist, then you'll need this adapter. So if your adding to an already existing system, you do not need the adapter. 23007

  • Recommended Transmission Cooler For 2010 Chevrolet Silverado 1500 5.3L V8 323 Cubic Inch Engine
  • For your 2010 Chevrolet Silverado 1500, I think you are on the right track with the Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13503 you asked this question from. It is 11" wide x 8-3/4" tall x 7/8" deep. For your specific application, I recommend a plate-fin cooler like the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class IV - Efficient, # D13504. This plate-fin style provides increased surface area for the plates to cool faster. This transmission...

  • Heavy-Duty Tow Package for a 2009 Chevrolet Express 1500
  • There will be no wiring differences between the 2WD and AWD models of the 2009 Chevrolet Express 1500 in regards to trailer or brake control wiring. The Curt Class IV Trailer Hitch, # 14090, is an excellent choice for your van. We have an installation video of this hitch on a 2008 model that I attached for you if you plan to complete the installation yourself. The installation will be the same on your Express. For trailer wiring, you will need the following kits: Tow Ready T-One...

  • Recommended Transmission Cooler for a 2017 GMC Sierra 1500 with the 6.2L V8 Engine
  • I spoke to my contact at Derale about adding a transmission cooler to your 2017 GMC Sierra 1500 with the 6.2L V8 engine and they informed me that there should be no problem using one so long as you install it after the factory transmission cooler. I cannot confirm what your truck was or was not equipped with but its sounds like you are referring to a bypass function that reroutes the transmission fluid from the cooler until it reaches a certain temperature. Unfortunately, there would...

  • Best Transmission Cooler for a 2003 GMC Sierra 2500HD with 6.0L V8 Engine
  • For your 2003 GMC Sierra 2500HD with the 6.0L V8 engine, I highly recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit part # D13504. This 8000 series cooler measures 11" wide x 12" tall x 7/8" deep which will be a good fit for your truck. You can expect temperature drops anywhere from 20-30 degrees fahrenheit while using this cooler which will dramatically increase the life of your transmission. Installation is very simple as you can see in the attached video but you will...

  • Transmission Cooler Recommendation for 2011 Chevy Silverado
  • You are a little on the warm side for your transmission fluid. If you can keep it under 200 degrees you will have the max life out of it. That being said transmissions really start to go downhill at 260 degrees. The Derale cooler part # D13503 with the install fitting part # D13018 is the most popular option for your 2011 Chevy Silverado 1500 and would work well. I attached an install video that shows the cooler installed in a similar GM vehicle.

  • Recommended Transmission Cooler for a 2007 Cadillac Escalade
  • The great news is that we do have transmission coolers to help you out. You will have to do some measuring in your engine though to see what will fit. Transmission coolers are universal fit so there is no "exact" fit for your 2007 Cadillac Escalade with a 6.2L V8 Engine. There is a little more into selecting the best transmission cooler than what the size of it is. I am attaching a helpful article that goes over the different kinds of coolers and what their advantages are. One of...

  • Can I Replace The Factory Transmission Cooler on a 2013 Chevrolet Silverado
  • In regards to your 2013 Chevrolet Silverado, if you will be removing the auxiliary transmission cooler then I recommend using the Derale Series 9000 Plate-Fin Transmission Cooler Kit part # D13614 to replace it. This cooler measures 11" wide x 11-3/8" tall x 1-1/4" deep which you should have plenty of space for. In general we recommend that you install the supplemental transmission cooler in-line the factory transmission cooler (in radiator) and the auxiliary transmission cooler (behind...

  • Recommended Transmission Fluid and Engine Oil Cooler for a 2013 Chevrolet Express Van 3500
  • I have exactly what you will need to keep both the engine oil and transmission fluid cool in your 2013 Chevrolet Express Van 3500 but a remote cooler will not be necessary. Instead, I recommend using the Derale Combination Transmission and Engine Oil Cooler part # D15902. As long as you have at least 17" wide x 12-1/2" tall x 3/4" deep of space to mount the cooler behind your grille and in front of your radiator/condenser then it will work well for you. You can expect a drop in engine oil...

The fitting will allow you to quickly and easily install the transmission cooler without having to cut or flare the lines. This transmission cooler measures 11 inches wide, 8-3/4 inches tall and 7/8 inches deep. This is a great plate-fin cooler that will prolong the life of your transmission and improve its overall performance. When...

  • Fitting Adapter Needed to Install Remote Derale Transmission Cooler in 2004 Chevy Silverado
  • The correct fitting for installing a Derale transmission cooler in your 2004 Chevy Silverado is the part # D13018 to install the Derale Hyper-Cool Remote Transmission Cooler # D13960. This cooler has a thermostat as well. You would want to route this from your current radiator's transmission cooler so that it goes through the factory cooler and then finally to this cooler. That is what the fitting allows you to easily do.

  • Can Derale Dyno-Cool Remote Cooler Mount in Front of Radiator in 2010 Chevy Silverado
  • As stated by Derale in the instructions of the Derale Dyno-Cool Remote Cooler with Fan and AN Inlets # D12733, "The purpose of a remote mount cooler is to be able to mount the cooler away from the front of the vehicle therefore not blocking airflow to the radiator/condenser. This cooler can be mounted anywhere space permits." If you are going to be adding a transmission cooler in front of your radiator I instead recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit # D13503,...

  • Transmission Cooler Recommendation for a 2003 GMC Yukon XL 2500 6.0 Liter
  • Adding a supplemental cooler is a good idea, but you do not have to replace the factory one unless there is something wrong with it. You can add an additional cooler to work with the factory cooler for the optimum amount of cooling. When looking at transmission coolers I recommend going with the largest one that will fit in the available space in the engine compartment. There are 3 main locations a cooler can go: the most efficient is in front of the air conditioner condenser core/directly...

  • How to Determine if Transmission Cooler Will Fit In Front of the Radiator on a 1999 Chevy Silverado
  • For transmission coolers you have to go by their dimensions compared to the available space where you want to install it. Stacked plate cooler # D51908 is 13 inches across, 7-7/16 inches tall, and 2 inches deep. If you have more than this much space in front of the radiator then it will fit your 1999 Chevy Silverado. This particular cooler is not a kit so it doesn't come with any hose or mounting components. To mount it you can use # D50020. For hose you can use # D15799 and clamps...

The three types are the fittings that were used are the fitting supplied with the cooler, a snap in style fitting, item # D13035, and the Derale Radiator Adapter Fittings for GM, item # D13018. I believe the last style of fitting is the fitting your truck will need....

  • For your 2004 Cadillac Escalade ESV with the 6.0L V8 engine, I recommend looking at the Derale Transmission Cooler # D13503. This is an excellent plate-fin cooler that will help to prolong the life of your transmission, providing more efficient cooling, especially when towing up those mountain passes. The cooler itself measures 11 inches wide, 8-3/4 inches tall, and 7/8 inch deep. I just recommend making sure that you have the needed space available between the Escalade's grille and...

  • Transmission Cooler Recommendation for a 2003 Chevy Silverado 2500HD
  • You mentioned wanting the best cooler for your 2003 Chevy Silverado. The best, as in the most amount of cooling, is going to be a remote cooler with its own fan like # D13960. It does not matter where this cooler gets mounted because its fan offers the optimum amount of cooling all the time. Otherwise for a standard cooler that would require air flow I recommend # D13105. Its large surface area will provide plenty of cooling for your trucks transmission. To avoid cutting and flaring...

  • Transmission Cooler Recommendation for a 2012 Chevy Traverse

It just makes installation a lot easier if there is nothing in the way. We have not yet installed a transmission cooler on a Traverse so I do not have a video or specific instructions on removing the front clip. When our installers perform an installation they have to determine where the fasteners are that hold on the front clip (if it is a vehicle they...

  • Recommended Transmission Cooler For 1999 Chevy Silverado

This cooler has turbulators inside the tubes to move the fluid and give you superior heat transfer. This will help with the longevity of the transmission as well as helping it function better and is designed specifically for the electronic overdrive transmissions. You will also want the Derale Radiator Adapter Fittings for GM # D13018 so you can add the cooler without the hassle...

  • Transmission Cooler Recommendations for a 1998 Chevrolet Silverado 4X4 5.7L
  • To determine what kind of transmission cooler you will need depends on how much weight you will be towing and where you will be towing. Also, you will want to check how much room you have in front of the radiator to be able to install the transmission cooler. If you will be towing a light load, less than 2000lbs, in flat driving conditions, your 1998 Chevrolet Silverado 4x4 5.7L will do fine with a class I rated cooler. If you will be towing more than a 2000lb load through some hills,...

  • Transmission Cooler for a GM K3500 Pickup Truck with a 6.5 Liter Diesel
  • We generally recommend going with the largest cooler that will fit in the space available in the engine compartment. The Most popular cooler for the K series with the 6.5 liter is # D13503 that you have referenced. It measures 11 inches wide, 8-3/4 inches tall, and 7/8 inches deep. You can get more cooling efficiency using a stacked plate cooler. I would go with # D13403. Even though it is smaller the stacked plate design is more efficient so it is rated higher than the plate fin coolers. You...

  • Here are some of the fittings that I have available that are used to connect a transmission cooler to a radiator on a 2007 Chevy Tahoe. You might want to try and measure the fitting size that is on your vehicles radiator. The Derale Insta-Dapt Radiator Adapter, # D13004, is used in the transmission coolers that we sell. It is a radiator adapter that fits most vehicles with 5/16 inch transmission lines. The Derale Radiator Adapter Fittings for GM, # D13018, are 5/8 inch inverted flare...

  • Will a 3/8 Hose Fit an 11/16 Inch Fitting to Install a Transmission Cooler on a 2006 GMC Sierra
  • There is a lot of pressure within the transmission lines of a vehicle, including your 2006 GMC Sierra so the tighter the fit the better. If an 11/32 inch hose is needed then I would go with it over a 3/8. Cooler # D13503 isn't really large enough or efficient enough to allow you to bypass the factory cooler. That is why I recommend installing the cooler as a supplemental unit. If the fitting on your radiator has a 5/8" hex head then you can use special fitting # D13018 and not have to...

This is a great cooler that will help get your transmission fluid down to a temperature that will help prevent premature failure. You will also need to use the fitting part # D13018 so that you don't have to do any cutting or flaring of metal lines.

Also, you will also want to measure the area in front of the AC condenser to see what size cooler will fit on your 2007 Chevy. I am sending a link to a FAQ page that will give you information on transmission coolers. The GTW rating is the Gross Towing Weight capacity. This is the weight of the trailer, including the load in the trailer. This will help...

  • Good call trying to reduce your transmission fluid temperatures. The cooler the fluid is the longer the transmission will last. The best way to pick out the best cooler for a vehicle is to measure the area in front of the radiator/ac condenser and select the largest cooler to fit there. It also helps to get a stacked plate style cooler as they are the most efficient and pretty small in size. I attached a link to a page that has all of the stacked plate coolers we offer. I also attached...

I attached an install video that shows it being installed in a similar larger GM SUV. You would also want the fitting part # D13018 so that you don't have to cut any metal lines.

For a fitting that would allow you to install the cooler without having to cut or flare any lines you would want the part # D13018.

I would recommend measuring the available space so you know what size cooler to look at. For your 2009 GMC Yukon XL SLT with the 5.3 liter engine, I would recommend using the Derale Transmission Cooler, # D13504. This is a class IV cooler...
