Derale Power Steering Coolers

  • Cooler and Install Kit
  • With 11/32 Hose Barb Inlets
  • Derale
  • 12-1/4W x 2-1/2T x 3/4D Inch

12-1/4" Wide x 2-1/2" tall x 3/4" deep, tube-and-fin heat exchanger will keep your vehicle's power steering system functioning at its best. All-aluminum construction.


Features:

  • Cuts back on heat-related pump failures
  • Extends the life of both pump and seal
  • Constructed of durable aluminum
    • Thermal-conductive metal provides superior transfer of heat
  • Includes mounting hardware and OEM spec hose
  • Imported


Specs:

  • Inlets: 11/32" hose barb
  • Overall dimensions: 12-1/4" wide x 2-1/2" tall x 3/4" deep
  • Core length: 8-3/4"
  • Distance between inlets: 1-1/4"
  • 1-Year warranty


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. Quick, easy and effective.

Review from a similar Dyno-Cool in Power Steering Coolers


This product is great and installation was not bad at all. Only issue I had was that the GM radiator adaptor should come with this unit when you purchase it for a GM truck. Not as an add-on. Thought I could get it at GM but no go. I Had to work with hoses over 30 min to get them over the fittings even with trans. fluid on the hose and male fitting. So far it looks like trans temp has dropped 30 dg. 134485

Review from a similar Dyno-Cool in Power Steering Coolers


Ive got a 1999 4runner that had the unfortunate luck of having the integrated transmission cooler line rupture inside my radiator. needless to say, the transmission didnt agree very well with having engine coolant running through it and finally died out on me. I bought this transmission cooler to isolate the transmission and the engine cooling systems. The cooler arrived a day ahead of schedule, which is always a bonus. I didnt rate it at 5 stars because I havent had a chance to install it yet and see how it performs, but judging by the reviews that I have read so far, the customer service provided and the prompt delivery, I would say that this transmission cooler will keep my truck running for a good long while. Everything pictured arrived in the box and I have no doubt that it will perform as expected. I will definitely recommend this product and this company to my friends! 30988

Super easy install. With the installation video on Youtube it took out any of the guess work. The hose could stand to be about 3" - 5" longer if you are going to center in the A frame of an older chevy grill (I have an 06 Avalanche. I had to offset to the passenger side to use the supplied hoses) But, you can get a longer hose easy enough. Just ran over the pass and back and no leaks. Looks good so far! 377410

I ordered this cooler for my daughter's 2012 Nissan Rogue to fix CVT transmission heating up causing it to into limp mode. When I got ready to install, I found there was no place to connect the hoses to the transmission. The vehicle only had the direct "bee hive" cooler. Install was delayed while waiting to get a "4 tube bee hive" from a different supplier for an additional $114. 551625

Just got it in the mail the other day. Fast shipping, never have had an issue. Having it installed right now. Feels like it is well constructed and should do the job. We shall see what happens. 18179

What is the rated towing weight for a 1999 Honda CR-V? Does a trannie cooler install fairly easily on the Honda CR-Vs? What is the most effective mounting location for the finned cooler? How does the addition of a trannie cooler effect the volume of fluid and fluid level reading on the dip stick? Thanks for your time and expertise.

The towing capacity question is a loaded one. For that, I would refer back to the owners manual. It can vary depending on engine, transmission, drive configuration and more. Furthermore, Honda has some very specific guidelines regarding towing so it's best to defer to them. Installing a trans cooler on a full size truck can be easier because of the extra space, but it is not particularly difficult on any vehicle. We actually have a video of a cooler being installed on a 2006 C-V. We remove the front bumper cover for the video, but you may find you do not need to. (See link). The most effective location will be in front of both the radiator and the A/C condenser. As you move behind each cooling device, the efficiency diminishes. We put ours in front of everything on the 2006 in the video. For fluid capacity, plan on an extra 1/2 quart. Depending on cooler size and construction, it will vary some, but 1/2 qt. is a good rule of thumb.

Very easy install, absolutely no leaks anywhere in the system after putting it into service. I did have to get additional hose for the install due to the location I chose for the cooler (personal preference). I centered it on the bumper side of the radiator to provide the best air flow. Remember to get a quart of transmission fluid to accomodate the larger system volume after the install. I took my grill off to provide the most room for putting the cooler in rather than trying to wedge it between the radiator and grill, made install the nylon fasteners through the radiator and cooler much easier. Should last for many years. 61081

Hi I need to know at what temp. is exactly activated Thanks
-- comment by: LIVIU - 08/09/2013

This fan does not include a thermostat system. It can be wired into the original electrical system and will then operate according to the thermostat system in the vehicle. It can also be wired to an on/off switch but that is usually only done if off-road and race applications. We have plenty of thermostat options, sold separately, for determining the temperature at which the fan kicks on. For example, part D16735 kicks on at 180 degrees and shuts off at 165 degrees. Part D16759 is an adjustable thermostat system. Turn-on temperate can be set any where between 150 and 240 degrees. The turn-off temperature will always be 10 degrees less than the turn-on temperature.

Review from a similar Dyno-Cool in Power Steering Coolers


After one of use on a 2005 Honda Pilot, everything is holding up just fine. The one star less is because of the difficulty in installing it on this particular vehicle. Although this is a universal component, it is MUCH easier to install on pickup trucks. Best of luck with a brand new rubber hose going on with any sort of ease. 521316


Comments
Our installers typically use some transmission fluid to make installing the rubber hose on the Insta-dapt fitting easier.

I purchased this for my C6 Corvette A6 transmission. I did, however, bypass the radiator and only use the transmission cooler for the C6. I purchased and used the Derale Radiator Adapter fitting 259-13035 for both the top and bottom and just capped them off to keep debris out of the reservoir. I also had to make some custom mounting brackets. This is an excellent product and it keeps the tranny in a great temperature range. 552474

The part itself was easy to install and it does what it is designed to do. Only trouble with installation was with the vehicle, I had to remove part of the front cover on my 09' Avalanche to get to it. Also, I wish I had bought a black one to blend in with the rest of the radiator. 705491

It appears that my transmission temp dropped about 40-60° adding this cooler. The hose was pretty hard to attach to the cooler, even with lubrication. The hose was also to small for my vehicle so I had to source other parts to make it work. I installed it on a 2017 explorer. 661750

Review from a similar Dyno-Cool in Power Steering Coolers


Installed this in a 2017 Honda Ridgeline. Mounted it above the factory cooler that was already in the truck. (Flat fin side towards the a/c condenser). I used the insta-mount zip tie kit and also the flex metal mounts to anchor the cooler to the top of the factory cooler bracket as close to the a/c condenser as possible. The vertical bracket (part of the truck) that runs right down the middle of the a/c condenser has to be cut. All fairly minor fabrication. Hack saw and hand drill stuff. The fan has to be reversed to become a pusher. Followed the hood release cable from the interior to run 12 volts to power the fan on at ignition. Haven’t hooked the trailer up yet so I don’t know if this will resolve the hot tranny situation. ( I could smell the tranny getting hot before especially when we stopped at lights). Change your fluid too. etrailer delivered quickly and the cooler was well boxed and untouched. 656607


Comments
We towed our travel trailer 7500 miles last fall almost coast to coast and back. The trailer weighs 4400 lbs loaded. The Ridgeline’s towing capacity is 5k lbs. I kept our speed at around 65 mph. The truck was capable even in mountain terrain. The transmission never overheated. I did change the fluid once during the trip and again when we got back. The cooler worked. Never once did I get that burning smell. I’m almost certain that the cooler saved us a huge overhaul repair. Thanks etrailer.

  • Recommendation for Power Steering and Transmission Coolers for a 2000 Honda Odyssey
    You will need to measure the inner diameter of the lines to see if it will accept the 11/32 hose barbs on the cooler. If not, you may be able to use the Derale 3/8 Inch Hose Barb to 3/8 Inch Hose Barb Fitting, # D98028. It all really depends on what the inner diameter of the OEM hose is. I am fairly certain Honda also recommends a transmission cooler for towing as well.

  • Can a Leaking Power Steering Cooler be Bypassed Until a New Cooler Can be Installed on a Ram 1500
    You will need to have a cooler that the fluid goes through in order to keep the temperature down. If you do not then the power steering pump will overheat, which is basically the worst thing for it, and lead to damage. In this case a leaking cooler is better than no cooler. If the leak is at a hose or fitting you may be able to temporarily stop the leak using an appropriate product for the leak location.

  • Power Steering Cooler Recommendation for a 2005 Dodge Ram 1500 Crew Cab
    I had a power steering fluid leak on my car and it ended up being a hose issue that was covered under a recall. This may be something you can look into by calling a dealer and asking about open recalls on your year and model Ram. If you do need to replace the cooler I would go with something larger like the Derale 4-Pass Tube-Fin Power Steering Cooler, # D13212. For the most efficiency in cooling, mount the cooler in front of the A/C condenser core in front of the radiator.
