Derale Power Steering Coolers - D12213

  • With 11/32 Hose Barb Inlets
  • Cooler and Install Kit
  • Derale
  • 9-1/8W x 2-1/2T x 3/4D Inch

9-1/8" 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: 9-1/8" wide x 2-1/2" tall x 3/4" deep
  • Core length: 5-7/8"
  • 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.

great product easy to install - put it in my 66 mustang as a power assist steering cooler




by:

I was amazed at how quickly I received the fluid cooler I ordered and how well packaged it was. Good job etrailer.




by:

Everything seemed good with this kit. They aren't kidding about the tight hoses- they are tough to get much past the barb...but they do have to be tight to stay leak-less.




by:

Fast shipping and the best customer service. Looking forward to getting the coolers attached and will add some pictures.

Excellent product. Fast shipping!

Review from a similar Dyno-Cool in Power Steering Coolers


I have always loved etrailer and their service. Once again order another of these coolers. Drop my temp from 240 to 170-190 also remember to order extra hose, the adapter if needed for your vehicle make, mount kits. Love it. Perfect this one is on a 07 GMC Yukon XL always add an extra cooler on your 1500 gmc or chevys they help out so much for them.

Review from a similar Dyno-Cool in Power Steering Coolers


Great cooler upgrade for my 1997 GMC Yukon! Little delivery damage, but was so easy to bend those fins back to original shape so no worries!
Nice that you had proper dimension measurements online, so it was easy to figure out what kind I can fit in my truck. Complete kit had everything I needed to get it done!
Modified old cooler bracket little bit and that was it. Works great!

Review from a similar Dyno-Cool in Power Steering Coolers


Not sure of the btu output of this but it worked perfectly fine in my jeep with the factory transmission. Upgraded to a built transmission and as it seems ill need a lot more cooling capacity. No rust or corrosion so far. The clamps it ships with are a gigantic transmission hazzard... had a clamp split right down the middle on me in my drive way thankfully. I would buy different clamps if you didn't want fluid puking out of a hose at 90+ psi and kill your trans.

Review from a similar Dyno-Cool in Power Steering Coolers


I just installed this on my chevy avalanche.
Flipped
the bottom brace around in order to mount to.
The hardest part is getting the hoses on the cooler and over the return line.
I ended up getting a 90 deg quick connection coming from the radiator instead of using the one I got from etrailer. This keeps the hose from bending as much.
Also purchase the installation kit with a hose as you will need an extra hose.
After install I wish I would have went with the next bigger unit which is 10 high instead of 7 1/2 as I had plenty of room.

Review from a similar Dyno-Cool in Power Steering Coolers


good product form a great company !
my
only complaint is this was listed as for my specific truck, but the "insta-dapt" supplied doesn't fit the Dodge truck of my year. even doing my research ahead of time, it seems to be hit or miss whether it would fit as some of them come with 5/16 fittings and some (like mine) come with 9/16 fittings. it doesnt matter the engine size, even other 3.7L dodge trucks of the same year have 5/16 fittings... I think Dodge made a change middle year, but never let the consumer know as mine is a late year '04.
no dig deal as I was able to assemble it anyways and got it up and running great and both the radiator and trans are running much cooler now !
I attached the D12902 to the bumper as you will see in attached images.
2 attached images are just before finishing, bumper hasnt been attached yet, one of them is after everything was complete.

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.


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.

Works well. Just make sure it is matched to the load being towed.

Review from a similar Dyno-Cool in Power Steering Coolers


Can't say anything bad about the unit. It was installed in a Jeep Grand Cherokee that I use to haul trailers occasionally that weigh up to 6000 lbs. So far, I've never overheated the transmission at all, which I attribute to the addition of this cooler. Once again, thanks for a great product.

Review from a similar Dyno-Cool in Power Steering Coolers


I used this cooler on a 2004 Chevy Silverado. The accessories were not needed because I needed longer hoses and fabricated my own mounting. I think the hose clamps and the hoses could be better quality. The cooler does work very well.

Review from a similar Dyno-Cool in Power Steering Coolers


for my 06 colorado with the 2.8l i4. also used the derale trans oil thermostat to help with warmup of trans fluid in winter. trans never gets above 190F now and the engine will overheat (212F) before the trans does. perfect upgrade for a light duty truck/van/car to provide a little bit of cooling at a compact size. very satisfied with the product

Wanted to give my Honda better ability to handle a tow. this baby does the job. Transmission definitely cooler operation since the install. The install was simple and straight forward.

so far so great. Tho sometimes I have to remind the transmission service guys to add a bit more fluid then they are use to.

Review from a similar Dyno-Cool in Power Steering Coolers


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.

Review from a similar Dyno-Cool in Power Steering Coolers


i put this unit in my 2008 NIssan Titan pickup. we are going to take a 9000 mile trip this summer pulling a 27 ft HI Lo camper. The instructions were very generic. specific unit instructions would be very helpful. the grill was difficult to get out until i found a Youtube video for that. the hose provided was to short, so I made a run to the parts store. the unit appears to be well made.


Comments
we used the cooler in my 08 Titan. we pulled a 27 ft travel trailer thru 28 states and never had any issues

Review from a similar Dyno-Cool in Power Steering Coolers


I mounted this fan in the puller position on my auxiliary transmission cooler so that I can tow a 15ft travel trailer with my minivan. Installation was sweet. There was an instruction page in the box and enough parts for mounting. I was surprised at how much air this thing moves. I wouldn't call it noisy since the fan spins smoothly and quietly when I tested it out in the open, but when mounted in the congested grill area of my 2012 Dodge Grand Caravan I can definitely hear it hum more than the stock radiator fan. It pushes that much air. I would definitely recommend this product.

  • Does My Vehicle Need a Power Steering Cooler
    Depending on the vehicle and the driving conditions the vehicle is put under sometimes a power steering cooler is needed, and other times it is not. If when you are driving for an extended period of time you feel the steering wheel get more difficult to turn or it starts to strain then a cooler would be a great choice. Or, if you plan on doing any type of road course racing with the vehicle where the steering will be put under more strain than average daily driving. If the power steering...

  • Does a Power Steering Cooler have to Be Replaced if it Breaks
    Most vehicles do not have a power steering cooler but if your 2003 Chrysler Town and Country came with a factory tow package it could have one. Depending on how it broke you would not necessarily have to replace it. But if it is integrated into the pump or bellows and cannot be bypassed then you would need to replace it. If you tow with the van then I do recommend replacing the cooler with an aftermarket one such as # D12213. It will help cool the fluid down from the added stress of towing.

  • Should 1990 Jeep Wrangler YJ for Trails Use Power Steering Cooler
    It can't hurt to install a power steering cooler on your trailer Jeep Wrangler. Some vehicles don't ever really need them and it doesn't' really help to install them but it won't affect anything negatively. If your steering wheel doesn't get harder to turn after hitting the trails pretty hard or make any whining noise you probably won't see much of a benefit. For the price and potential benefit a cooler like the part # D12213 would be cheap insurance.

  • Power Steering Cooler Recommendation for a 2000 Mazda B3000 Pickup
    Power Steering coolers are not vehicle specific items, so any cooler that fits in front of the radiator or air conditioning condenser on your 2000 Mazda B3000 Pickup would be a good choice. The larger the cooler is the better it will perform so I recommend getting the largest cooler that will fit easily. Measuring is required. The Derale Power Steering Cooler, item # D12213, would be a good choice and you will need an area at least 9-1/8 inches Wide x 2-1/2 inches tall x 3/4 inches deep...

    For as big of a vehicle as you have I would go with a 4 pass cooler like the part # D13212 that comes with an install kit. This cooler measures 8-1/8" Wide x 5" tall x 3/4" deep. I attached an install video for you to check out as well.

  • 2001 Jeep GC Laredo I6 Transmission and Power Steering Cooler Recommendation
    The best way to pick out a transmission cooler for a vehicle is to go with the largest one available that will fit the available space in front of the radiator. The part # D13503 is a very popular option would work well. It measures 11" Wide x 8-3/4" tall x 7/8" deep. The power steering cooler part # D12213 would be a great option as well.

  • Power Steering Cooler Recommendation for 2007 Honda Odyssey
    We do offer a few different power steering coolers in a few different shapes and cooler styles. The most popular and most efficient will be the part # D13212 which is pretty small at 8-1/8" Wide x 5" tall x 3/4" deep and is a 4 pass cooler which means it will provide great cooling power. I attached an install video on a similar Honda Suv for you to check out as well.

    You are right at the capacity of the truck based on the numbers you have provided and if you have other items loaded in the truck that you are not counting with the weight of the truck then you are most likely over capacity. The 1,200 pound weight distribution system you are using could also potentially be overloaded.

  • Transmission, Engine Oil, and Power Steering Cooler Recommendations for a 2006 Honda Odyssey
    If the vehicle manufacturer recommends a transmission cooler, power steering cooler, and/or oil cooler, it is best to follow their recommendation. Even when towing light loads, there will be extra stresses on the vehicles components and it is better to be safe than sorry. For a transmission cooler, a small one will work fine for your application. You can use # D12901. I have included a link to our FAQ article on transmission coolers for you to view.

  • Oil, Transmission and Power Steering Cooler Recommendations for 2003 Acura MDX
    Yes, the aftermarket coolers we sell will provide comparable performance to dealer-installed supplementary coolers. The oil, transmission and power steering coolers we offer are intended to supplement, but not to replace, the standard OEM equipment on a passenger vehicle when it is faced with the demands of towing. The good news is that we offer a number of combination coolers, ones that feature dual cores to allow two different fluids to be cooled simultaneously within one common housing....

  • Trailer Hitch and Wiring for a 2006 Honda Odyssey
    For towing I recommend going with a Class III trailer hitch with a 2 inch receiver for your 2006 Honda Odyssey. The most popular option is Draw-Tite trailer hitch # 75270. I have linked a video showing an example installation. It is a very straight forward install so I am sure you can do it yourself at home. Since you plan on towing I also recommend etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch rise or 4...
