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. The result is longer-lasting oil and a better-functioning engine.

The sandwich adapter in this kit provides the external oil lines necessary to install a cooler without requiring you to move the factory spin-on oil filter, making it even easier to extend the life of your vehicle's engine. In addition, the thermostatic bypass feature allows oil cooler than 180 degrees to bypass the heat exchanger, so your engine will warm up faster.

Recieved item on time, great quality.



by:

Product was exactly as advertised. Product was shipped quickly, very happy with service.



by:

Happy to find a system with the adapter. Mounted to my 4runner very easily. Not much confidence in the plastic mounting method will make something else.



by:

To start I gave the product a good rating only because the kit put together by Derale came with the wrong barb fittings. I called Derale directly and they sent out the right fittings. I have not installed the kit yet but it is well made in the USA. If the kit would of came with the proper barb fitting definitely would of got a excellent rating.



by:

just what i needed easy install nice quality



by:

This is a quality product and performs great. Installed on a 2012 Toyota Tacoma and had to have some machine work accomplished and a change from the original oil filter. Installation was straight forward after those issues were resolved.



by:

Installed this on my 2012 Jeep Grand Cherokee overland with the hemi as the oil temp was heating up while towing. The install was not fun as I had to remove the front fender, grill and under body shield. Had to relocate oil filter to driver side and as a result, ran out of hose and had go out to buy more. Wish there was a few more feet. I placed oil cooler in front of radiator.

Once installed, oil cooler has worked great as I regularly go off-roading and camping towing a 6k pound trailer. Oil temps stay 20-30 degrees cooler making a huge difference when towing. No issues with the oil cooler after a year of use. Has been a great product, I would recommend it.



by:

It has been 1 year now. Here is the story.

Dodge
Ram 1500 5.7 w/3.92 gears.

Oil temp at speed with no trailer: 224
Oil temp at speed with Springdale Mini RV: 240 (backed off at that point….it would have kept climbing)

After the install:

Oil temp at speed with no trailer: 200ish.
With trailer 210-220

Before I did this, I had to keep it at 55 in the expressway to keep my oil from turning into charcoal. Now I can drive normally. Only at the hottest part of the summer on a long grade did I ever brake 230 and it cooled right back off at the top of the hill.

Also holds about another quart of fluid which I like from a wear/tear perspective.

Even if the temp wasn’t an issue this kit would be worth it to move the oil filter to a non-retarded spot. I opted to go with the frame on the right side. Can change filter from side if wheel is turned. Very nice.



by:

My vehicle is a 2010 Ram 1500 5.7 Hemi 4x4. Overall product is great, those Conti hoses are awesome and little hard to get on lol but only issue I had I couldn’t retain my factory mopar oil filter which isn’t a big deal I got a WIX filter that fit. Thanks for quick shipping and great product! Will be buying a transmission cooler from you soon!



by:

Installed this product on my 2013 Ram 5.7 Hemi. Install was simple and straight forward. I hoped there would be improvements in the operating temperature of my engine oil, which there was. Now towing my trailer is no worry about engine oil temp. This cooler works exactly as advertised, and the temp never go above 220. An unexpected result was better gas mileage by almost 2 additional miles per gallon. Also the truck runs much quieter than before and smoother. This noticed by my wife who rides with me always. So I would defiantly call this a win win install and purchase.

This upgrade to my Ram has paid for itself after one year of use by extending the oil life thus reducing oil change interval



by:

I purchased this kit 1 year ago for an 08 Toyota Highlander V6 Sport. The vehicle had a small (and I mean small) trans cooler already installed with the sport, but adding this additional cooler gives us the piece of mind an confidence that when either towing or evening just sitting in temps up to 116F at the drive through in SoCal during summer hours, my family will stay cool. The fans run less and the whole vehicle runs a bit cooler as well. I have verified this with 3rd party OBD readers, actively watching oil temps both at normal operating temps, hill climbs, towing, and when sitting in extreme heat. IT DOESNT BUDGE! I dont have enough good things to say about this cooler. If youve ever thought about it, you should do it. Very easy to install and it flat out works.



by:

It doesn't fit my car even though the website said it would. I had already installed the radiator component before i found the filter adapter didn't fit so i couldn't return the product.

This is a universal kit, so there is no guarantee whether it will fit your application. In order for us to assist you, we need pictures and to know what made the adapter not fit.



by:

Great product. Easy installation.



by:

Easy to install but make sure you use quality thread tape. Check for leakage after 300 miles of driving. Then check again.



by:

Bill is very knowledgeable and answered all my questions. Good fella, I can't comment on the product yet because I haven't installed it yet. Thanks Jesse

Doesn't take long to install.

  • Engine Oil Cooler with Thermostat for a 2006 Toyota Tacoma with V6 Motor
    First you would need an engine oil cooler kit. I recommend # D15502 because it comes with multiple thread types and has the proper O-ring size for a V-6 Toyota motor. The sandwich adapter included is thermostatic so a separate thermostat is not required. Oil that is cooler than 180 degrees will bypass the heat exchanger, so your engine will warm up faster. You may need some extra hose like # D15700 for 10 feet. And for hose clamps use # D13008. I have included a couple of links to oil...

  • Engine Oil Cooler Mounting Location Options for a 1994 Chevy Camaro
    I own a 1998 Pontiac Trans Am and have a very large transmission cooler plus an underhood ram-air kit (Fast Toys Ram Air) that blocks about 50% of the direct air flow that would go through the radiator and I have had no cooling problems. The cooling fans on our F-body cars are very powerful for cooling the radiator fluid and you should not have a problem with airflow through the radiator. Also, our bottom breather style radiators are very efficient. You will notice that most modern cars...

    I have a hitch that will work on your 2011 Ford Flex with single exhaust. The Draw-Tite Max Frame Class III Hitch, # 75679, is a custom-fit trailer hitch that is designed for the 2011 Ford Flex. The hitch has a 400 lbs tongue weight capacity and a 4000 lbs gross trailer weight capacity. I recommend this hitch over the Curt hitch, # 13551, because the Draw-Tite hitch has an easier installation than the Curt hitch on the 2011 Ford Flex.

  • Can a Transmission Cooler Work as an Engine Oil Cooler in a 2009 Chevy Silverado 5.3
    You can use a transmission cooler like an engine oil cooler, however, to make it work properly there are adapters and modifications that will be required.

  • Engine Oil Cooler Recommendation for a 2001 Dodge Ram with 360 Cubic Inch Motor
    The engine oil temperature should only be a concern if you notice that the gauge, if you have a gauge, is above the normal operating temperature. It can also be a concern when towing or carrying things in the bed of the truck. Adding an engine oil cooler will lower the temperature by as much as 50 degrees depending on where the core is mounted. Engine oil temperature should be between 180 and 200 degrees for the engine to function the best so if your engine oil routinely goes above that...

  • How Much Additional Oil Is Needed For Derale Engine Oil Cooler With 10 Feet Of Hose
    I called my contact at Derale and they told me that the engine oil cooler, part # D15502 will hold about 7 ounces of oil. they also said that 10 feet of hose could possibly hold another 7 ounces, so that means the system would total about 14 ounces of oil. A quart of additional oil seems like an excessive amount to account for this cooler system. The instructions say you should install the unit and then start the engine to check for leaks. It then states to check the oil level and add...

A transmission cooler is inexpensive insurance that would do a great job of extending the life of your transmission. If this is the case, a combination transmission/oil cooler would be a good choice. The Derale Combination Transmission and Engine Oil Cooler, part # D15902 might be a good choice for you. The Cooler Kit includes everything necessary...

    Since your 2017 Jeep Patriot has an automatic transmission that is not a CVT then yes, the Derale cooler part # D15502 will work. CVT transmissions don't typically have the external cooler lines like the non-CVT transmissions have so based on that we know it will work.

    Engine oil coolers are not vehicle specific so you can use one on your 1993 Toyota pickup. Cooler # D15502 will fit and includes the fittings you will need. Your motor takes thread size 3/4-16 and has an o-ring diameter of 2-3/4 inches. In most cases the factory oil filter will fit but sometimes a shorter filter is required. For your truck you could use Fram filter # PH3600 or # PH3614. I have included a link to the instructions for you to view.

The O-ring diameter of your filter will better match the adapter of this kit, this kit also has the thread adapter you need 22mm x 1.5mm and the cooler style of this kit is more efficient as it is a plate-fin style, whereas the # D15502 is a tube-fin style that has an o-ring adapter that would be too small.
