Your engine functions at its best when the oil is between 180 and 200 degrees. Most factory cooling systems, however, maintain fluid temperatures of approximately 200 to 220 degrees, which means the maximum temperature drop it can create in your oil still exceeds the ideal temperature. Installation of an engine oil cooler can solve this problem by working with your factory cooler to provide the necessary additional cooling power.
Types of Coolers
The heat exchanger is the cooler itself, the core that works to maintain proper fluid temperatures. There are three basic types of heat exchangers.
Fluid spreads out over maximum surface area for superior cooling
Plate core can cool a greater volume of fluid faster than other heat exchangers
Stacked Plate Coolers are the most efficient and typically smallest in size
Installation
Cooler Kits
The cooler kits are designed to be mounted flush against either the radiator or the AC condenser core. For maximum cooling ability, the heat exchanger must receive the most airflow possible.
Position A
Mount cooler between your vehicle's grille and the AC condenser core for the greatest efficiency.
Position B
Mounting the cooler between the condenser and the radiator still allows for ample airflow, but cuts effectiveness by 25 percent. Installation of a larger cooler unit in this position may help make up for that loss.
Position C
Mounting the cooler between your engine and radiator considerably decreases the available airflow and causes the cooler to be 40 percent less efficient than if mounted in Position A. It is recommended that you purchase a larger cooler to make up for that loss if using in Position C.
Remote-Mount Units
Ultimate efficiency with high-powered fan mounted to cooler - superior airflow no matter where you mount it
Choice of heat-exchanger core
Tube and fin
Plate and fin
Stacked plate
Remote-Mount Units are great for environments where steady airflow is limited - heavy traffic, off-roading
Oil Line Adapters
For engine oil coolers, installation can be a bit more complex. To access the oil lines, you will need either a spin-on or a sandwich adapter.
Sandwich Adapters mount between engine and oil filter and supply external lines for cooler
Allows oil filter to remain in factory-installed position
Includes thermostatic bypass system (on most models) for quicker engine warm-up and system-pressure maintenance
Please Note:
Both adapters connect directly to the factory oil filter landing, so you will need to determine the exact thread size of your filter before making your purchase to ensure proper fit. If you do not know the thread size, universal kits are available to fit any application.

Keeping Other Systems Cool
Should I be worried about keeping other systems cool too?
Absolutely. Most of Derale's coolers can be used not only for engines, but for transmissions, power steering and fuel systems as well. A power steering cooler will extend the life of both the pump and seal, drastically reducing heat-related pump failures. Installation for power steering and fuel systems requires only the heat-exchanger core and basic accessories.

The trailer hitch I recommend for your 2008 Honda Odyssey is the Draw-Tite Max-Frame #75270 because it doesn't require any fascia trimming (like the etrailer and Curt might). This, as well as the other trailer hitches, exceeds the weight ratings…
If you were going to ask for a transmission cooler recommendation for a 2019 Jeep Grand Cherokee then I would recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit part #D13502 which is going to be the perfect size. The Flex-a-lite…
I did some checking and your 1999 ford f150 5.4l has oil filter threads that are M22x1.5 which means that for a cooler kit you'd want the #D15405 which includes a fitting that matches this size. The cooler that comes with this is a plate-fin…
I cannot speak as to the requirements you will need to keep your 4.6L V8 engine cool after removing the mechanical fan but I can say that mechanical fans draw much more CFM than your average electric fan. The typical mechanical fan can draw anywhere…
The Derale #D15503 Engine Oil Cooler isn't a vehicle specific item. As long as your small block 350 uses an oil filter with 13/16-16 threads with a 3-1/2 inch diameter o-ring, and you have the available space to mount the 16-5/8" wide x…
You are correct, the Derale Engine Oil Cooler Kit part #D15551 that you referenced does come with the correct M22x1.5 thread size that your 1999 Ford F-150 with a 5.4 liter engine comes with so it would work great for you.
The two coolers could easily fit together. Main reason is that the oil cooler kit part #D15450 that you referenced can be remote mounted basically anywhere since it comes with it's own fan. The transmission cooler part #D13504 would then need to…
What is currently running hot? Your transmission or the engine coolant temperature? The #D13504 is designed to cool the transmission, and wouldn't have anything to do with the vehicle's engine running hot, only the transmission. Changing the…
When considering which transmission cooler you want to install on your 2016 GMC Acadia, it is always best to get the largest one that will safely fit on your vehicle. These coolers are both confirmed to fit your vehicle, however, in this case it will…
Good news, I can help you compare the two Derale transmission coolers as well as help you select the right one for your 2009 GMC. The main differences of the two transmission coolers #D13503 and #D13504 are the size and Class number. The #D13503…
In most cases the stock transmission cooler is adequate at best on vehicles when not pulling a trailer. If you are planning on towing 5,000-6,000 lbs you will want a transmission cooler to prolong the life of the transmission in your 2003 Chevy…
The transmission cooler part #D13504 that you referenced is a universal fit cooler that would work well on your 2009 Chevy Silverado. To install it you would want to use the fitting part #D13035. This will snap into the radiator so that you don't…
"WOW! I am impressed! I called to place my order and real person answered, spoke perfect English, albeit a slight southern accent, and my order was sent within a day, shipped quickly and I had it a few days later. I saved over a hundred dollars over local and installed it my self. I cant imagine how that they could do any better. THANKS!"
