For the best performance, a radiator fan like Derale 12 Inch High-Output, Electric Radiator Fan, # D16925, should be mounted directly against the radiator. If there is a gap, less airflow will go through the radiator and it will not be as efficient. If you do not want to use the included mounting straps, I would find another way to mount it directly against the radiator for ideal performance. I have included a link to our FAQ article on electric fans for reference. view full answer...
The Derale 4 inch High-Output Extreme Paddle Blade Electric Fan, # D16104, is designed for puller applications only, so the fan must be mounted on the inboard side of the radiator to pull cooler outside air into the engine compartment and over the radiator.
The smallest reversible air flow fan that we carry at this time is the Derale 7 inch Tornado Electric Fan, item # D16617. This fan can be installed as a pusher fan on the forward side of the radiator or as a puller fan on the inboard... view full answer...
The Derale Replacement Push-In Radiator Probe for Derale Single-Stage Thermostat Fan Control, part # D16736, is a thermostatic probe that is inserted into the vehicles radiator and connects to a thermostat switch. The probe will register the temperature of the fluid in the radiator and allow the switch to turn the fan on if the temperature exceeds 180 degrees, and will turn the fan off when the temperature drops to 165 degrees.

Although the Derale 17" High-Output, Electric Radiator Fan-and-Shroud Assembly - 2,400 CFM # D16919 is only designed to work as a puller application (behind the radiator) we do have an option for you.
The Derale 17" High-Output, Electric, Single Radiator Fan - 2,400 CFM # D16217 will work great as a puller or a pusher application (in front of the radiator) like you were wanting. It is worth mentioning that typically fans do work more efficiently as a puller than a pusher.

If there is a fan clutch between the fan and radiator on your vehicle, then you will be able to turn the fan by hand when the engine is off and not running. If there is no clutch, the fan would be difficult to turn because you would have to turn the fan and the pulley, which are turned by a belt.
If the fan is turning freely with no clutch, then there is a problem with either the belt being loose or the pulley will need adjustments. A fan clutch will look like part # D22175, just as an... view full answer...
I reached out to my contact at Flex-a-Lite and was able to confirm that the 16" Flex-Wave Electric Fan # FLX236 does in fact install directly onto the radiator core. The 16" Flex-Wave LoBoy Auxiliary Electric Fan # FLX238 is also a universal fan that installs directly onto the radiator, but it's slightly thinner and provides more air flow at 3,000 CFM, so if you don't need the reversible feature, this is the one I recommend for your 2005 Jeep Wrangler with the 4.0 L V6 engine.

That's a good question, and while there is a thermostatic fan control that allows you to turn the fan on at the temperature you want, the fans are not able to turn on or be controlled independently. The fan you asked about and its control are the following part numbers:
- Derale 25-5/8" Dual High-Output, Electric Radiator Fan w/ Aluminum Shroud and Vents - 4,000 CFM # D16826
- Derale Dual-Fan Adjustable Fan-Control Thermostat with Push-In Radiator Probe # D16788

The Flex-a-lite 15" Black Magic Xtreme Electric Radiator Fan with Shroud part # FLX180 is a universal electric radiator fan that measures 21-1/2" wide x 17-1/2" tall x 4-3/16" deep and can be used as either a push or pull fan. It has a 3,300 CFM rating which will exceed most factory fans. It draws around 18 amps at full power and comes with its own wiring and relay. view full answer...
While the Derale 12" High-Output, Electric Radiator Fan # D16925 is intended to be a pusher fan only unless a custom shroud is made you could reverse the direction of the fan if you reversed the polarity. view full answer...
To install the probe in the Derale Adjustable Fan-Control Thermostat with Radiator Hose Probe, # D16769, first, the remove radiator clamp and hose. Next, insert thermostat probe into the upper radiator hose. Then, place the capillary tube on the radiator inlet tube so the probe itself will remain positioned in the hose. Place the foam pad between the capillary tube and the radiator inlet tube. Then, carefully install the radiator hose and tighten the hose clamp. It is recommended that a... view full answer...
A transmission cooler mounted out in front of the radiator would impede the air flow in a small amount but what we've found is that at higher speeds like that there's enough air flowing through the coolers that the effect is very minimal and nearly all the time not noticeable. view full answer...
Placing an aftermarket cooler such as the Derale Series 8000 Plate-Fin Transmission Cooler part # D13503 in front of your radiator or A/C condenser will minimize the effectiveness of both units however, the amount to which the aftermarket cooler will decrease the functionality of these units is very minimal. Air will still pass through the aftermarket cooler and reach the condenser and radiator thus allowing for an effective operating temperature.
In fact, the recommended location to install... view full answer...
The Derale 26" Dual High-Output, Electric Radiator Fan-and-Shroud Assembly part # D16927 is designed to attach to an existing radiator flange which you can see in the attached photo below. It comes with the needed angled brackets for this as well as everything else you will need for installation. view full answer...
To install and use the part # D15230 on your 2013 Chevy Tahoe will require the part # D15752 for the oil cooler portion and then for wiring the fan you would also need the Derale Remote Mounting Kit, part # D13023. This kit will use an in-line thermostat that will turn on the fan at 180 degrees and automatically turn off the fan at 165 degrees.
You would need the fan to spin the same direction as the fan for your radiator so the two wouldn't be working against each other. To switch the... view full answer...
The Flex-a-lite 16 Inch Trimline Reversible Electric Radiator Fan # FLX11624 referenced in your question can be either a pusher or a puller, depending on how it is wired.
To use the fan as a pusher, the black wire will be the positive/power wire while the blue or red wire is the negative/ground wire. You will also need to remove the fan blade, flip it over, and re-fit to the shaft.
For a puller fan, the blue or red wire is positive while the black wire is negative. The fan blade will... view full answer...
I went ahead and reached out to my tech at Flex-a-lite, and he said that while they cannot confirm the use of the plastic push nuts from the # FLX236 on your condenser, you should be fine as long as you have enough room between the fins of the condenser. You may have to bend/adjust the fins to fit the nuts. You also need to make sure the fan is blowing inward toward the components and not blowing air out of the hood.
As far as making sure you have enough room to mount the fan between... view full answer...
The Derale Thread-In Thermostat Fan Control part # D16730 is a normally open sensor. The sensor is designed to be installed in the radiator and when the fluid reaches 165 degrees fahrenheit that will close the circuit and allow for power to pass through to the radiator fan. view full answer...
I do have everything that you need to use the Derale 27" Dual High-Output, Electric Radiator Fan-and-Shroud Assembly part # D16837 but it does not come with any of the wiring or relays needed to power the fans as Derale stopped including them. It simply comes with the fans, shroud, and mounting bracket/hardware. In order to wire the fan up I recommend using either the PWM Fan Controller part # D16795 or the Derale Dual-Fan Adjustable Fan-Control part # D16788.

I contacted our representative at Derale and he informed me that the Derale Hyper-Cool Remote Transmission Cooler Kit With Fan, part # D13960, can be amounted anywhere. Since it uses a fan for cooling, it is not necessary to use the radiator for cooling as the fan is strong enough to provide cooling power.
It may be beneficial for more cooling efficiency if you can mount it in front of the radiator, behind the bumper, but it is not required. Transmission fluid cannot be cooled too much... view full answer...
Good question; to activate the Derale 14" High-Output, Electric, Single Radiator Fan - 2,100 CFM # D18214 you can use either a manual switch or a thermostatic fan control, both of which we do have. The switch will allow you to simply turn the fan on or off when you deem appropriate, while the thermostatic control engages at its determined temperature, which in the case of this fan and control is 180 degrees.
