Expert Answers about Flex-A-Lite

  • Transmission Cooler Recommendations for a 1997 Mercury Villager
  • There are 3 common locations for a transmission cooler on a vehicle. You can check them all to see which has the most space. The most efficient location is in front of the AC condenser . The next most efficient is between the condenser and the radiator. And the least efficient is behind the radiator. Cooler # D13502 will take up little space. It is 11 inches across, 7-1/4 inches tall, and 7/8 of an inch deep. You can check those three locations mentioned above to see which has enough...

  • Recommended Transmission Cooler For A 2006 Ford Explorer 4.6L V8
  • Generally speaking, the best transmission cooler to use would be the largest one you have available space for behind the grill and in front of the radiator. The largest available cooler we have as a confirmed fit for your vehicle is the Flex-a-lite Translife Transmission Cooler part # FLX4126. This cooler comes with everything needed for installation except the vehicle specific transmission cooler line fitting part # D13024 and part # D13025. This cooler will work well with your vehicle...

  • Transmission Cooler Recommendation for a 2005 Nissan Murano
  • For about the same price you would be much better off going with the Derale transmission cooler part # D13502 as it is a more efficient style of cooler. It is a plate-fin cooler which does a better job extracting heat than the tube-fin style you mentioned. A transmission cooler is a great insurance policy to prolong the life of a transmission. You definitely want to fix the leak as soon as possible. The difference between the two coolers you mentioned is that the # FLX4112 is 3 inches...

  • Recommended Transmission Cooler For 2010 Chevrolet Silverado 1500 5.3L V8 323 Cubic Inch Engine
  • For your 2010 Chevrolet Silverado 1500, I think you are on the right track with the # FLX41236, you asked this question from. It is 20" wide x 10" tall x 3/4" deep. For your specific application, I recommend a plate-fin cooler like the Derale Series 8000 Plate-Fin Transmission Cooler Kit w/Barb Inlets - Class IV - Efficient, # D13504. This plate-fin style provides increased surface area for the plates to cool faster. This transmission cooler has the turbulator technology that agitates...

  • Thermostat Recommendation for the Flex-a-lite Transmission Cooler with Fan # FLX4190
  • If you wanted the Flex-a-lite Transmission Cooler # FLX4190 to run all the time you would run the power and ground wires of the fan to a power source and ground. The preferred method is to use a thermostat like part # D18735 so that it only comes on when the temperatures get above 165 degrees.

  • Recommended Transmission Cooler For 3/8 Inch Hoses on 2002 Ford Excursion 6.8L
  • For your 2002 Ford Excursion 6.8, I recommend the Flex-a-lite Translife Transmission Cooler - Tube and Fin - Barbed Fitting - Class V # FLX4126. This is a tube-fin cooler that has turbulators inside tubes for superior heat transfer. It is 20 inches wide, 10 inches tall, and 3/4 inches deep. This kit comes with the hoses, fittings, and nylon nuts and bolts for mounting. I also recommend the Cooler Guard for Flex-a-lite 10" x 20" Transmission Cooler # FLX4126G. The included mounts attach...

  • Difference Between Flex a Lite Transmission Cooler FLX4118GMT and FLX41186GMT
  • The picture may not reflect the actual difference but the part # FLX41186GMT uses 6 AN fittings and the # FLX4118GMT uses standard barbed fittings. What's interesting is that the AN fitting of the # FLX41186GMT has a barb attachment on it.

  • Best Transmission Cooler for a 2009 Chevrolet Silverado 6.6L Duramax with Allison Transmission
  • The Flex-a-lite Translife Transmission Cooler part # FLX4126V will physically fit your 2009 Chevrolet Silverado with the 6.6L Duramax diesel engine as long as you have 20" wide x 10" tall x 3/4" deep of space in front of your radiator/condenser behind your grill. However, Flex-a-lite does not recommend using one of their coolers with the Allison transmission due to potential loss of pressure. We have confirmed with Derale that the use of their transmission coolers will not create a...

This cooler has 3/8 inch barbed fittings and 1/2 inch tube diameter with an 8 pass configuration. It has built in turbulators to move the fluid and assist with better heat transfer for more efficient cooling. The position you mentioned is based on the options on your vehicle.

  • How Are Coolant Lines Run When Installing Transmission Cooler
  • I have attached a drawing that shows how the transmission cooler lines are routed. You have a line that runs from the transmission and sends the hot fluid to the radiator. There is anoth er line that runs from the radiator after it is cooled back to the transmission. When you install a summplemental cooler like part # FLX4118-6 you use the line that normally runs back to the transmission from the radiator and route it to the new cooler. You then run a line from the new cooler back...

  • Recommended Transmission Cooler on a 2001 Chevrolet Silverado 2500HD 8.1 L for Towing
  • I recommend going with the Flex-a-lite Cooler # FLX4118GMT that is a direct fit for your 2001 Chevrolet Silverado 2500. Even though the hose diameter may be less than your factory cooler the Flex-a-lite is definitely an upgrade. Just the size of the cooling surface alone makes this obvious. You can see a great comparison of the two in the attached video. The video also shows the installation process for you.

  • Do Transmission Coolers and Thermostats Come with Install Instructions
  • Our transmission coolers and thermostats do come with generic installation instructions but they are not-vehicle specific so for your 2013 Ford Edge they would not walk you step-by-step how to perform the install. The transmission cooler with fan part # FLX4190 that you referenced does need the thermostat control part # D18735 so turn it off and on at a preset temperature.

  • Which Lines Are Incoming And Return Line On Flex-a-lite Transmission Cooler For 2000 Chevrolet Tahoe
  • Most of the time the line that goes from the transmission to the top of the radiator is the inlet line. The lower line is the return line that goes back to the transmission. The best way to find the inlet line is to check when the vehicle engine is cold. Then start the engine for about 15 seconds. Shut the engine off and touch the lines. The warmer of the two lines is the inlet line to the radiator. The Flex-a-lite Translife Direct Fit Transmission Cooler, part # FLX4118GMT is a Class...

  • Electric Fan and Shroud Recommendation for Radiator that Measures 17 by 22 inches
  • The Flex a Lite Fan with Shroud part # FLX180 matches the dimensions of your radiator pretty close at 21-1/2" wide x 17-1/2" tall and can be used as a pusher fan so it would be your best option. It also can flow 3,300 CFM so your engine will be kept very cool.

  • Mounting Location for Flex-a-lite Transmission Cooler on Chevy Silverado
  • The ideal position for a transmission cooler like the Flex-a-lite Transmission Cooler # FLX4190 referenced in your question is between the vehicle's grille and AC condensore core, as this allows for the most airflow. With that being said, if you do not have the needed space available in this position, it can certainly be mounted in front of the radiator, behind the condenser. This tube-fin cooler and fan kit will provide additional cooling to protect your tranmission and improve its...

  • What is the Temperature Range for Flex-a-lite Temperature Sensor Item # FLX33011
  • The operating temperature for the Flex-a-lite Temperature Sensor Item # FLX33011 is adjustable. The range is 180 degrees to 240 degrees Fahrenheit. The rod that is on the top turns to adjust the temperature at which the fan will turn on. So if you have it set to the lowest setting it will kick the fan on at 180 degrees.

  • Compatibility of the Flex-a-Lite Translife Transmission Cooler on a 2005 Chevrolet Silverado
  • Most transmission coolers are universal in application and are intended to be an addition to and not a replacement for any OEM transmission cooler that may be installed on a 2005 Chevrolet Silverado w the Duramax Diesel engine. The With that said, Flex-a-Lite does have a recommendation for a cooler to fit your Silverado.

  • How Does Flex a Lite Cooler part # FLX4126 Mount to Vehicle with Included Hardware
  • The mounting hardware that comes with the Flex a Lite Cooler part # FLX4126 that you referenced is the long black rods that you see in the attached picture. What you do is slide those through the cooler and then also through the radiator of your vehicle and attach them with the anchors on the other side. The rods will push through the fins of the cooler without damaging them and provide a very solid attachment style.

  • Recommended Engine and Transmission Coolers for 2005 Dodge Dakota SLT V8
  • Towing will put an additional heat burden on both your engine cooling system and your transmission. A higher capacity radiator like Flex-a-lite # FLX50064 will certainly drop your engine temp when you're towing with your Dakota, but an easier and less-costly alternative is to simply add a powered fan like the Derale # D18217. Radiator upgrade are usually needed only for extreme applications like racing. This fan is a push or pull type so it can be mounted on the inside of your radiator...

  • Transmission Cooler Recommendations for a 2007 Chevy Silverado 3500 Classic w/Allison Transmission
  • Yes, you can use Flex-A-Lite transmission cooler # FLX4118GMT on your 2007 Chevy Silverado 3500 Classic with the 6.6 diesel and Allison transmission. If your Allison transmission is the A1000 model you could also use a cooler pan, # AFE46-70072. An aftermarket, supplemental cooler like either of the ones above, or both if you wanted, will definitely help keep the transmission fluid temperature down when towing.

  • Best Transmission Cooler for a 2012 Jeep Liberty Mounted Between the Condenser and Radiator
  • The best transmission cooler for your 2012 Jeep Liberty will be the largest one in the space you have available. If you are referring to position two as being between the condenser and the radiator, you will need at least 3/4" to do so. I recommend using a tube and fin cooler such as the Flex-a-lite Translife Transmission Cooler part # FLX4126 because this transmission cooler has one of the largest overall dimension in addition to the thinnest profile we offer. As long as you have 20" wide...

  • Transmission Cooler Recommendation for a 2016 Chevy Silverado 1500 with 5.3 Liter
  • The general rule is to keep the transmission fluid at or below 200 degrees Fahrenheit. When towing, especially in the mountains and in summer time, the transmission fluid temperature can increase much higher so adding a supplemental cooler is a good idea. A supplemental cooler can decrease the temperature significantly due to more airflow to the fluid and more capacity (fluid) in the system. The most popular cooler for your 2016 Chevy Silverado 1500 is # D13503. But if it were me...

  • Best Available Transmission Cooler For A 2012 GMC Yukon
  • It is certainly possible for you to add an additional transmission cooler to your factory OEM cooler. In most cases, the best cooler for your application will prove to be the largest available that will fit in the designated space. Fortunately, you have a good amount of room to mount an even larger cooler in front of the radiator behind the grill. As most factory transmission coolers are very basic, I recommend upgrading to our Flex-a-lite Translife Transmission Cooler w/ Guard part...

  • Could Flex-a-lite Mojave Vehicle Heater # FLX640 Fit a 2012 Polaris Ranger 500
  • The Flex-a-lite Mojave Vehicle Heater # FLX640 is designed for UTVs and smaller applications like what you have but it was not custom fit for your 2012 Polaris Ranger 500. It is possible for you to install this and have it work well but it would take a bit of creativity as it's not a direct fit. I attached a review video for this heater for you to check out as well.
