Expert Answers about Derale

  • Bypassing Factory Transmission Cooler on a 2006 Nissan Pathfinder
  • It is possible to install a transmission cooler and bypass the factory transmission cooler on your 2006 Nissan Pathfinder. This is not recommended by manufacturers, but it is possible. You will want to get the largest transmission cooler that will fit your vehicle. I do not know the area that you have available to install a transmission cooler, but if it will fit, I would recommend the Derale Series 8000 Plate-Fin Transmission Cooler Kit, part # D13504. The overall dimensions for this cooler...

  • Comparison of Plate and Fin Style Transmission Coolers and Tube and Fin Style Transmission Coolers
  • The difference between the plate and fin style, # D13504, and the tube and fin style cooler, # D12904, is that the plate and fin models can cool better than the tube and fin models. You will notice that plate and fin coolers with the same rating as tube and fin coolers are smaller in size. Basically, the plate and fin cooler provides more surface area to extract heat from the transmission oil and also has internal turbulator technology to help the oil to cool faster and prevent pressure...

  • What is the Towing Capacity of a 2004 GMC Sierra 1500 4x4 with 5.3 Liter Motor
  • For a 2004 GMC Sierra 1500 4x4 with the 5.3 liter the towing capacity will be one of the following depending on how your truck is configured: Regular Cab, Long Bed 3.73 rear end, 8,000 4.10 rear end, 9,000 Crew Cab, Long Bed 3.73 rear end, 7,500 pounds 4.10 rear end, 8,500 pounds Extended Cab, Long Bed 3.73 rear end, 7,600 pounds 4.10 rear end, 8,600 pounds Regular Cab, Short Bed 3.73 rear end, 8,200 pounds 4.10 rear end, 9,200 pounds Extended Cab, Short Bed 3.73...

  • Tow Capacity of 4x4 2007 Chevy Silverado Classic with 5.3L and Transmission Cooler Recommendation
  • You will want to first consult your vehicle owners manual but based on my research your truck has a standard towing capacity of 7,500 pounds and max towing capacity of 10,500 pounds. The max is usually either with the truck properly equipped or when using weight distribution. Your owners manual should be able to shed some light on this. Even with the truck properly equipped, and/or using weight distribution you will still be near the maximum of the truck. If a more capable truck is...

  • What do the Class Ratings Mean on the Transmission Cooler Pages
  • You can install a stack cooler in your vehicle. The Class ratings are there as a reference point to a hitch Class. For example if someone has a Class III hitch they can look at coolers, see a Class III and say, hey, I have a Class III hitch so this Class III cooler will be good for me. We tried to just make the choosing process easier by assigning a Class. Transmission coolers are not actually vehicle specific so you can use any one that will fit in the space you have available, included...

  • Transmission Cooler Recommendation for a 2007 Chevy Silverado 4x4 with Tow Package and 5.3 Liter
  • The ideal operating temperature for the transmission and fluid is between 160 and 200 degrees Fahrenheit. Transmission fluid cannot be overcooled, so adding an aftermarket cooler would be a good idea as factory coolers can be inadequate for towing applications. The Derale Transmission Cooler, # D13502, is one of the recommended coolers for the 2007 Chevy Silverado with the 5.3 liter engine. Since you are towing upwards of 9,000 pounds, I would recommend a higher capacity cooler like...

  • Transmission and Oil Cooler Recommendations for 2008 Dodge Caliber
  • If your CVT transmission has lines that run from the transmission to the radiator (some do, some do not), you can install a transmission cooler. 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...

  • Recommendation For Transmission Cooler on 2008 Chevrolet Silverado 1500 LS With 4.8 Liter V8
  • Ideally you want to keep the temperature of the transmission fluid in the 160 to 200 degree range. You cannot cool transmission fluid too much. Transmission coolers are universal fit items so you will want to measure the space you have in front of your air conditioning condenser or your radiator to see what size cooler will fit your 2008 Chevrolet Silverado 1500. Installing an additional transmission cooler in-line with the current transmission cooler would help in cooling the transmission...

  • Which Transmission Cooler is Recommended for a Nissan Frontier with 6,500 Pound Towing Capacity
  • The best way to decide which class cooler you need is to take a look at what you will be towing and where. If you will be towing a light load, less than 2,000 pounds, in flat driving conditions, your vehicle will do fine with a Class I. If you will be towing 6,000 pound load through some hills, I would use the Class III cooler. I prefer the 8000 and 9000 series. They are built a little heavier and are more resilient. The 7000 series are built a little lighter and can be damaged more...

  • What is Correct Placement of Derale Dual-Pass Heat Sink Transmission Cooler # D13265
  • Maximum air flow will increase the heat exchange performance of any oil or transmission fluid cooler. This is true for flat plate-fin and tube-fin type coolers that typically mount in front of the air conditioning condenser as well as for heat-sink-type coolers intended for mounting on the frame rail. If mounted in a location that does not provide maximum air flow the cooler will still help to reduce the fluid temperature to some extent but it will not function at its best. If you prefer...

  • How to Determine Which Transmission Line is the Return Line for Installing a Transmission Cooler
  • The method we use to determine the correct line to install a transmission cooler on is pretty simple. You want to install the cooler on the return line. To determine which line is the return line you will want to start with your truck totally cooled off. Start the truck and put it in drive, apply the brakes firmly and then apply the accelerator slightly so that the rpms climb. Put the truck back in park and shut it off. Now go out and feel the two lines leaving the radiator. The cooler...

  • Installing Derale Transmission Cooler to Replace OEM Cooler on 2007 Nissan Frontier SE
  • The Derale transmission coolers we sell are designed more as a supplemental cooler that is meant to augment the factory transmission cooler portion of the radiator, not replace it entirely. If you are experiencing the common problem with the radiator leaking causing the engine coolant contaminating the transmission fluid, your best bet really would be to have the original radiator replaced. I did a Google search using the keywords Nissan Radiator Problem and found that Nissan has extended...

  • Transmission Cooler Recommendations for a 2005 Chevrolet Silverado 2500 HD 6.0L
  • When it comes to installing an aftermarket transmission cooler you will want to choose the largest and highest rated transmission cooler that will fit on your 2005 Chevrolet Silverado 2500 HD 6.0L because transmission fluid cannot be over cooled. Aftermarket transmission coolers are supplemental coolers and are designed to be install in-line with your factory transmission coolers return line.

  • Transmission Cooler Recommendation for a 2013 Chevy Silverado 1500
  • All vehicles with an automatic transmission have a factory transmission cooler. Normally it is located inside the radiator but it can also be outside of the radiator. Trucks that have a tow package often have a larger cooler that is outside of the radiator. Regardless of where your factory cooler is located, you can still add a supplemental cooler because transmission fluid cannot be over cooled. You are correct about towing in warmer weather and in the mountains. It will increase the...

  • Installing Transmission Cooler on 2009 Chevy Silverado Without Cutting Transmission Lines
  • You can indeed install a transmission cooler without tapping into any lines. The # D13504 cooler you referenced would be an excellent choice. You would also use the # D13035 radiator fitting. The most efficient location to mount the cooler itself is directly behind the grille, in front of the radiator and A/C condenser. The installation would involve simply removing the existing transmission return line from its connection at the radiator. The # D13035 fitting would install in its place....

  • Transmission Cooler Recommendation for a 2011 Chevy Silverado with 5.3 Liter Engine
  • The optimum temperature for transmission fluid is between 160 and 200 degrees Fahrenheit (70 to 93 degrees Celsius) so at 240 (116 Celsius) you were definitely above that range. When towing up a high at low speeds using a low gear or towing mode, if available, would be the correct way to go about towing the trailer. I would recommend adding a transmission cooler to your 2010 Chevy Silverado. I would use a class III or higher cooler rated for at least 6,000 pounds. You can use # D13503...

  • Transmission Cooler Recommendations for a 2002 F-350 with the 7.3L Diesel
  • Transmission fluid should run below 200 degrees Fahrenheit. At 240 degrees you definitely need to make some sort of change to reduce the temperature. I would first recommend having the transmission checked by a qualified automotive technician to be sure it is performing properly. This will assure you that no damage has been caused to the transmission and you will not be stranded. Installing a transmission cooler will not reverse any damage that may have already been caused. If you find...

  • Oil and Transmission Coolers for 1993 Dodge with 250 Cummins Diesel Operated in Desert Climate
  • Since oil and transmission coolers come in a range of sizes and types, and can mount in any location that will provide air flow (or in the case of fan-powered units enough space for convenient mounting) you can install both a secondary transmission cooler and a fan-powered oil cooler. I recommend using a secondary transmission cooler in addition to the OEM unit rather than bypassing it. The secondary cooler will take the already-cooled transmission fluid from the radiator and further...

  • Why Would a Vehicle Need a Power Steering Cooler
  • Any time a vehicle is not moving or if there is extra weight in the vehicle or because the vehicle is towing it makes it harder for the power steering components to do their job (because of the extra weight or lack of motion). This extra stress produces heat which can damage the power steering pump and break down its fluid. Some vehicles like those made by Toyota require a power steering cooler when towing. Consult the owners manual to confirm for any vehicle. Power steering units don't...

Transmission coolers are universal fit items so you will want to measure the space you have in front of your air conditioning condenser or your radiator to see what size cooler will fit your 2010 Chevrolet Silverado 1500.

  • Replacement for OEM Transmission Cooler in 2006 Ford Crown Victoria Police Cruiser
  • The aftermarket oil and transmission coolers we offer are intended to supplement OEM coolers that are built into vehicle radiators. These supplementary coolers are typically employed for towing applications. Products like the Derale Series 8000 Plate-Fin Cooler that you referenced, part # D13503, and others that we offer are not intended as replacements for original equipment components. A police-spec vehicle usually has heavy-duty components in the braking, transmission, electrical...

  • Transmission Cooler Recommendations for a 1998 Chevrolet Silverado 4X4 5.7L
  • To determine what kind of transmission cooler you will need depends on how much weight you will be towing and where you will be towing. Also, you will want to check how much room you have in front of the radiator to be able to install the transmission cooler. If you will be towing a light load, less than 2000lbs, in flat driving conditions, your 1998 Chevrolet Silverado 4x4 5.7L will do fine with a class I rated cooler. If you will be towing more than a 2000lb load through some hills,...

  • Transmission Cooler Recommendation for a 2004 Chevy Silverado 2500HD with 6.0 Towing a 5th Wheel
  • Given the weight of your trailer and the fact that you tow uphill I recommend going with the largest cooler or most efficient that will fit in the available space you have in the engine compartment of your 2004 Silverado. A stacked plate cooler is going to be the most efficient. For a stacked plate that is very efficient and rated as a Class V I recommend # D13403. It measures 13 inches wide, 7-5/16 inches tall, and 2 inches deep. I also recommend fitting # D13035 so you do not have...

  • Transmission Cooler Recommendation for a 2009 Chevy Silverado 1500 Crew Cab with 4.8 Liter Engine
  • The ideal operating temperature for transmission fluid is between 160 to 200 degrees. Your 2009 Chevy Silverado does have a factory transmission cooler, but factory coolers are often inadequate for towing. Since your fluid is reaching 250 degrees, you would benefit greatly from a transmission cooler. For your 2009 Chevy Silverado 1500 with the 4.8 liter engine, I recommend the Derale Transmission Cooler, # D13503. This is a class III cooler rated for up to 6,000 pounds gross trailer...

  • Is a Radiator Fan Supposed to Spin Freely By Hand When the Engine is Off and Not Running
  • 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...

  • Transmission Cooler Recommend For a 2002 Ford F-250 XLT Super Duty 6.8L V10
  • When installing a transmission cooler, it is always a good idea to install the largest cooler that will fit in the space available on your truck. Transmission fluid cannot be over-cooled, however, if you live in a typically cold climate, it is a good idea to let your vehicle run for 10 minutes before taking off. For your 2002 Ford F-250 XLT Super Duty, going with the Derale Series 8000 Plate-Fin Cooler, # D13504, that you referenced would my recommendation. It is recommended to install...

  • Recommendations for Cooling a C4 Transmission in a 1966 Ford Bronco Rock Crawler
  • It sounds to me like you will definitely want to upgrade your transmission cooler. Since you will not have a cooler that is being cooled by the fluid running through the radiator, I agree that you will need to upgrade or add a cooler to your system. Heat Sink Coolers like the Dual-Pass Heat Sink Transmission Cooler, item # D13266, that you referenced are not nearly as efficient as a plate and fin cooler or a cooler with an electric fan added. If you are running an electric fan with...

  • Supplementary Transmission Cooler for 2004 Silverado 1500 LT That Has a Factory External Cooler
  • It is possible that your 2004 Silverado 1500 has an external transmission cooler from the factory; it is also possible that the previous owner installed an aftermarket unit. Some auto makers place a tranny cooler inside the radiator. You can confirm that the unit you are seeing is indeed a stand-alone tranny cooler by following its lines back to the transmission case and you can certainly add on a second cooler for your transmission if you wish and this would indeed be a good idea for your...

  • Does a 2007 Toyota RAV4 Towing a 2000 lb Boat Need a Transmission Cooler
  • The Curt Class III receiver, part # 13509 is highly rated and would be a great choice for your Rav4. According to my research, the 2007 V6 is rated for 3500 lbs of towing when properly equipped. I would recommend checking your owners manual to confirm your towing capacity. To complete your towing system, you might need the following: Trailer wiring harness with 4-pole trailer connector # 118412 Ball mount, # 2923 2 inch trailer ball, # 19247 1-7/8 trailer ball, # 19260 A...

  • Why are Transmission Coolers Installed on the Fluid Return Line After the Radiator Mounted Cooler
  • The biggest reason that transmission cooler manufacturers and vehicle manufacturers want transmission coolers installed after the factory cooler rather than before it is because the transmission cooler in the radiator is surrounded by the coolant in the radiator. The transmission fluid leaving the radiator mounted cooler can be cooled further by the aftermarket transmission cooler. Installation before the OEM radiator mounted transmission fluid cooler would negate most or all of the...
