  The male end of the Derale Radiator Adapter part # D13018 that you referenced does thread into the outlet side of the factory cooler in your radiator.

• Should a Transmission Cooler Go After the Factory Cooler on a 2005 Chevy Silverado 2500HD

You may also need an additional fitting to avoid cutting and flaring lines. The correct fitting depends on the engine in your truck. If you have a 4.3 liter or 8.1 liter, use fitting # D13018.

• Recommendation for Cooling the Coolant and Transmission Fluid Temperature on a 2008 Chevy Avalanche
  For the radiator coolant temperature, I recommend adding a supplemental fan or fans depending on how much space you have under the hood. There is no limit to the amount of fans you can have. A pusher fan, mounted in front of the radiator pushing air through it, would be the most efficient (provided that the factory fan is mounted on the same side and pushes air through in the same direction). A puller fan would be used on the other side of the radiator to pull air through. The largest electric...
