  Q: How to Service and Repair an Intercooler on Dodge Ram 2500?

  A:

  You should remove the battery's negative cables before starting to service or repair the charge air cooler. If the A/C is in the vehicle, let out the refrigerant, remove the A/C Condenser and next remove the transmission auxiliary cooler. After that, cut the electrical connection to the boost tubes and unscrew the bolts on the charge air cooler, lifting it up and away. Keep caustic cleaners away from the air cooler and if you can't clean inside, replace the entire unit. If your charge air cooler fails or gets dirty, set it with its tubes parallel to its axis, flush it and shake it from inside and tap the outside tanks with a rubber mallet to clear any objects inside. Wash in running water until everything is clean, then rinse with soapy water and thoroughly with clean water and dry the parts with compressed air. Check the charge air cooler carefully for damage, especially on the tubes, fins and welds; if damage is found, you should replace it. Use Charge Air Cooler Tester Kit # 3824556 with the supplied instructions to pressure test the charge air cooler. While doing the installation, set the charge air cooler in place, replace and tighten its bolts to 2 Nm (17 in. lbs.) and after that, attach the air intake system tubes and close their clamps to 11 Nm (95 in. lbs.). If you have removed the transmission auxiliary cooler and A/C condenser, put them back in their positions, charge the A/C if necessary, attach the battery negative cables and check for leaks when you start the boost system.
