2003-2009 5.9/6.7 3rd gen Cummins A/C repairs. Compressor, orfice tube, dryer and condenser

2003-2009 3rd gen Cummins. The 6.7 Cummins may use some different parts but I’m pretty positive on the 3rd gen it’s basically the same dodge made some changes when the 4th gen came out. Compressor clutch was stuck engaged and stopped creating pressure after the compressor discharged out of the relief valve. I originally tried to just recharge it after I replaced the fan clutch which can cause clutch and compressor failure. I pulled the trigger on a complete ac system replacement because it’s cheaper than replacing the compressor twice!
Make sure to have your A/C system properly evacuated a professional repair shop should evacuate and recharge your system for relatively cheap before and after your repairs

Thank you for doing a in depth and detailed explanation of the AC process !

[@TheRancher03]

The toughest part is quick connects if they have been on there for a long time exposed to heat and dust and the o-rings have dried hardened. Putting PAG oil on the plastic or metal removal tool and pressing in a few times while twisting makes it a lot easier.

Awesome and informative video. Glad to see people making in-depth guides and showing how to do it, rather than say it and expect people to know. This will help a ton of people. Keep up the great content! Subbed.

Thank you for the video! I have a 2003 5 speed same color/engine and AC problem!!! My compressor when out today. After watching this vid I feel confident I can do the same thing here.

[@korn111685]

Thanks. I’m about to do this job on an 06, my personal truck. I just learned my AC compressor is locked up tight. I’ll try the couch for the evap. Thanks.

Great video.

[@danielalvarezzayas8065]

I’m having a hard time installing the new one I can’t figure out how to open the spring when trying to insert the new line

[@Neverquit275]

Great job thanks for the detail that really helped. I’m replacing everything fire wall forward new. What is the flush solvent & where does some pick it up. What were you blowing the lines out with after you ran the flush solvent, just air until it’s dry inside?

[@josiefitzsimmons148]

Great video! Super informative.

[@ryanfavors387]

What amount of pag oil did you have to add? My compressor comes with a factory load of oil, but how much needs to be added to compensate for the system?

[@eliasfaithjoseph1]

What parts did you use after market or oem

[@jasongriffin1127]

How did this kit hold up?

[@coricastillo3489]

[@esteban6455]

[@Golden_6.7]

[@guacamoleweiner69]

The discharge hose/condensor inlet hose

[@crunchytacosupreme9371]

How much would a job like this be? Just for the labor.

[@ryanallen234]

[@davepullen4628]
