So I recently did the plenum repair with the kegger mod. Before this repair I would only occasionally add refrigerant to the trucks A/C. When I finished the repair I turned on the trucks A/C to check it and found that it was low. So I add the required amount of refrigerant. One to two days later I find the pressure is low again. I went ahead and added the dye to the system and charged the system again. The next day the system is low again but I can not find any location where the refrigerant and dye are leaking out. So I charged the system again. This time when the system went low after checking for the leak I see what looks to be droplets of engine coolant on both of the A/C pressure lines. I recently converted the truck over to electric cooling fans and I do not have the coolant recovery tank installed yet. So I would not be surprised to see droplets of engine coolant on the lines. When I checked the drops for the fluorescent dye they they glow under the UV light. Now the rubber looks fine on these pressure lines but the refrigerant seems to be leaking out of pin holes in the rubber pressure lines.

All I did when I did the plenum repair was unbolt the compressor and lay it over to the side and out of my way. I guess flexing the line the other way may have caused this.

I installed new lines and recharged the system so I should know by Saturday if that was the fix but from what I saw I am fairly confident that it was.

 

Hhhmm..... not sure that is gonna fix it..... I wouldn't be surprised if the evap core wasn't where the leak was. These trucks are pretty notorious for that.....

 

So far so good. I put the gauges on it this morning and drove it allot today. all seems good. Time will tell.

 

Looks like that did the trick. Does not seem to be leaking now.
