Esky update time. Didn’t get a chance to do this yesterday.
So we know the compressor clutch took a dump and I found metal shavings in orifice tube.
So I had to replace condenser along with the other components because you can’t flush a ‘96+ condenser and get it clean. You also can’t flush thru an expansion valve either so I bought a new one. Front uses the orifice and the rear ac uses an expansion.
This past week has been hot as hell and 600% humidity so I didn’t get started on this until Saturday after work. It’s still hot and humid in garage.
With my favorite beverage condensation on the work bench I started removing the condenser first to make sure I have the correct unit.
Appears to be the correct unit so onward we go. I didn’t want to make a mess flushing the lines so I decided it would be easier to just remove every line and hose and flush off vehicle.
No, I didn’t remove rear lines, I’m running low on my energy pods. Here you can see the lines that go to the rear, the one goes to evap for front, there’s another that’s just lower than that one with the stud sticking out for the high side. Figured I can do my flushing from here and hook up hose to the back to catch the flush. Front evap was easy to do so I just left that hard line attached and flushed them as a unit.
I had to clean the cooling stacks in radiator because it was filthy. You can see in picture above how dirty it was. I guess i didn’t get a pic after I blew it from the engine side forward, sprayed it down with condenser cleaner, followed my water and then blew it again. But here’s new condenser in place.
I’m OCD when it comes to closed loop systems. Wether it be ac, hydraulics or air, I don’t leave things open to exposure to contaminants or moisture. I like to use foam ear plugs but I didn’t have any left so I just used vacuum caps where I could fit them and anything too big I just use latex glove and zip tie.
Now lines are clean, condenser is in and everything is sealed up, time to pull the compressor.
You can see how bad this clutch got smoked.
Time for my refurbished bracket and new idler to go in as well.
By the time I got compressor and bracket mounted, and finished my beverage that was getting closer to boiling by the minute, I figured the lines had enough dry time so I put the entire front system back together. Just the rear lines weren’t connected but they were sealed off to keep from saturating the desiccant in the accumulator.
I went to the rear to tackle the expansion valve. But before I get into that I want to share how much of a be-otch the rear lines were to disconnect from expansion.
I soaked them with PB Blaster, used heat gun on high setting about 50 times, tapped chisels between mounting flange and expansion, small pry bars, more heat, more PB, stepped up my game to Kroil penetrating oil, more prying, more heat, tapping on it with a hammer to jar it, more beverages, more swearing, took my last energy pod and finally got it off!!
I think I spent 2-1/2 hrs on getting the lines off trying not to crack the rear evap lines, break the rear line itself or the mounting block.
Then the little 6mm mounting screws that held the expansion on were a ***** to remove. Takes a 3mm allen wrench and I was desperately trying to not round it out. If I would have had to drill the screws I most likely would have had to take the rear evap out because they were seized in the expansion block itself and there’s no way to pry it off from underneath. But I kept working at it for about 4 beers time but got em.
Flushed the rear evap, let it dry for about 45 minutes then installed new expansion using a generous amount of anti-seize on mounting screws and also on the stud that holds the line mounting block on.
I attached my ac gauges, hooked up service port on gauges to vacuum pump and ran pump for 45 minutes. Closed the gauge valves, removed the pump and held vacuum on ac system for an hour. Vacuum stayed steady at 28”hg so I’m confident there are no leaks. While system is under vacuum, I used the service port on gauges to sucked 8oz of pag oil into system. Compressor already had 3oz in it and system calls for 11oz total.
Once that was done I charged the system with 26oz of Freon, that’s all I had. Gotta get more today and top it off. Need 40oz total.
Oh, and I always turn the compressor over by hand for about 2 minutes to make sure it’s not gonna hydro lock from the oil. Just a good practice that I always do.
Caddy has air, system is clean and new so hopefully won’t have to mess with it for a while.
