Again - thanks for all the info. This A/C job has really been a learning experience for me. Your picture of accumulator let know how they work.
Now I have to wait on parts and to get R134a evacuated. Will be next week sometime until I get all parts and can get-r-done!!

 

Something to keep in mind when dealing with the accumulator: The desiccant removes moisture from the refrigerant. It is similar to a sponge in that it will only hold so much moisture. When it reaches its capacity, the accumulator must be replaced. When the refrigerant system is open to the atmosphere, the desiccant is subjected to relative humidity, and it will absorb it very rapidly. The new accumulator comes with seals on the ports. When relative humidity is ~50% or higher, and the seals are removed, the desiccant will absorb the humidity and destroy the accumulator in under an hour. The new accumulator should be the last component that you install, and it should remain sealed until you are ready to add the oil and install it.

 

Yes sir was aware of that. Plan it to install it last right before I pull a vacuum. Another quick question - Was is the best way to flush evaporator? Should I use one of those flush cans you get at parts store? My concern is getting all the flush out.

Again many thanks for the help!!

 

Something like this will work fine. The can is pressurized so no shop air is necessary. The flush agent will evaporate quickly and leave no residue. The nozzle is rubber and has a trigger. Quick and easy. Save on Mastercool 91051 AC Flush Kit at ToolPan.com

 

Well the big brown truck just dropped off the last of the parts I ordered for this task. Now I have another question: When installing the new a/c hoses. how much do you tighten the hose connections. Don't want to over tighten on the o-rings or damage any of the aluminum fittings. To late to start today but am retired so can start first thing in the morning. Radiator to come out first to reach the condenser connections. Did end up buying a vacuum pump as no one wanted to rent one and could not find a friend with one. Wish me luck

 

Manifold to compressor bolt: 24 foot pounds
High pressure line to condenser: 18 foot pounds
Low side line to accumulator: 30 foot pounds


The compressor must lay flat against the bracket, no rocking in any direction. If it does not lay flat, compressor life will be shortened. The compressor mounting bolts must be tightened in an "X" pattern to 37 foot pounds.

 

Thanks Captain - Will keep you informed!!

 

OK need some more help. Took me half the day to get the radiator drain plug opened to drain the radiator. Now can not get oil cooler lines and bottom transmission cooler lines out of the radiator. Removed the clips with no problem but they just won't pull out. Any suggestions? The top transmission cooler line popped right out, rest won't budge.

 

If it ain't one thing, it's 6 others Usually they just pull, or fall, out. Probably have to turn them back and forth to break the rust loose. Clips & rust is all that holds them in there

 

Went back out after I posted last and after quite awhile of wiggling and pulling they finally all pulled free and the radiator is out. Found out while taking it all apart that the lower fan shroud was in bad shape and only two of the screws were in it. So ordered one of those and should be here Thursday due to my Amazon prime account.
Done for today - due to humidity and age calling it a day. Ready to dig in on the A/C tomorrow - can't wait.
