evaporator core removal?
over a year ago, my a/c system started leaking. I have been adding a can as needed, but it is time to take care of it.
I went ahead and had my buddy order the complete system so I can replace everything. The condenser, accumulator, compressor and lines are all pretty straight forward.
My concerns are the evaporator coil. Has anyone ever replaced/removed it? Any information is greatly appreciated.

yeah, i lurk when i can, but work and a growing family has kept me busy. it's still good to stop in when i can.
i have replaced a few before in different f**ds, and they were all a major PITA. just hope someone here can give me some pointers.

hey, thanks Roland. That $20 manual i have was not as detailed. I like that they always say "reverse the removal procedure". It looked like it would come out from the engine side. Glad it does.
my dad is going to do the job for me as I do not have the time and he could use the extra cash.
Were there any diagrams? The old man likes pictures.

suspicions were confirmed, the evaporator was leaking. It was a very slow leak, but you could clearly see the spot where the leak was.
11 years on the original core- not bad I guess. It was about 1/2 plugged with lint and junk.
So now I have a perfectly good compressor, drier, condenser and lines sitting in the shop. Anyone need an a/c system???, lol.
