Default 80 A/c ?

On the 80 A/C system..which is the "low" side...the fitting by the compressor or the one back by the big aluminum thing (condensor?) close to the fire wall and heater core box?

Yep - you guessed it - I don't know anything about A/C

Been told that the big silver thing is an "accumulator"?

They both are. The high side is by the right wheel-well and is attached to the siteglass.

Please confirm that I have this right. To add refrigerent, I'll add at the line fitting tap that is coming from the evaporator (low side) to the compressor? The line into the evaporator, leaving the compressor is the high side?

Add freon to the ports connected to the big lines. The small lines are high pressure.

The one on the compressor is the easiest to get to.

DO NOT hook up the filler hose to the high side.

The can of refrigerant will turn into a grenade.

When in doubt, ask more questions...

The large line is the low-pressure side. The fitting on the low-pressure line is larger than the fitting on the high-pressure side.

Just in case.... since you said you don't know much about AC are you sure you have the right TYPE of refridgerant? The 80 does not use the 134A that you may very well have bought at AutoZone without converting the system....

I had some R12. You guys made it simple by pointing out the big line is low pressure and small is high...charged and blowing cold.
