AC Lines O-rings or seal/washers

I'm replacing evap core, heater core, expansion valve, and condenser. There are some o-rings and seals or washers that go in various places. I don't know for sure where to put the seal or where to put an o ring. Anyone got any info on this?

 

Just do a google search “ Tacoma ac O ring kit for your yr. You can buy all of them at once. As you disconnect and replace parts. Just replace with one similar from the kit and oil them with pag oil.

 

Yeah, that's what I intended to do. I have them but I removed the old ones and forgot what went where.

 

just do an image search. Tacoma ac expansions valve O rings. Or look at a schematic from Toyota.
