hi I have a 94 zj 6cyl 4.0
I just changed my heater core and in the process I had to disconnect the a/c lines going to the a/c evap in the firewall.
I finish the job but i had to get some green 0-rings to replace the ones on the a/c lines my question is since i dont have enough money for the
PAG oil is there a alternative i can use to oil the o-rings with?
And just to be sure to re-connect the lines do i need a tool like the one i use to dis-connect them?

Ok I cant find the nylon blue but through reading online i see alot of machanics use a light smear of mineral oil or dielectric grease
to lube the o-rings for the lines....

question.
Can i run my defrost without getting the compressor oiled or recharged

Unplug the wire / connector from the compressor clutch coil .

Defrost will probably not work as well , if the A/C is not running , performing dehumidification .

God bless
