I needed a new charge anyway. I was planning on just getting a new compressor draining the oil out. And hooking it back up to the system. And have a shop flush the condensor and evap and then evac the system. fill the compressor up with oil and refill with r12. And hope this works.
Or can i not fill the compressor up wuth oil once i evacuate it ? Not sure how that works.
But im having a hard time even finding a shop wanting to even do a flush and evac on a 32 year old Jeep.
Its like everyone is just a bunch of panzies how is it any diff then doing thst on a 15 year old car ?? Its iritating.
To answer your question. Valves ? You mean the pin needle like valve on the ends of the hoses ? Yes i have two of those. I connect the r12 can. Then i have to turn the valve on the hose itself to let the r12 in. So youre saying since i have that all i need to do is close both of them. Then disconnect the lines from the compressor ? Then drain and flush the new compressor. Fill it up with oil and turn the pump to get it all in there by hand. Then hook it up to the lines and reopen the lines ?
How would installing the low side and cracking it open purge the pump. If the high side on the pump is disconnected ? Wouldnt that still be an openeing for air ? Or do i gatta connect the high side quickly while the low side is purging the pump ?
You sure these valves arent just to open and close the external low and high ports for when you hook something up to it or do they actually close the hose off as well ? Because ehen i fill the system eith r12 i turn the top valve to open the port. And then close it and remive the r12 can. I didnt think these also block the hose off to remove it from the compressor ? Because once i close the valve and take the r12 can off. The system free flows.. Soo how do i close the hose with valve ?? What does front seat the valve mean ? Does that mean turn it all the way clockwise ? Which i assume pushes the valve all the way in to block the port in the hose itself ?
Here is what mine looks like
