Refrigerant Replacement

So I recall a lot of oil from the compressor falling out when I did the engine swap back in the winter initially. I took the compressor out the other day and drained it completely. Would a good assumption be that 3/4 of the nd-11 oil is held in the compressor?

 

I guess this answers the Q if the gen 2 compressor is the same? https://priuschat.com/attachments/picture-3-jpg.10485/

 

Basically I can assume the amount based on what I visually caught when oil came out and what I drained out later it looked like it had at least 1.5 oz to 2 oz. But I don’t know because I didn’t catch the oil when it drained out the first time. The manual alludes to the total amount the system has and says subtract the old oil compressor amount from this new amount. Kind of difficult to guess if you didn’t measure the first spill amount.

I bet a professional would probably flush out the system somehow or just replace the compressor with a new one that comes filled with oil already.

 

can’t afford a professional. Research time.

 

Got a new bolt and o ring. Installed them to 7lbs torque. Pulled a vacuum to 29 microns for an hour. Let it sit for an hour. No change on the gauge. I'm going to pull a vacuum again for another few hours tomorrow morning before trying to add oil and change the desiccant. Then I guess it's charge the system time.

Today's high in the nation's capital is 97.

 

Crucial @lech auto air conditionin video I was looking for. @Paladain55 mentioned the Schrader valve needs to removed from the high side before connecting the injector.

Something that's not clear yet is purging the charge hose at the gauge. There was a video of dude just pressing on the Schrader valve until refrigerant came out. That seemed like the wrong illegal thing to do, any other suggestions?

 

Receiver drier wasn't that bad

 

Done. Getting Cold air now. Thanks to everyone who assisted.


1 ounce of poe oil was added on the high side(liberal guess) with an injector while pulling a vacuum. Continued to pull a vacuum, purged the hose up to the gauge and I filled based on weight. The ac 1423 code I was getting is gone now. Gonna go back to the manual to check the gauge reading, I think I was around 99. Hope that isn't bad.

 

Someone please explain why the psi is so high but I'm not getting any fault codes. I read another thread that quoted the psi a lot lower. I would think there'd be a fault code if the expansion valve froze due to bad charging because of any inaccurate vacuum and if the psi is higher than usual. I understand it's variable rate but don't get the readings completely.

Air is nice and cold but for how long? Paranoia

 

Rpm around 4000-5000 at low fan setting.

 

Only reference I see is 0-10000 rpm with 6000 being the max

 

After running it for a few minutes it climbed to 150+ psi.
