We didn't add any oil this time. We are going to add some oil and dye when we refill it again because the refrigerant leaked out again. These AC systems are a pain when you are chasing leaks!
I figured it had something to do with the conversion, but wasn't sure why it was on the drier. I'm just glad it is cold now, but not as relieved as my son. He was sweating for a couple weeks while we tried to figure out the problem.
We don't have one, so we didn't. Another tool to buy. Didn't matter though because there is a leak somewhere and it stopped working again. More work to do when summer comes around again.
@@C3KPaddock you can rent it from autozone and get your money back when you return it. You would of figured out that you had a leak if you would of properly done a vacuum . Also since you didn’t you might ruin the compressor and have to replace it too along with the new drier again .
@@chillyE30 Good to know. I wasn't aware that was something you could rent from there. We haven't been running the A/C since it leaked down. Thank you for the tip on the vacuum.
@@C3KPaddock any moisture in the system can corrode and kill the compressor as well as clogging up the system. putting it under vacuum for an hour or so makes all of the moisture in the system evaporate and get evacuated. the drier is there to continually suck up any incidental moisture that could get into the system to protect it, it can only soak up so much so it's kind of a sacrificial part, you'll need to replace it again if you try to get the a/c working again for this summer. it's worth it to get a set of a/c gauges while you're doing this (either renting or you can get them + a vacuum pump from harbor freight for like $150) so you can get a better idea of what's not working in the system. also the hoses in pre-88 E30s are older style (not future-proofed for R134a) so you're going to continually have at least a little leakage
@@Vanya2893 I broke down and took it to a shop a few days after we filmed the video to get the A/C vacuumed and filled properly. It worked great for like a week and then gradually got worse over the next couple weeks until it barely cooled again. I think there is a fitting on the dryer that is leaking. The shop said they did a leak test and it was all good, but when I took it back they said they were going to charge me again to service it. Frustrating!!! I hooked up a gauge and the pressure was way down. Going to have to get the equipment and do it myself I guess.

Where did you get the dryer? I need the same one and can't find anywhere. Please let me know. Thanks Dave
Thanks so much , did the exact same and great results. Did you add any oil to the system? Or just refrigerant ?

@@C3KPaddock Thanks for the reply. No leaks yet for me, fingers crossed
That fitting is because its been adapted from R12 to 134A.

Did you vacuum the system ?? You opened it up it needs a vacuum .
