W124 A/C r12 refill

[300e92]

hello guys, im new to this, i own a 1992 mercedes benz 300e base model, 3 months ago i was replacing the auxiliary fans and i disconnect the pressure lines to the condenser, i re connect the lines almost instantly, before that a/c was working smooth, but now the a/c is not cold enough anymore, i am not a certified tech, but i would like to recharge the system myself, there is a label that states r12 in the engine bay, so,
1-can i just recharge it or do i have to evacuate the whole system?
2-can i just re-fill the system with the kits on ebay?
3-do you guys know how to do this?
thanks for your help guys.

Based on what you said about yourself, I rec that you save up a few hundred dollars, and find a pro who works with r12. Have them replace the receiver/dryer & pressure switch, evac the system, recharge with r12, and be done with it in a few hours.

Or, use the "Search" function above to find and then read the many tens of threads here that have already answered your questions

You should evac the whole system. You should not just add r12.

I did a search and only two threads came up. This is the only relevant thread of the two.

Why are you set on r12? Just curious.....

Sorry, I missed your post.

I don't want to do a conversion. I don't want to spend the time or the money. I'm just trying to get through the summer. Only 6 weeks to go. Hopefully by next summer, I'll be driving one of my R134a cars and it won't be an issue.
