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.
