First, I want to say sorry for posting something someone has already posted but I couldnt find a post anywhere else about this topic. Ok this is the deal I now have all the parts to complete my a/c system (compressior, condisor, driyer, evaporator, ect.) So how excalty do i go about installing all this?

My brother told me that I need to remove the radiaidor to install the condisor and the compressior. Is this true? This sounds difficlut but I think I can do this myself. O and Im told that I will need a new belt as well because of the compressior. Dose anyone know the size that I need? while Im on the a/c topic my resistor (that controls the air flow on speeds of 1234 on the dash) only works on 4. How can I fix this issue? Thanks for any advice/guidence.
