On most cars it will engage without refrigerant.

Re: who has put an ac belt on
 

Most cars have a low pressure switch in the system that doesn't allow the clutch to engage below a certain pressure on the low side.

Re: who has put an ac belt on
 

Just like everyone else has said, when the low pressure switch see's that there isnt enough pressure in the system it will not kick the compressor on. You need to take it somewhere and have it dye tested to find out where your leak is at in the system and then have that fixed and then recharge the system with 134a. Or if you just want some ac for the summer just charge it up and hope its a small enough leak to last until its cooler out. BTW..you dont have to support the engine at all if you pull that lower mount off, the others should support it well enough.
