You can do this, but you need to decide first if you want to learn how
and if you are planning to do it again. The tools to do the job right
will cost more than having it done, but you end up with the tools
which usually makes it worth it to me.
You should have a shop recover the 134a that is still in the system.
You can also just vent it, but that's not real legal or good for the
environment so at least pretend you had it recovered if you don't.
You will need new O-Rings at the connections for the new condenser
You need a new dryer.
You will loose oil in the old condenser and dryer. How much is a hard
guess. The FSM probably gives you a guesstimate. I usually just
drain the compressor, and flush the condenser (and I replace the
expansion device while I have it out). Then you can feel pretty safe
with putting back the factory fill amount.
After all that is done you have to use a Vacuum pump to pump down the
system and remove all the air. If you skip this step it doesn't cool
real well and the air and oil turn in to corrosive stew that eats
holes in everything else. Do a little research on how to use the
vacuum pump to pump down the system and check for leaks.
Now you are ready to fill it back up with refrigerant. Best to have a
good set of hoses so you can measure high and low pressure.
Educate yourself on how the systems work before you even think of
beginning. Once you understand how the system works it isn't all that
complicated. It can be damn aggravating though when you do all that
work and still have a leak and get to start all over again at step 1
