We had an accident (hit a deer on highway) out of town. A local mechanic removed the AC condenser and replaced the radiator so that we could drive back home. The AC condenser was not put back because the impact bar was bent and no enough place for the condenser. I've replaced the impact bar and got a new AC condenser. After checking online, I think there are three steps to replace the condenser.

Step 1. evacuate the system.
Step 2. put back the condenser.
Step 3. recharge the system. (I don't think I can do it myself. Will bring it to a mechanic shop.)

My questions are:
1. Since the condenser has been removed for about three weeks. Probabaly no need for step 1?
2. Since the condensor has been removed for a relatively long time (~ 3 weeks), do I need any special treatment for the system before/after putting back the condensor?
3. Should I worry about other parts of the AC? AC worked well before the accident and anything after the radiator looks untouched.

Thanks a lot!

 

1. Correct. Evacuating is removing the refrigerant - that's already been done
2. Make sure your new condensor comes with a new receiver drier - if not buy one (always use new orings)
3. If the system has been open a while - the vacuum pump should be left on longer than normal - to make sure any moisture in the system is boiled out.
The condensor/drier held a small amount of oil. Note the chart below with suggestions of the volume to put back in.

 

Thanks a lot!I didn't know about adding oil before reading your post. I checked online about when and how to add oil but got different opinions. Some say adding oil before putting components back. Others say adding oil during recharge. I'm confused and, to speak frankly, I still don't know how to add oil. Can I just install the condenser and connect the hose. Then bring the car to a mechanic shop and tell them to add oil for drier and condenser and recharge the system? Your instruction says "shall be filled in the system through the service valve", so I guess adding oil can be done after connecting the condenser to the A/C system? I appreciate your help!
