Hey Guys,

Alright I took my compressor off and opened the ac system. Now its time to get it back together. Everything is back on and I am ready to vacuum the system out so I can recharge it.
Except I dont know how. can you guys give me the "how to" up to jumping the wires and putting in 134A. It holds 22oz corect?

 

Suggest you download the RAVE so you can go by the book. Also suggest a new drier since you had system open, they are cheap.

 

What were you doing that you had to take the compressor off and disconnect the hoses? You don't even need to disconnect the hoses from the compressor when replacing the engine. It just unbolts from the intake and you can secure it to the left inner fender, hoses still attached.

x2 on replacing the drier. The desiccant in the drier is now shot as it has absorbed moisture from the atmosphere.

 

Why would you open the system, you now have moisture and junk in the system. You will need to have it pumped down, leak tested then add a/c oil and freon per the manual.

 

a/c is the ONE thing I dont mess with. Having had a bad compressor on a 97 4runner, I got a used compressor threw it on and paid 70$ for a shop to vac and charge it, blew SUPER cold

 

Vacume down to negative 5 at least. Insert the PAX oil first and then the Freon. Make sure you know how much PAX oil to use. Too little and you will burn up the compressor. If you removed the compressor you should be installing a new expansion valve and dryer. Charge the system and check the gages for proper pressure low/high. OH AND BY THE WAY, IT IS ILLEGAL TO EXPELL FREON INTO THE ATMOSPHERE. Have you heard about the ozone problem?

 

Know what type of compressor you have, look for the capacity spec, add the correct amount of oil. If you still have the old one, you can measure the drained oil from it, not unless the old one blew a hole. If it was a blow out, start fresh; cleaning out the condensers and lines, replace the above mentioned parts, and replace all seals, then the normal A/C service to LR spec.

Moving from the coast the valley, you become appreciative of vehicles with A/C. I converted a few non-A/C cars of mine to know the basics of installing and servicing these things.....it's also good to know someone in the business for troubling shooting help...
