I did a lot of laptop repairs but this will be my first try at fixing cars...so I do not know yet what I can or cannot do. A step by step instructions will give me a better idea of how much work I will/can do.
thanks!
Assuming no system charge( as in ZERO), otherwise refrigerant will need to be removed by a shop with reclamation capabilities
Buy suitable vacuum pump.
Buy AC manifold gauge set and can adapter
Buy a candy thermometer 0 F - 220 F approximate range
Buy appropriate orifice tube
Buy orifice tube removal tool(you might get by without it)
Buy AC spring lock disconnector tools (may be more than one size?)
Buy O ring kit
Buy O ring lubricant
Buy correct schrader valves
Buy schrader valve tool for removal/installation of the valve cores
Buy R134A refrigerant
Buy appropriate PAG refrigerant oil
Buy replacement accumulator drier
Buy a book about AC theory and service too, it will help
Be prepared to buy a flush kit depending on the orifice tube screen condition
Now you are ready to begin to start unless I left something out.
Step by step? There's a really good sticky at the top of the AC section in Under the Hood as was pointed out previously. You really really need to go read through those before continuing. You must get the principles of the job firmly established in your mind.
Maybe you can find a specific service manual. I'll tell you now that the Haynes are pretty generic and leave much to be desired.
I'm not here to discourage you but to point out some fairly expensive specialty tools required that you may never use again. I believe it will be less expensive for a good shop to do this repair for you but it all depends on what you are willing to invest in tools and in learning how to do it.
