My ac started blowing warm air, and I think it's low on freon (or whatever it's called now-a-days) I've always taken it to a shop to have it recharged, but I'd like to do it myselfthistime.Istherea write up with step by step instructions on how to do it?

 

Just buy the 10-15 dollar hose with the pressure gauge on it and a can of freon. You don't have to buy the super duper leak sealer kind, just get the $10 can at walmart.

Screw the can onto the hose, locate the drier, its the shiny silver can on the passenger side of the engine bay, there will be a black cap just behind it on the line, unscrew it, connect the hose and fill her up! In this heat, pressure should read around 55psi I think. Periodically shake the can to make sure you get it all in there. It's really pretty easy.. oh yeah, make sure the car is running with the a/c on max (full blast). The drier and hoses should be sweating when you are done.

If it blows hot in a couple of days you will know it has a leak that needs attention. If that happens, then you have a little more work to do..

 

Wow, if it's that easy, why does it cost $80+ at a shop to have it recharged?

 

Shops just love to bend people over. I would pay 80 bucks to get my tires rotated before I got them to charge my a/c lol.

One thing shops are good for is flushing the system, but that's necessary only if your compressor takes a dump.

 

Well good to know! Thanks. On average, how many cans do i need to recharge it?

 

No problem. I would just start with one and see if that does the trick.

 

about 1

 

Because they usually pump out all of the old stuff and pump in all of the new stuff; but more because they have to pay overhead on a building with lifts and techs, etc and it's easier to make it up on the little stuff than on the heavy line stuff.

Just like when you go to best buy and pay $60+ for a Monster HDMI cable that cost them $2.50, but can pay $800 for a Laptop that they paid $775 for.

 

I usually read the can that has diagrams and instructions.

One can.

 

Were you trying to be smart with me?

 

I can help you out at lunch time if you want lol

 

^
watch out. he'll probably blow up your engine.

 

Maaaaaaybe!

 

when you do it , get a hot pan of water about 3-4 inches deep with hot hot water and rest the can in that when you do it , the can will get cold and probably wont let it all out .

 

Laying it on the header will yield the same results

 

I just replaced my compressor 2 days ago and did this. Well it's warm now...so any suggestions as to find the leak and how to fix?

 

UV dye and a black light.

 

did you evacuate the system ? Did you oil the compressor ? You could recharge it and have the dye already in the recharge can . So you can see if there is a leak

 

Sry to hijack Josh!!!

But no, I did not oil the compressor. I just did the same as when Inspector12(jeff) helped me replace my last one. This was my first solo attack on it. If there is leak I prob just need new line? Thanks for all help. And Josh, it's super easy to charge. Like they said and can shows <---not bein smart *** lol

 

Lol, just did it and it was very easy. Thanks everyone.
