Just to make sure I'm recharging the right thing. When I'm standing at the front of the car looking under the hood, is it the valve closest to the front of the car on the right side?

The recharge tube should only be able to fit on one.

I managed to get it onto at least 2 last time I tried. The other was on the left side of the engine bay closer to the engine bay I believe. I didn't put anything in that one though. It is the one on the right by the bumper?

That's where it is on the zetec. I imagine the Duratec is the same. If your a/c is working at all, the low pressure line (where you inject the coolant) will be cold when the system is running.
Posted By: RyeLou Re: A/C recharge - 06/09/04 09:09 PM
It blows but certainly not cold.

So it turns out I have a leak somewhere. I got the recharge can w/ the meter on it. It read 0 so I filled it up (w/ car and a/c on) and it went into the blue. I stopped and went back to the car, still hot air. I turned the car off, and it sounded like the compressor was still on. I went back to the front of the car only to hear a serious hissing noise and I looked at the meter and saw that it was dropping. So...off to a shop for the a/c Anyone know about how much it'll cost to get the system checked out?

When you say...you got the recharge can...you mean you can buy a can of refridgerant? I guess thats only in the States...cause you can't do that in Canada...have to have an OZone certificate to purchase it.
Posted By: RyeLou Re: A/C recharge - 06/10/04 01:50 AM
Yep. You can go pick it up at any auto parts store.
Posted By: bentleywarren_dup1 Re: A/C recharge - 06/10/04 02:05 AM
If it was empty, it's going to take more than one can to fill it. However, I think you made the right decision when you decided to take it to a professional. If it's leaking, it's going to be very difficult to find it and fix it yourself. I fix most things myself on my vehicles, but I just took my Chevy truck to a mechanic for A/C repair. It's too easy to go wrong if you don't really know what's going on.

Places all over Houston (The A/C capitol of the US) that state "Free Air conditioning check up" or "Free Air conditioning inspection." How much you want to bet they find some high $$ thing needing done?

Would an empty A/C not let the compressor to turn on..?

I haven't checked mine closely yet, but when I turn on A/C it doesn't seem to even start the compressor. There certainly is no load on the engine.

Yes, every time. There is a low pressure switch that disables the AC if the freon pressure is to low. It is a protect for the compressor. Without this switch, the compressor would burnout because there'd be no oil (which is in the freon).
Posted By: daenku32_dup1 Re: A/C recharge - 06/15/04 07:47 PM
Thanks. Guess I'll be making a stop to buy some freon..

No you won't. You can't buy Freon (a registered trademark of the DuPont Corp) without special licensing. Besides, NO contour ever made used Freon.

Buy R-134a. It is NOT Freon.

In any event, the pressure from the the refrigerant can might be enough to close the cycling switch and engage the clutch. It takes about 45-50 psi to make the switch.

Sooo... my A/C Clutch keeps turning on and off, and giving me warm air out my vents because I have low R-134a?

Yep. That's what mine's doing (or was doing, as of tomorrow.. can't take the heat).

Same here... my A/C was somewhat strong when I first bought her... then she faded away... takes longer to get it cold then my moms escort...

Tell me how it works out
Posted By: TaurusKev Re: A/C recharge - 06/17/04 01:27 AM
Ummm... got a can, got the hose/connector, please verify i did this correctly:

Start car
Turn A/C on
Connect the can and make sure the top valve is open (mine has a valve on top)
Let run for a few
Unplug


I think thats the right order.... cus my A/C still feels alittle warmish... not ice cold like my moms escort...
Posted By: 99SVT_dup1 Re: A/C recharge - 06/17/04 03:14 AM
You should get a kit with a guage so you know where it's at.
Posted By: TaurusKev Re: A/C recharge - 06/17/04 03:35 AM
Got a gauge... dont work...
Posted By: Rogerm60 Re: A/C recharge - 06/17/04 03:43 AM
You should notice that the can gets cold and lighter as the freon is sucked out. If the can stayed full the service valve may not have opened. It's best that you get the gauge to work, or test it on another car to see if it works.
Posted By: TaurusKev Re: A/C recharge - 06/17/04 11:39 AM
Can did get colder, and lighter... but i still think not enough was added...
Posted By: Brett W Re: A/C recharge - 07/13/05 05:07 AM
Hey RyeLou,

How much did you end up paying to get your leak fixed? I just discovered my roommates 98 contour, which she just got, has a leak (somewhere directly beneath the low side valve by the sound of it) and was wondering if that's gonna be a lot to fix...
Posted By: todras_dup1 Re: A/C recharge - 07/13/05 02:59 PM
Doubt he'll read this. This is A YEAR OLD! He has sold his car.
Posted By: FavoriteMystaque Re: A/C recharge - 07/13/05 04:37 PM
Might be the accumulator can, they rust out. Located against the radiator on driver's side.
Posted By: Brett W Re: A/C recharge - 07/13/05 07:50 PM
LOL, oh! well yeah, it does sound like it's coming from the accumulator...
Posted By: richs_dup1 Re: A/C recharge - 07/14/05 01:20 AM
Could be the condenser. On my SVT had to replace the condenser and the conderser on the 97 has a leak right now. I'll be off to the junk jard to pick up a used one for that car. I put a new one in the SVT. Both leaks were on drivers side not to far from the top.

If wanted my A/C to work all the time I'd have to recharge it every day. I'm not sure what needs to be replaced and I think I might have to flip it to a mechanic for this one...
Posted By: Eric L_dup1 Re: A/C recharge - 06/16/06 03:01 AM
I Figure a few people might benefit from this post as it is again A/C season!

Is 1 brand/ can of R-134 better than another? The reason I ask, I need to recharge my Tour. Targe has a can with a pressure gauge and hose (all 1 unit) for $21.99 on sale. It was sittign right next to the small R-134 plain-jane cans. I don't have access to a hose or gauge so I thought this would be a good alternative.

What are your thoughs?
Posted By: Big Jim_dup1 Re: A/C recharge - 06/16/06 04:01 AM
They are all chemically identical. At the most there could be an insignificant difference in purity. If it is R-134A it is the right stuff.
