There should be an aluminum line around the engine top portion with 2 black caps on it.Remove the black cap nearest the belt system.That is the fill point.With the engine running and a/c on,fill the line at one quarter can intervals and check.Once it is cold enough stop.Overpressurizing the line can cause damage $$$.If you try to fill the wrong side it will not hurt the system,it just won't accept the freon.If the coldness goes away fairly quick,1 week or less,there is probably a leak in the system and will need to be checked out.Good luck!

Are we talking about a/c? if we are look for the a/ compressor and you will find the tips on the pipes coming from the compressor to the other parts of the a/c system it should have one black and other blue caps,that will unscrew off to show you the valves

During the replacement of my radiator, the ac line was knocked lose. Do I need to a specialist to refill the freon? I have a 2001 300M

The correct answer is "yes".

The backyard mechanic answer is this:
Reconnect all hoses.
Use a recharge kit with the engine off and just put some pressure back into the system, keeping the Refrigerant can upright. Check for any leaks with soapy water by the repaired connection.

If no leaks, you know have to purge the system. The correct way is to evacuate the air with a vacuum pump. If you don't have that, the alternative is to remove the kit from the charge port. Carefully press in the small pin in the center of the port to open the valve and release all the gas you just charged in. Refill again like you did the first time, DONT run the engine, just let the refrigerant can pressurize the system again. The bleed it off again. Repeat this several times.

Each time you do that, you dilute the air that may have gotten into the system, and increase the percentage of refrigerant vapor. After about four or five times doing this, most of the air and moisture should be removed. Refill the system as described on your refill kit and you should be back in business.

Note: don't this with R-12 gas, it is an environmental hazard, R134a is not.

Where thr vaule for ac to refill

There is no valve. There is a small yellow cap on the port where you refill the R-134a. Sometimes they have a tag on them. But it looks like a big valve stem like on the tire. Remove the yellow cap and you hook the line from the can to that. You will have to shake the can while filling. And also have the a/c running when you are refilling. Otherwise the pressure won't bleed off of the compressor and it will not receive any on the new R-134a. Be sure to shake the can while refilling. Some of the refill containers have gauges on them. They are the best to make sure that you are getting the refrigerant in the system.

Rate 4 thumbs up if this helps!!! Thanks!

1998 Cadillac Deville low refrigerant a/c

I have a 1999 Cadillic Deville. The low Frefrigerant indicater come on after about 15 minutes of disconnecting the battery power. Each Time I reset the power the air conditioner comes back on for a while then goes out. I have taken it into the local auto repair place and they find no problem with the unit.
Could this be a intermittent connection to the computer. They have replaced both sencors and the problem persists. Where is the computer located on the car that handles this AC sensor message?

My 1988 toyota camry: airconditioner/heat doesn't work

The heater may not work because of a bad thermostat, low coolant, or a bad sensor at the engine. It can also be a bad resistor valve under the dash. The resistor valve is connected to a wire plug on the blower motor under the dashboard. It needs to be replaced. Th AC may need to be refilled with refrigerant or the compressor may be bad.
