Location of low pressure ac valve and type of refirgerant on 2003 chevy monte carlo with 3.4L

Normally todays refills will only fit one size Schrader valve size so look at the dry and the line coming to it should be the low pressure side of the system. Just be sure you fill fitting fits the valve.

could anyone tell me were the low side port is to charge the ac in a 1998 monto carlo

Find the dryer, A round long cylinder. Might be up by the fire wall on the right side or even in the fender well area. Just have to look around.

The low pressure port in the AC system is between the evaporator which is in the heater/AV housing in the dash. The line between that part and the compressor is the low pressure or suction line. You should find a connector in that line that has a cap on it. When you take the cap off, it is a snap on quick disconnect with a "tire stem valve" in it. Be sure to screw the cap back on with you are finished.

It's number 12 on the picture. Located under the MAP sensor.

Re the a/c. Get a can of red tek sealer. make sure the engine is cold or you won't get the connector on to the low side port to seal properly. Follow the insrtuctions that comes with the can. Just adding the refrigerant doesn't stop the leak

the sensors are on each tire [its part of the valve stem] if warning light is on -one of tires need air also check pressure in the spare tire

your a/c freon has a low pressure devise that will not enguage the compressure you can buy 1 or 2 cans of 134 freeon and connector that well only fit on 1 of your freeon lines your a/c must have a leak in it your best bet is a repuable a/c shop good luck CJ

Check Autozone.com. There repair section should have the torque specs and order of tightening.

hello dsouris: Locate the A/C accumulator on the left inner fender well. This will be a round aluminum cylinder with two lines coming out of it. Follow the large line that runs back to the firewall. You should see a shadder valve in this line. This will be the suction line or low side line. This will be the line used to charge the A/C system. If you need further help please just ask.
