your supposed to b certified for that and if you dont know where the valve is its unlikely u are
Another Perspective
Certification is primarily necessary for anyone using the old Freon. The requirements for 134-A are much less restrictive.
To find the schrader valve, follow the refrigerant lines out of the AC compressor. One is the "high" side, and the other is the "low" side. It's pretty obvious which is which, since the high side goes to the condenser (attached to the radiator) that means that the OTHER line is the low side.
On the older Saturn S series, the schrader valves were right next to the AC compressor, but you had to search on the L series. Just follow the AC lines either way from the compressor and you should be able to find the schrader valves.

What kind of freon do you add to a 2004 trailblazer?
R134a
How can you make a 1996 Saturn air conditioning blow colder air?
Add coolent add some R134a but don't over charge, you will blow the ac compressor seals
Where do you add oil in a 1997 Saturn s series?
There is a cap under the hood on the valve cover that says ADD OIL HERE
How do you put freon in a 2000 Saturn ls?
You don't. The 2000 Saturn refrigerant is not Freon R12 it contains R134a. Add it at the Low pressure port. You have a leak or it would not be necessary to add refrigerant. It is illegal to add refrigerant to a system with a leak without first repairing the leak. Take it to a professional and have the leak fixed.
Where is the valve located to add freon on a 1993 Saturn?
Low pressure line from the compressor (Larger hose)
What is the difference between r134a and r134a plus?
The 134a plus just has PAG oil added already, so that you (theoretically) don't have to add it after adding the R134a.
Where do you add power steering fluid on a 2004 Saturn vue redline?
there is no fluid to add its a sensor i had to go get it replace kinda weird huh
How do you add freon to 2003 Jeep Liberty sport?
add r134a to the service port
How do you put R134a in a 2002 Saturn SL?
To add R134a to a 2002 Saturn SL, first ensure the engine is off and the AC is set to the maximum cool setting. Locate the low-pressure service port, which is typically near the AC compressor; it has a larger diameter than the high-pressure port. Attach the R134a refrigerant can to the low-pressure port, following the manufacturer's instructions, and open the can while the engine is running and the AC is on to allow the refrigerant to flow into the system. Monitor the pressure and avoid overfilling, as this can damage the AC system.
What kind of freon to add to a 1999 Taurus ac?
R134a
How many valves are there to put freon in a 2000 ford expedition?
There is one valve that is used to add refrigrant. But you had better not add Freon. Freon is R12 and your vehicle's A/C system does not have Freon (R12) as a refrigrant. More than likely it uses R134a.
Where is the low pressure air conditioning service port on a 1990 buick lesabre?
I highly recommend taking it to a service station because you will need to have it retrofitted and the freon changed to r134a instead of r12 ---- DO NOT ADD r134a to r12 it will lock up your compressor ---- But the low pressure valve is the one closest to the firewall it will look like a tire valve stem. The high pressure is located closer to the ground.
