Assuming you are talking about a 96 or newer 134a system; There are two valves that enter the system. Both are on the metal lines coming off of the compressor. They are different sizes and covered with small black screw off caps. When you get a recharge kit it will only connect to the suction side valve (smaller of the two) which is where you charge the system.
When you open the hood, on the left side there is a skinny pipe and you will see a valve with a green cap. This is where you put in the freon. When you buy the frion, it should come with a hose that just pushes on to the valve and shoots the freon into the pipe.
The freon has to be removed and the pressure released from the ac system. Then the valve can be removed and replaced. The system will need to have a vacuum pulled and freon put in again.
Connect a Freon gauge and Freon to the low side ac port. With the engine running and ac on high, open the valve and allow Freon to flow until the gauge reads full.
The low pressure port. look for a blue plastic valve on one of the lines.
right next to the compressor under the car
Connect a freon gauge and freon can to the low side ac port. Start the engine and turn the ac on high. Open the valve to allow the freon to flow until the gauge reads full.
The schrader valve located within the low pressure side of the AC system.
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.
Freon goes into the low pressure side of the air conditioning system. The attachment from the gauge used to put the freon in will only attach to the low pressure valve so it would be pretty hard to do it incorrectly.
Contains no (R12) Freon. Freon was banned in 1996.
yes on the pasinger side of your car you will see a silver thing on top there will be a black cap tack off then there is a valve like a that looks like your tier valve just shorter get the freon from auto zone and flow instructions
The small valve on the accumulator (the canister) is wre you put the freon in the 1997 Chevy Astro Vans.
Should be a valve like a tire valve on one of the lines near compressor. Use the one with a blue color code (low pressure side)
No, it should not leak freon because it is supposed to be a sealed unit.
Where do I put freon in a 2007 chevy impala
where do you put freon in on a 2000 gmc jimmy
Connect a freon gauge and tank to the low side ac port of the 97 DeVille. With the engine running and the ac on high, open the freon valve. Shut the valve when the ac gauge reads full.
It is either on or near the recievr dryer in the right rear of the engine compartment. To corrrectly add freon, you need gauges and a refrigerant recovery system
Low pressure side larger hose Get kit at auto parts--comes with directions bring it to a shop that has the proper equipment
Underneath the car. no need to jack the car up. its a blue valve
It does not contain any Freon.
Look for the port(s) on the ac lines. they work like a tire valve. Should be a round blue thing.
SHould be 1 port each side like a tire valve to charge, you just plug into them to pressurize
You don't, cars haven't used freon since the 70's, you are looking for R-134, and it goes into a steel tube with a small valve stem, good luck it is buried in the front of the engine.
