SOURCE: I want to add refrigerant to my 2005 Buick

It depends on the size of the cans!

The low side is the "thick" pipe that comes straight out of the inside radiator (evaporator) to the compressor, the high side is the thin pipe, running from the compressor to the outside radiator (condensor), then the liquid receiver (the part that looks like a soda can) Add a can of freon while the car is running with a/c on, check the sight glass on the liquid receiver the whole time. If there is enough freon in the system the sight glass should look almost full. If it's not enough, add another can.

SOURCE: locating the High side and Low side AC gas ports

Easy. find the compressor. The larger hose attaching to the compressor is the "suction" side. This is where you install the refrigerant.

The smaller hose, whether rubber or metal as it travels to the passenger compartment, is the high pressure side.

After installing refrigerant and as the compressor is running, the larger hose will feel cool and the pressure side will feel hot.

Where is the opening to add freon on a 2000 buick lesabre


I have a 2000 Lesabre and it is located on the passenger side of the engine compartment right on top of the Canister. There are two ports, one is larger than the other and both have a threaded plastic cap on them. The smaller one is the low side where you can check your R-134 pressure. Start engine and run the A/C on MAX. Remove the plastic cap from the smaller valve connect your gauge to that valveFollow the instuctions and tempurature specifications on the R-134 package. f9068a37-e087-4f01-b346-ecdafc697251.jpeg 587e478d-1464-4e2e-8ad9-44bf76552d6f.jpegThere ya go man, as you're hooking up the refill line hit the trigger so u don't allow any air in the lines instead of just straight freon.

Where is low side port to connect charge kit on a 1998 Buick Century Custom? Also, to be sure what type of refrigerant should be used? (R-134a) or different Thank You, Brandon


1998 Buick Century is factory-equipped with R134a refrigerent.

As for the service port, you just have to look for it. Not even the factory service manual will tell you exactly where it is located. It will be either on the accumulator itself or in the low pressure line between the accumulator and the compressor. (see diagram)

You shouldn't be working on Air Conditioning

You obviously have no knowledge or training

Take it to a repair shop ,so you don't do more
harm than good & you will, if you try to add refrigerant
only to have it leak out & polute the atmosphere
