Diagram of low pressure port valve on 1996 ford ranger air compressor


If you don't know the difference between "coolant" and "refrigerant", you probably should not be fooling around with the A/C, it can be dangerous. And yes, words do make a difference. That is how we communicate. The best thing you can do if you want to work on vehicles, is get some books and educate yourself. The low side port is going to be somewhere between the compressor low side (the larger line) and the accumulator/dryer. Find the line and follow it. It can't be too hard to find as it is a general service port.

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.

Want to add refrigerant. air conditioner not very cool. which is low pressure port for adding r134a coolant?


The newer cars have 2 ports. The large port which is the high side and small port, low side. The kit you buy to refill the air cond will fit only one of the ports and that's the small port. You don't want to hook up on the high side so, this is why ports are sized and the gauge will only fit one. The low side should be near the evaporator or on the evaporator.

Low side port for air conditioner


If you are recharging the air conditioner - start at the A/C pump, and follow the lines up until you find a black round stub (this unscrews) and this is where you will re-fill (recharge) the A/C.

NOTE: It is recommended to have a professional (certified) mechanic recharge A/C systems, but is not necessary. (laws and regulations vary per state, city, county).

Please let me know if you need further assistance.

How do I fill air conditioner coolant.compressor is new, but I need to add coolant.


You need to evacuate mositure with a vacuum pump and then add a can of r134a with oil in the can. Then add more cans without oil. Up to the amount on the decal under the hood.
The low side charge port is behind the passenger fender well. Remove tire and the 7 fasteners holding the plastic fender liner in.

Where is the compressor on the 95 Roadmaster?


you add refrigerant to the low side port only, which faces the front right side of the engine compartment. The aluminum can has 3 fittings on the back and one on the front, that one is the low side port.
