The low side fitting is smaller than the high side so you cannot make a mistake attaching the connector that's on the charge hose. the port is located on the line between the accumulator and compressor.

    thank you. I'm glad that both ports aren't the same size. Kind of idiot proof

SOURCE: Trying to locate the air conditioning low side

This job requires special tools and special training. If you lack either, you risk SERIOUS personal injury. Injury comes VERY EASILY!

You need to address oil levels, proper and legal refrigerant recovery, system evacuation, and recharge.

You were planning to also replace the receiver/dryer, correct? It also needs the oil in it measured and incorporated into the amount of oil (in %) that would need to be added. FAILURE to address these and other issues will guarantee premature system failure and likely compressor damage.

Take this job to a qualified shop.

Sorry

Where is the low pressure air conditioning service port on a 1998 Buick Skylark?


Locate your AC compressor.
The low pressure service port is located on the back of the compressor where the high and low side connections bolt to the compressor.
Look on this line about 4 inches or so back on the line.

Hope this helps.. Best of Luck

Tip

Air conditioning


When an vehicle's air conditioning system has not been used for several months, the seals within the system start getting dry. I've never worked on a Peugeot 206 or any other peugeot before, that's why I had no idea where the low pressure ac port was. The high pressure ac port is the easiest to locate, because it is in the engine compartment, facing the car from the front, on left side of the radiator. The low pressure ac port is in the engine compartment, facing the car from the front, to the back in the center, under the windshield. The low pressure ac port and the high pressure ac port both have black dust caps. The low pressure ac port is the smaller of the two.

2003 ford explorer where is the low side service port


The low side service port for your air conditioning system is located

on the top of your A/C accumulator (can). It is located on the passenger

side of the engine not too far from your heater fan motor. It has a plastic

cap covering the valve.

How to recharge recharge airconditioner


Hi, determine if your car uses R134 or R12 refrigerant. You will notice screw type connectors on the both the High Pressure Side and Low Pressure Side lines in models using R12 refrigerant. R134 compatible models have quick connect valves on both sides. Models made before 1995 may use the old R12 refrigerant. If this is the case, you must have your Chrysler's air conditioning system retrofitted to use R134 refrigerant. Mixing R12 and R134 refrigerants is dangerous and may cause damage to your vehicle. Check your air conditioning system pressure using an automotive air conditioning pressure gauge. Keep in mind that in order to get an accurate reading, the air conditioner has be turned on the coldest setting with maximum blowing power. Remove the Low Pressure Side port valve cap and set it aside. The location of the port varies, but it is usually in front of the engine block. Attach the refill hose to the port on the Low Pressure Side of the air conditioning system. The Low Pressure Side port is smaller the High Pressure Side port. Because the ports are different sizes, the refill kit hose should fit only on the Low Pressure Side port. Additionally, the High Pressure Side port will usually have a red cap or be marked with an H or the word High Allow the air conditioner to **** the refrigerant out of the can by slowly turning the valve on the refill kit hose. Pay attention to the way you hold the can. Most kits will have you hold the can upright when you recharge the air conditioning system. It may take as long as 10 minutes to empty a single can. Turn the valve to the off position and remove the refill hose from the port. Recap the port before closing the hood. Let the air conditioner stay on for at least 30 minutes. This allows the refrigerant to move throughout the entire system.
Take care

Air conditioning port cant find it to recharge,


If you reach up under the fender on the front passengers side in front of the front wheel, you will feel the reciever dryer(accumulator) assembly. The low side a/c port is located there(not the best place to have it in my opinion). The high side port is located where the front grill meets the upper radiator support.
I hope this helps you out. And also if you are looking for a leak, check the snout seal located under the outer clutch disc. Remove the compressor clutch disc and check for leakage. The compressor bodies themselves were also known for leaking.
Good luck

CHARGING THE AIR CONDITIONING SYSTEM Where is the valve to connect the refill cylinder?


not sure what you mean by refill cylinder, but there are two ports to charge a a/c system, low side and high side, you fill on the low side, if you are using a can you bought from wal mart or a auto parts store than most come with a small hose that connects from the can to the port, you cannot mess it up, the hose will only connect to the low side port, the high and low side ports are two different sizes, one is located on top of the engine by the suge tank area, the other is located/accessed from under the front right of the car, look for a big hose coming from the a/c compressor and just follow it till you find the port, the big hose is your low side hose.

Location of low pressure air conditioning port?


Follow the biggest a/c line from start to finish.Usually the a/c port is located near the firewall.I have seen the port located under the passenger wheel well.There should be a decal that states the type freon on or near the fan shroud,core support or on the under side of the hood.It is most likely to be type r-12.You can purchase an r-134a conversion kit. If you are not a/c certified to use r-12,you do not need certification for r-134a.
