Where is the low side service port for the air conditioning system?

Look close to the fire-wall in the area under the driver's-side windshield wiper. If you're adding refrigerant with the system from an auto-parts store, the fitting on the hose will not fit the high-side port, only the low-side port. Also, there should be a black plastic cap on the low-side port.

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

Where do I hook up a air conditioning recharge kit

If you follow the a/c lines on your vehicle you will notice that they are two different sizes. A larger diameter which is the low side and a smaller diameter which is the high side. Charging of the a/c system is done through the low side. If you follow the larger diameter hose/line you should notice a service port covered with a plastic cap at some point. That will be the low side service port and where you fill the a/c system. The two service ports on the a/c sys

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

How do you service a 2000 s-type jaguar air conditioning system. where is the low side or do you nservice thru trhe high side This is a great web site to look at for your air cond. needs. It's easier for you to see and read than to explain the in and outs. It's very easy to recharge. Just remember to use the low side port which usually the hose will fit on to only one fitting to your air cond. You do not want to hook up to the high side even if it were possible.

Need to refill my Air Conditioning (99 Passport). I would like to save money and do it myself. I have a can of 'Quick Cool' that has a sleeve to go on the low side service port. This is what I'm looking...

You can find the low side by turning on your A/C and touching the metal line next to the port, if the line feels ice cold than that is the "Low Side".
