AC booster recharge hook-up

2001 Saturn L-Series, need to locate low pressure service port on compressor. Bought an AC booster recharge hose with gauge and R-134a can. I can see both ports, but the gauge for the booster only fits one port. Want to make sure I am attaching to the correct port. Couldn't find a picture of the compressor online to make sure I have identified the correct port. Is it usually located infront or behind the engine?

You can only attach the the recharge hose from the kit to the low side ( A/C service port) and the cap should be blue with a leter L on it. Good luck and follow the instruction and don't over charge the system. With the AC on the coldest setting, use a thermometer in a middle vent. Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience. If normal gauge readings are obtained and the vent air is cold - STOP don’t overcharge the system. The only proper way to remove refrigerant is with a AC recovery machine so if this is being done at home I can’t emphasize enough not to over charge the system. And actually the best way to insure the proper charge is in a system, is to use an AC machine to recover the R134a and then evacuate and recharge the system with the correct amount. Most cars have the specified amount on a decal under the hood.  Good luck and hope this helps.

It is usually in front. and the connector on the hose from the quick charge kit will only fit on the low side. they did this on purpose, so you cant put it in the wrong side

I am trying to locate the low pressure port on my 2000 Saturn LS. there is no cap on the only visible and accessible port I see. It is located in the front of the engine compartment (passenger side) but...


The high pressure port is much larger than the low pressure port. It is impossible to hook a charging hose to the wrong port. If the charging hose is leaking, it is either because it is not clicked all the way on the port or the charging hose connector is defective.

The high pressure port is located on the discharge hose just to the rear (driver's side) of the A/C compressor.

How do you connect a/c charger to make your central air cooler


The 1998 Dodge Caravan ac should be charged at the low pressure service port. This port is located on the suction line near the compressor. The suction line can be identified by it's size, it being the larger of the two line connected to the compressor. You must purchase a recharge kit at your local part store, which should include charging hose with pressure gauge and a can of R134a freon. Gloves and eye protection should be worn during servicing.(freon can freeze your eyes and cause frost bite to your hands). Connect freon to charging hose, connect charging hose to low pressure service port, open valves and start engine, turn on ac. If compressor won't start it may be required to disconnect the low pressure switch and jump out the connector.

Where do I hook the R-134 freon up to charge the system? I can't find the valve to hook up the freon, where is it located


Follow the large tube/hose coming out of the dash to a large aluminum canister that then has a hose or tube that goes to the compressor. It is probably located on the side of that canister (the accumulator) under a little blue screw on cap.. WEAR EYE PROTECTION AND GLOVES WHILE HANDLING REFRIGERANT!

2000 Saturn SL1, need to locate low pressure service port on compressor. Bought an AC booster recharge hose with gauge and R-134a can. I can see both ports, but the gauge for the booster only fits one...


The gauge only fits one port so you can't hook it up incorrectly basically. It wasn't always that way. The old days with r-12 you could make a mistake but car manufacturers finally did something about it. I know the first time it's a little scary, but after you do it,no problem. Have fun!

How do I add coolant to the air conditioning system of my 2001 Hyundai Elantra?


You need to locate the low port on the AC.

You recharge the AC connecting to the low port.

You find the AC low pressure at the top of the compressor. Near the compressor you find two ports, the high port and low port.
You can follow the compressor line to reach the port.

To find out which one is the low port, run the air conditioner for a couple of minutes withthe engine on.
Then turn off the care and touch the lines from compressor to the two ports , often covered with plastic caps. Only one of the pipes will be cold, the line that is cold will lead you to the low port.

Where do I recharge ac at


there are 2 ports one for low pressure and one for high pressure. the low pressure is bigger in diameter and is usually close to the dryer and or fender and firewall. the high pressure is near the condensor on the fron of the vehicle. if there are caps for the ports low will be blue and high will be red. low side pressure should be 35-50 psi and high pressure should be 135-150 psi

AC has stopped blowing cold air. Compressor is working. Where is the recharge valve located?


There are two A/C refrigerant lines. The small line is your high pressure line and the larger line is your low pressure line.
Start at the fire wall and follow the "large " low pressure line to the compressor. The low pressure charge port will be some where on that line.
DO NOT try to recharge on the high pressure side ( small line )
Good luck, let me know.
