What size do you use to for the ac


Hello and if you are referring to the port size for recharging the system for AC it will be the smaller port, the low pressure side is what is used for refilling of AC in cars and trucks.
Hope this helps

How to fine the low port vaule to recharge air condition ?


Find the dryer for the ac and just before it is a Schrader valve that should be the low side of the ac. The refill cans you buy today will only fit on one of the valves. Good Luck

I need to find low pressure port on 1999 Labaron LXI for recharging ac coolant


Without A/C system theory & some training,
I would say no. Leave it to a mechanic with
the correct equipment

You can not just add very well with those wal mart
a/c kits

You have no way of knowing how much to add, without
a manifold gauge set attached to vehicle

If you need to add, you have a leak that needs to be
repaired & your poluting the atmosphere until the repair
is completed

Would the ac coolant need to be replaced in a 1986 model if I wanted to recharge it?


Yes, depending! You would have to get an A/C retrofit kit(basically all it is is a couple "adapters" for the old "refill" HIGH, and LOW ports)
From R-12 to R-134A
(Unless all of this is already done, OR you find someone with R-12 and the right equiptment!)
After you get the retrofit kit, you'll need to COMPLETELY flush the system, get new PAG oil, and refrigerant, get a vacuum on your seems, introduce the PAG oil, reinstate vacuum, and add your refridgerant!


If you could find someone with R12, and the equiptment for R12, it MAY be cheaper. and R12 gives a colder A/C

Recharge Auto air conditioner


I just did this for my 1994 Camry. Does your camry use the R-134A modern refrigerant? Probably.

Go to an auto parts store and buy a can of R-134A with a pressure guage included. You'll need that guage so you don't overfill the system. I bought one that allows me to save the guage and buy cheaper refills int he future.

There are two AC valves. A small one, located in the left-rear of the engine compartment, behind the strut tower, just in front of where the passenger seat is located. It might have a cap on it marked "L". This is the "Low" port, and is the one you want. The larger "H" port is up near the battery, is bigger, and is the "high" port. You don't want to use that one, and besides, it won't fit the can anyway.

Locate that low valve in the left-rear of the compartment. Take the cap off (if one is still on there). Start the engine and get it up to running temp. Turn on your AC to maximum cool, fan at maximum. Follow the directions on the can. It's pretty simple.

You'll pull back on the bushing on the refill line, and then snap it onto the valve just like you'd find on an air hose. Snap it into place, and then start refilling. Make sure the can is upside down and that you rotate and shake the can to get the coolant out effectively.

Help with ac recharge


If you have a refill kit, the hose will only connect to the low side hose. Most likely, the hose under the filter is the high side hose. Hope this answers your question. Best of luck.

p.s. When recharging AC, have engine running and AC on HIGH

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.
