There are 2 ports, use the large one. This requires the compreesor to run and it may also have a 1/4" service valve wihich has to be opened as well. if too low you will have to use a jumper on the plug for low psi shut off on the bottom of the gizmo. Just did all this on a 93 jeep

Location of ac low pressure port location 2004 chevorlet avalanch

Look back on the firewall for the two a/c lines. One is large and on is much smaller. The larger line is the low pressure line. Follow that line back to the compressor. The low pressure port will be on that line.

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

Where do i put the R-134a in on a 2002 volvo s60

On the low pressure valve located between the compressor and accumulator. The low pressure port has a black or blue cap covering the recharge valve. Don't worry, you can't connect the hose to any other valve port but the low side, the hose end is different from the high side. The high side has a red cap, and is not a recharge port.

How to recharge a 2005 volvo s40 with r-134a

hook up an ac machine to the low side port only which is located behind the passenger side headlamp in the engine bay. evacuate the system then vacuum it for 15 min then recharge it with the specified amount of refridgerant. there should be a yellow sticker in the engine compartment telling you how much to add

2002 tahoe air works fine but the rear air blows hot

either the refridgerent charge is low OR the expansion valve for the rear a/c is bad. I would evacuate the system and recharge it with the right amount FIRST before trying to diagnose another problem. should be a decal under the hood for correct amount of 134a

R134a recharger nozzle won't fit on low pressure service port.

The low pressure port on the 2003 grand am is actually behind the engine, near the firewall on the passenger side. Good luck getting your hose down there though, I ended up buying an extension hose.

No air conditioning-needs recharge- with what?

There are a lot of products out there for recharging cooling systems. R-134a is the current coolant that is being used. Wal-Mart and most other parts stores will have an easy to use recharging kit built for r-134a ready systems (a 1998 would have the proper seals and oils).

What recharge A/C refrigerant is used for a 1999 Chevy S10 pickup

On a 1999 s-10, your correct refridgerant is r-134a. I don't understand why wisconsin won't allow you to purchase r-134a at a auto parts store. R-12 is the refridgerant that has been banned in the US, and requires ASE air conditioning certification to purchase. I've never heard of any law anywhere prohibiting the purchase of r-134a.

Anyway, your system is a r-134a system.

I hope this helps you, and I wish you luck on your repair.
