What kind of ac coolant does it have 134a or r 12 and where is the low pressure port for the ac located


Depends on the year. Cars in the early 90's used R12. Anything later uses R134a. The size of the charge ports will define the R134a port. An adapter is needed to fit on the charging hose. R12 requires no such adapter. Ther charging label under the hood will tell you what refrigerant is needed too. Since you failed to give enough information on what make and model car you have, a general answer for the location of the low pressure port will be given. On the compressor, the larger diameter hose connection is the low side. Connect there, or look for the drier/accumulator (Large diameter silver container near the firewall). Connect there. You will need to access the AC information label under the hood to determine how much freon to add to the system.

Where is the low air pressure port on a 2004 Suzuki verona


on what?
tires?
is this a TPMS question, tire monitors?

all you said are and ment Freon (or A/C Refrigerant)
HVAC answers. (low pressure side, is large pipe)
there are 2 ports. each a different size. (big is it)
the tool in hand the Freon R134a can and hose.
has but one fitting (walfart setup)
you look under hood. and see, the 2 big lines on compressor
its just 2 lines.
the one big line on the compressor is that line. Lowside.
and to fire wall it goes, and fitting,
on the way are 2 fittings, only one fits the hose.
they have caps.

here is a generic site, showing the same trick.

the walfart gauge only has 1, on left. low side

Where do I add frion to my 2003 chevy malibu


To the suction port, or low pressure side of the system. If you do not know what one that is, you might want to get some help. You need to have the proper amount of freon in the system or there could be compressor damage.

Replaced all A/C major components (compressor, filter-drier accumulator, and orifice tube) except condenser due to a seized compressor and failed clutch bearing. Flushed system and appeared to have no...


It sounds like you've done just about everything except to check if there is a bad or intermittent wire causing this or perhaps your low-pressure safety cutout switch is possible going bad causing the compressor to kick on and off?

Air conditioner does not cool in 2000 Yukon.How do I check freon level and how to replace freon if need be


Get an r134a refrigerant add kit from Walmart or your local auto parts store.

You can even get a can of Arctic Freeze by Intermatics that has a hose and a gauge on it.

Connect the hose to the low side port. You can find this port on the 'thicker' piping that comes off of the compressor (versus the thinner piping that comes off the compressor which is the high pressure side).

Pressure should read 25 psi to 45 psi on the low pressure side when the compressor is running and the a/c is on.

Pressure should read 75 psi to 100 psi on a hot day when the car is off.

However, you'll want the a/c to be running when you add freon.

Press the button on the can to install more freon, if needed.

Where is the ac lowside port located on a 2005 gmc savanna van


The low side port of the 2005 GMC savanna Van is located on the low pressure side of the compressor.

This is found by locating the compressor driven by a belt that has a clutch that engages and disengages as the a/c cycles.

The low pressure piping is always in the larger diameter piping, and the high pressure side is always contained in the smaller diameter piping.

Therefore, follow the thick pipes from the compressor up to the accumulator, which looks like a large can of soup. On the accumulator receiver/drier is a port that connects to the tube that is connected to the can of r134a freon refrigerant.

Simply quick connect the tube to the low side port, which is located on the 'thick' tubing or on the accumulator and then fill until the low side pressure is 25 psi to 45 psi while the compressor is running.

When the car is off and the compressor is not running, the pressure should be 75 psi to 100 psi on a hot day.

Hopefully the system doesn't have a leak slow or fast in it.

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.

On my 2003 Chevy Silverado, the A/C compressor won't kick on. Just blows out warm/hot air.


The ac system may need freon added,if the system is low,or out of freon,it will not allow the ac compressor to come on.
