Question about 2006 Chrysler PT Cruiser

1 Answer

Finding out whether there is a lower connection that I can connect the freon hose to

I just purchased a freon gauge and hose too hook up a can of freon to the cruiser. The male connection on the car has a connection that fits the hose perfectly, so I connected the two together. I opened the can, and read the gauge, which showed the release of freon. The car was running and the AC on full blast. After about half of the large can, the AC still blew hot air. Did I have this connected to the wrong place?

U may have overcharged the system, what is the pressure reading on the low side, the hose will only hook to the low side line, the fittings are different for each line, lo and high side..

How many bottles of refrigerant a volvo s80 takes?

That's a REAL GOOD question! The factory refrigerant charge specifications for your vehicle is 2.20 Lbs. of R-134A. Freon R-134A comes in 12 oz, 14 oz, 16 oz, 19 oz, and 22 oz cans (as well as 30 Lb Cylinders) - it depends on which brand/size can you are buying, whether your system is COMPLETLY out of freon, or whether it still has some freon in it.

The best way to deal with the situation (in my opinion) if you are going to try and charge you own A/C system is to purchase a kit that comes with a gauge. A company called interdynamics has a real good kit available that comes with a reusable gauge. Once you have the gauge, all you have to purchase in the future is the freon itself. By using the gauge, you can more accurately charge your system without the worry of possibly overcharging. (Overcharging can cause extremely high pressures that can do serious damage to your vehicle or cause personal injury.)

Anyway, this kit is available at O'Reilly's as well as other auto parts retailers. Here is a direct link to see the kit at O'reill'ys web site.

There is also a whole bunch of instructional videos on how to charge your system at the interdynamics web site. CLICK HERE

I have a 2006 Envoy, and it appears to freon is low. I purchased a can of freon from Auto Zone. Tried to put the nipple over the lower valve and it won't connect and snap in. I end up sending freon...

ok, there is a high side, high pressure line, and low side, low pressure line, for your AC. That refill can you purchased has an R134a connector. It will only connect to the low side of teh AC system as they are different sizes. If you try to connect it the best case scenario is what you described, the connector won't lock in place and it sprays every where. The worst case scenario is the can blows up. Make sure you have the can completely connected and the connector locks down or your on the wrong valve and may damage your system or injure yourself.

You need to check the freon level and if that is good check the compressor. If you have no pressure on the low side, when I say pressure on low side I mean vacuum, then most likely the compressor is bad or you have a leak someplace. You can get a freon fill kit at Walmart, Target, Auto Zone and most any auto parts stores. These kits comes with a gauge and connection hose. Typically if the freon is low the compressor won't activate. Connect the fill hose to the low Side of your AC and turn the AC on to Maximum with the engine running. If its a low freon problem the compressor will start to kick in as the pressure increases. Make sure you don't overfill the system as this will cause a seal or line to blow. Being a 1998 your vehicle should use R134A freon which is what can legally be purchased by a home mechanic. It cost about $12 to $20 a can and usually includes a leak detector additive and seal conditioner.

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 install the freon on my 2000 lincoln town

We bought a hose and freon and the hose doesn't seem to fit right. Can freon be refilled at home?

Make sure you have 134a coolant and gauge with lines to fit 134a NOT r12 or r22!!! And then there are 2 lines upper and lower, if you have the right hose you might be trying the wrong port.

To diagnose problems, an A/C manifold gauge set is needed to read high and low side pressure readings. Avoid adding refrigerant with a simple charging kit like the ones sold at parts stores. Don’t add any stop leak, this can cause problems in the compressor, expansion valve or condenser.
Keep in mind that using an A/C gauge set and seeing BOTH high and low side readings can help in diagnosing the problem when you know what to look for. First, on a 134A system the high and low side service ports are different sizes. AC gauge sets have color coded hoses, the blue color coded hose has a connection that fits on the low side service port and the red hose has a connection that will only fit onto the high side. The yellow hose won’t hook up to anything if just checking the readings; it can be used to connect to a vacuum pump or attached to a refrigerant can or tank.

Normal readings on high and low side with AC OFF (static pressure) - Depends on outside temperature, but normally is between 80-105 PSI
Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s - Ranges from 25-35 PSI - Note that on many Chrysler products a normal reading on the low side may be 15-25 PSI
Normal high side reading ranges from 200-350 PSI

Don’t assume that if adding little Freon is good that adding a lot is better!  Overcharging just a little can decrease the performance of the system and possibly damage the compressor.

Both low and high side readings are lower than normal, this indicates a cars AC system is low on refrigerant and is under-charged.
If both low and high side readings are too high, this indicates an overcharged system - too much refrigerant. This also can indicate that the condenser fan is not working, is too slow or the car is overheating and heat is transferring from the radiator to the condenser.

Good luck and hope this helps, keep me posted be glad to answer any question you may have. And yes the A/C system on your car uses R143a and there is a A/C pressure switch along the low pressure line or on the accumulator, it looks like a oil pressure sensor with a two wire lead cliped on it.

How to put in ac gas

Easiest way is to purchase a kit from your local parts store. A kit usually comes with one or two 150 ml cans of freon and a hose kit with gauge (plus instructions). The cost should be around $40. The intake valve on the A/C under the hood is a universal valve that the hose connects to, and the other end connects to the cannister of freon. Be careful not to overfill - monitor the pressure gauge - as you can trip the shut off switch and shut down the AC altogether.

#1 you will need r134a freon. #2 the low side service port is located right at the firewall where tha line goes to the evaporator. #3 if wou bought a can of 134a freon with a hose that will hook to it, it will work. all service fittings for 134a freon are the same even though the high side and the low side will always differ
