It comes with step-by-step instructions, a built-in reusable installation hose, snap-on coupler, and air conditioning pressure gauge. These charge kits are not a cure all and most of the time they do not fix your problem. Step 10 - Disconnect the yellow hose from the vacuum pump and attach it to a new 134a refrigerant source. You should hear the pressure release inside the can. What is important is the safety of everyone from a possible fire or explosion caused by the contamination, and how you can protect yourself and your family. The canister will become ice cold, another good reason to wear gloves. That's a big-enough jump to prove that the product does work -- at least as a short-term fix.
Step 5 - Once secured, tighten the valve which activates the internal plunger that opens the service port valve to the refrigerant lines. Continue dispensing refrigerant and rechecking the pressure until the desired level is reached. Even while performing the check and removal of the old refrigerant, wear protective gear such as a mask, googles, and gloves. Next, start the engine and run the compressor and look at the pressure on the low side. The compressor is near the low-side port and looks like a pulley system. As a further safety measure, the ports are different sizes, so you physically cannot attach the pressure gauge or hose to the wrong port.
Bigger Problems Many recharge kits also feature a stop-leak sealer, claiming to fix and prevent leaks. Instead, take it to see a technician. If you are unsure if you need to take your car to the shop or not then give this product a try and see if you can solve the problem yourself, or at least put it off until next season. Provide details and share your research! Manual Recharge Basics Manual recharge systems do not evacuate the fluid in your system — instead they add refrigerant on top of your current levels. Locate the pulley on the compressor.
Locate the refrigerant fill port on the low pressure side of the system. But a friend had a 2009 Ford Flex that needed an air conditioning recharge, so I agreed to accept a sample to test. It is impossible for me to tell if you have a minor leak, a large one, or a failed compressor. If you have a vehicle made between 1992-1995, you may have either R-12 or R-134. If you want to top off the system you can probably just purchase a kit from your auto store and do it yourself.
Read the pressure displayed on the gauge again. Overcharging makes your system run ineffectively and can damage it. These laws concentrate on Freon that is harmful to the ozone layer. This type of refrigerant is no longer manufactured in the United States due to its negative environmental effects. There should be a chart in the package to give you, at least an idea of how much to charge. Make sure the compressor clutch is spinning.
The system is completely sealed and no refrigerant should be coming out of it. Step 4 - While pulling the retainer ring backwards, press the valve over the service port, repeat this for both service ports. The question is which ones to buy and which ones are worth your money? Most likely, according to your description, the pulley will spin for a second or two, then stop. In the rare event this happens, you can try removing the trigger and pressing down harder as you replace it again. Do not add Freon to automobiles made prior to 1993 or to one that uses R-12 for refrigerant. Some of the cans have oil in them but that might give you an overcharge of oil leading to compressor failure.
Note: Monitor the refrigerant scale weight to help determine a complete charge. Refrigerant occupies a different amount of space within the can and air conditioning system at different temperatures, causing the gauge to read differently at different times. Putting it to the test With the car running and the air conditioning system powered on, I located the air conditioner's low side connection port. It is definitely on the cheaper side of recharge kits but it will still get the job done. To recharge your you'll need pressurized refrigerant sometimes referred to as freon and a pressure gauge to keep track of how much is in the system. A sealant that has a goo texture can cause a clog.
All vehicles built after 1995 use R134a. Gently tug on the connector to ensure it is properly seated on the fill port. Use the key to start the car and turn the air conditioner on high. First, purchase a charge kit for your car. Mechanics may also perform a black light inspection looking for dye stains that would indicate a leak.
