Please take a moment and Register today!In this article, we will go through the conversion from R12 to RA and learn a bit about the specific systems. First, we will go through some standard information.
R12 was the most commonly used refrigerant of all time and it has been used for many applications. The technical or chemical name of R12 is dichlorodifluoromethane. CCI2F2 is its formula, which contains the chemicals that make it up. According to its technical data, the weight per molecule of R12 is about with a boiling point of The molecules inside R12 consist of fluorine and chlorine, which is why it is called chlorofluorocarbon, or CFC for short, an abbreviation that was very common in the s and earlier.
Because of the versatile nature of R12, it quickly became a refrigerant that used in air conditioners, refrigerators and freezers. This refrigerant is used in household appliances because its properties are relatively safe. This refrigerant was neither flammable nor toxic. There was also no risk of the refrigerant being explosive, which is why it was used extensively in household appliances in connection with refrigeration, without posing a risk to the environment or to people.
Furthermore, R12 is an extremely stable compound and remains integrated even under extreme pressures and operating situations. The only problem with R12 was that it would decompose on contact with a flame or fire and become toxic by inhalation. People were advised to quickly switch off all stoves and flame sources in case of leakage and to open all windows so that all the toxic gas could spread in the atmosphere. Soon, after research and studies, scientists concluded that R12, a CFC gas, was harmful to the ozone layer and thus damaged it, which is why alternatives to R12 were chosen.
One alternative to the refrigerant R12 is RA. Soon the R12s were banned in many places. As a result, they were replaced by other refrigerant gases, one of which is RA.
The use of RA prevented damage to the ozone layer. The refrigerant RA is called tetrafluoroethane and is classified as one of the HFC gases from the other refrigerant variants. Today, RA is commonly used in vehicle air conditioning systems, but it can also be used in refrigerators, freezers and other refrigeration equipment similar to R RA is sometimes also used to cool overworked computer systems.
Many organizations believe that RA contributes to global warming. Vehicles manufactured before used R12 for air conditioning. Vehicles older than started using RA instead of R So what if you have a car that was made in or even earlier?
Well, if you have a car that old, you have two options.Before most vehicles came with R12 refrigerant in the air-conditioning system. If your air conditioning is no longer cooling as well as it once did, then chances are you need to recharge the refrigerant in the system.
Recharging an automobile air-conditioning system is rather simple, however, R12 refrigerant is difficult and expensive--you must be a licensed professional to buy it. Instead you can convert an R12 system to an Ra system with a few parts and some basic tools.
Discard any R12 refrigerant still in the system by taking your vehicle to a licensed air-conditioning professional. Releasing R12 directly into the environment is dangerous and punishable by law. Open the engine compartment of your vehicle. Find the high and low side service ports for the R12 air-conditioning system.
Push the low side retrofit Ra fitting over the old fitting and use a wrench to tighten it. Torque the fitting to 20 foot-pounds. Push the high side retrofit Ra fitting over the old fitting and use a wrench to tighten it. Place a retrofit label, showing that you have retrofitted the vehicle for Ra, in an obvious visible spot in your engine compartment.
Ensure that all the valves on your manifold gauges are closed and connect the blue hose to the low side port and the red hose to the high side port. Hook the yellow hose up to a vacuum pump. Start the vacuum pump and open both the high and low valves on the manifold gauges. Allow the pump to run for a minimum of one hour. Close all three valves on the manifold gauges and switch the vacuum pump off.
Connect a can of Ra lubricant to the yellow hose, open the low side valve and allow the vacuum in the system to draw the oil in. Inspect your vehicle's service manual for specific requirement on how much oil to add to the air -onditioning system. Skip this step if the refrigerant you are adding contains oil. Look up the specifics for how much R12 refrigerant the vehicle requires to work at optimum efficiency; you will be adding 10 percent less Ra refrigerant.
Note that underfilling the system can damage the compressor and overfilling the system can cause the seals to leak. Close all valves on the manifold gauges and remove them. Screw the T-valve the top of a can of Ra refrigerant. Start the engine and switch the air conditioning to highest setting. Put a thermometer in the center vent to measure the temperature as you add refrigerant. Connect the T-valve hose to the low side service port. Open the valve and allow the system to draw the refrigerant out of the can--you can feel the can get colder and lighter.
Allow it to drain for five minutes and then check the temperature of the inside air. Continue adding refrigerant until you have added 10 percent less than the maximum system capacity. Check the temperature of the inside air periodically to ensure that the system is holding the charge and that there are no leaks.
Disconnect the T-valve hose from the low pressure side when you are finished.

His latest adventure, Super Mario Odyssey, brings him to the Nintendo Switch, where--once again--Princess Peach has been kidnapped by Bowser, and little ol' Mario needs to save the day.
Unlike the last few Mario games, Odyssey fits into the same gameplay mould as Super Mario 64 and Sunshine. It presents large, open areas and lets players hop, skip, jump, and buttstomp their way around in search of collectibles. Nintendo has put in subtle little gameplay mechanisms that can help you on your quest to get Power Moons--both obvious and hidden.
Some of these systems are explained in-game, but may be easy to miss, while others are left a bit vague. We've put together a collection of tips that'll give you a little leg-up, and get you skipping on your way to rescuing Peach. Check out our full review of Super Mario Odyssey, and for more about the game, check out our roundup article containing features, gameplay videos, and everything you need to know about Super Mario Odyssey.

It currently is back at the Pinkerton Dealership to address the same transmission vibration problem for which it was there two weeks ago. Hopefully when it's returned to me my 2015 Escalade will not have the vibration problem.
