How to convert an R12 compressor to a R134a?
R12 to R134a Conversion steps. The first step is first to make sure that the AC system is empty. Discharge and make sure to recycle it properly. Make sure your AC compressor is in good shape, otherwise replace it. Flush your current system entirely of R12 without leaving any traces of the R12 in it.
What can the R134a air conditioner be used for?
The R134A is now commonly used in the air conditioning systems in vehicles, but it can also be used in fridges, freezers and other coolers similar to the applications of the R12. The R134A is sometimes also used for cooling overclocked computer systems.
Which is the low side of the R134a?
Remember, there are two sides to the chart; we have the low and the high. Therefore in a normal R134a, the low-pressure side is 90 degrees or less, and the PSI should be close to 30. Why Is my Low Side AC Pressure High?
What should the PSI be on a R134a?
The pressure for an ordinarily operating R134a is between 22 and 57 pounds per square inch (PSI). Remember, there are two sides to the chart; we have the low and the high. Therefore in a normal R134a, the low-pressure side is 90 degrees or less, and the PSI should be close to 30. Having gone through all the above details, you are still wondering,
Why does my AC compressor not turn on?
Sometimes, when you want to recharge your AC, your compressor will not turn on. This is because the PCM senses low pressure and it will not let the compressor turn on. Watch this video to see how to bypass the relay switch and engage the compressor clutch.
Why did I need to replace my air conditioner compressor?
But considering the age of my ’88 IROC-Z, the desiccant was probably not removing moisture from the system very efficiently, so I replaced it. Replacement compressors also typically come dry, with no oil-making conversions easier.
How old is a third generation air conditioner?
Third generation F-body cars are anywhere from 8 to 17 years old now, and that usually means your air conditioning system is either wasted or is going south. It could be a number of things: bad compressor, a blown o-ring, or worse, the dreaded slow leak that no repair shop can find.
What happens when you replace an AC compressor?
You also might hear a lot of noise, such as chattering bearings or a squealing belt (if the compressor is seized up). The compressor’s clutch also may not engage and will just stay cycled off all the time. While this may seem like a death sentence—especially in the height of summer—replacing AC compressors isn’t the most complicated task.
Why is the oil coming out of my a / C compressor?
This happens as an under-lubricated seal around the compressor’s crankshaft dries up and develops a leak that allows for refrigerant and/or oil to escape. Not so much of a problem years ago when you could bring your car to any service station and get R12 topped off for 99 cents; but those days are gone like the old Freon.
When do you need a new air conditioner compressor?
It is also common for the seals in the AC compressor to go bad. The compressor may start leaking refrigerant and/or the AC oil. If the seals no longer hold, you will need a new compressor, as the seals cannot be replaced. A compressor may also fail if there is sludge or debris in the air conditioning system.
When to replace the AC compressor in a GMC Truck?
Since it was under warrenty, they replaced it, and this time flushed the whole system and even replaced some kind of valve w/ a coil on it in the rear A/C system. Drove it 24,000 miles after that w/ no issues, until the day i traded her in.

What kind of oil do you use for a R-1234yf compressor?
Newer vehicles with R-1234yf A/C systems require a special 1234yf compressor oil specified by the vehicle manufacturer. General Motors recommends GM lubricants only (PAG-PSD1 #19260643 for 2013/14 Cadillac XTS, and PAG-ND12 #19299051 for 2013 Cadillac ATS).
How much Oil can you put in an A / C compressor?
A/C Compressor Oil Capacities If you are replacing a compressor or other A/C system component, it is important to replace any compressor oil that has been lost when parts are changed. The total system oil capacity for many late model passenger car A/C systems is only about 4 ounces (120 ml).
How much refrigerant is in a Toyota Camry?

When to replace R12 freon with R134a Freon?
This next step is important because it is time to recharge the system. The rule of thumb is that the replacement R134A Freon is about 80% of the R-12 charge. If you charge the same amount as originally installed the system will not function properly. Next you’ll want to run an AC performance test on your new retrofitted air conditioning system.
When did cars start using R12 instead of R134a?
Many organizations believe that R134A contributes to global warming. Vehicles manufactured before 1994 used R12 for air conditioning. Vehicles older than 1994 started using R134A instead of R12. So what if you have a car that was made in 1994 or even earlier?
