Is it safe to refill your cars A/C with R-143a if its empty, if you just want it to last for a day?
1998 Ford Escort. My car's A/C has had multiple leaks for a couple years now and has been empty and unused since. I'm driving down to Atlanta, GA, and would like to have at least some A/C for the drive down there. The last time I had the system fixed, it lasted for a week until it all leaked out.
If I have every intention of keeping the car running for another few years, but no intention of ever fixing the A/C system because of how expensive it would be, am I going to do any damage to the car (or the compressor) if I just go and fill the system up with a can of R-134a, maybe with the sealant added in, like you can get from an Autozone?
Added (1). But will I be doing any damage to the car or the AC system itself?
Your choice of R143A is a bad one. First off it is not made for systems like in a car which use low side pressures of 40lbs. This gas works best at 65lbs which would kill your cars engine and compressor. It is also flammable which would not be a good thing if you are involved in a accident. It is also corrosive to the metal parts in the system. R134A would be a much better choice. The sealant with the Freon would be another wise choice. If nothing else when the sealant leaks out it will leave a stain so you can see where the leak is. You might want to also add compressor oil in the system because if the Freon leaks out so does the oil. You replace one without the other and you will kill the compressor real quick.
Yeah, its safe. But look into a permanent fix.
If you want to waste your money.since it will all leak out
Just keep the A/c Switch on off
- Why don't American cars last as long as Japanese cars? My family has owned a Ford Taurus and a Nissan Altima of similar model years. Both cars are still running, but the Taurus has very low mileage (it's a 1999 with only 85,000 miles) and the interior is in horrible condition and the plastics Ford put in have been known for breaking. None of this has happened with the Altima, even though it has more miles. Why?
- How do you determine if your car is under California or Federal emissions if your emissions sticker is gone? I have a 1993 ford taurus 3.8L V6 GL 4dr. Sedan. I need to know if my car is under California or federal emissions. I know you are suppose to have a sticker on your car that tells you but mine was destroyed over time so I really don't know. Is their another way to get this information? How would I find out?
- Starting your engine 4x a day? Is that bad for an old ford ranger? I heard starting to much can put pressure on your engine/starter. Is 4x ok?
- What did you name your mustang or what is your mustangs name? I just bought a 2006!dark blue Ford Mustang and I named it Sally. She's named after the first bar I ever went to which is called Mustang Sally's, and it happen to be my favorite bar. What did you name yours or what is yours named?
