We are trying really really hard to help, and I am sorry you feel we are insulting you. I myself am done giving advice, since you are not using any of it. John and I have said the same thing over and over. And there was no answer to whether you purged the air from the hoses. You are getting upset b...

"how i do bleed it without vacuuming the whole system and does having a little air in system hurt it?" Yes a little air hurts. You can't really do what you asked, which is why we suggested that you have the system evacuated and start from scratch. You seem inexperienced at this. When you ...

i had the ac on max and circulation on with windows down, air feels cool but not ice cold if its makes sense. How do you set it at 1500 rpm? I see article says i might have air in my system but im not sure. If so how i do bleed it without vacuuming the whole system and does having a little air in sy...

As first post stated my 2013 mustang gt i have owned since new, its been over 9 years and ac was never serviced, refrigerant must be low by now. Just because the car is nine years old and the A/C was never serviced during that time doesn't mean that the refrigerant must necessarily be low. It's cer...

sorry double post

Ignore the charts. They only serve to confuse IMHO. For instance, at 40 PSI, the evaporator would be around 45 degrees, resulting in center-vent air of more than 50 degrees--hardly enough cooling to provide a comfortable cabin. At 27 PSI, which is what you measured initially, the evaporator would b...

You are repeating yourself. Your original pressure readings were within the range of normal. Why did you add more freon? Now your high side is too high, suggesting as John says overcharged, or contaminated with air. Pressures should be read with engine at 1800 RPM for all cars. Max cool, max fan, w...

How were you testing the system with your Manifold Gauge Set hooked up--engine at 1,800 RPM, windows open, compressor running, blower on high? If so, the pressures measured by your MGS before you added any refrigerant look pretty good (ambient temperature not mentioned). With a high-side of 350 PSI...

but my problem is i emptied almost 2 can my low pressure gauge didnt change only high pressure gauge got increased from 200 to 350psi.

Hi im in the process of topping off my ac refrigerant on my 2013 mustang gt which never had ac serviced. My ac is still cool but not cold and compressor would cycle on and off often. I decided to do this myself and watched quite a few youtube videos and got myself a yellow jacket 42006 series manifo...
