Help, can't get air bubbles out of coolant system
So ever since I bought the car, when I turn on the AC, I get a high-pitched gurgling noise behind the left vent.
Searching the forums, figured it was some air in the coolant system -> so I bought some coolant at autozone, put the car nose-first on my driveway incline and let it run for 15 minutes with the heat at full blast, the AC compressor off. I occasionally would go out there for a few minutes and hold the RPM at about 2000-2500 to get the engine workin. After that, I topped off the coolant in the reservoir.
After this method, I take it for a spin with the AC on and no annoying noises!!! For a day or so.... but it always returns. Sometimes when it's acting up and I'm at a red light or something, I'll turn off the AC, crank up the heat for a minute or two and then go back to the AC. Even this little effort will usually make the noise disappear for a lil while.
How can I permanently solve this issue?!?
