Mazda Repair: 97 Millenia S A/C Noise, mazda millenia s, mazda millenia

Question
I have a 97 Mazda Millenia S in Dallas, Texas = very hot! Recently I can hear "gurgling" noise when the kicks in at park. It goes away when the car is moving. The A/c still cold and able to keep the car at 74C in the 100C Dallas heat. I wonder I need to do something now to keep it developes into bigger and more expensive problem down the road. Thank you in advance for your assistance in this matter.

Answer
Hi Gabriel thanks for asking
i have heard this one before, but the last one i did wasnt that seriouse but there are 1 of two things that you could be hearing. When the AC system is on the rasdiator will get hotter then normal, and you may be hearing, the antifreeze bubbling over in the overflow tank or the rad. it is also possible that you are hearing the freon equalizing in the system. On AC system there are two sides to it, when the pump is on it brings the high side of the system up to about 3-- pounds per square inch, and on the low side it will run about 40 pounds per square inch. when the pupp turns off wich happens frequantly, you could be hearing the two sides of the system equaling out to the same pressure, that will guve you that weird noise,
Good luck
