car is running cold now. All is well. I used the yellow and green seal and everything seems to be going well so far. The only kind of weird thing... intermittently i will hear a whooshing noise from the fan area for about 5 seconds or so and then it will turn off... and then on again and off. The fan is consistently blowing fine. I am wondering if this is something with the expansions valve and adding and removing refrigerant to the evap?
