BlackOut V8

Posted June 24, 2010

My ac belt squeeks when my AC is not on. I did a recharge and put in 0.8kg or 1.8g's of refrigerant and did it on a viper recharge machine. I opened the oil valve for a fraction of a second and probably put in 50ml of oil. My ac blows cold and is great but when i turn it on the truck is very underpowered and makes a big bang noise when it engages. I just want to know what i can do to prevent the intermediate squeel when my AC is not on. I have just replaced the belt along with the recharge and cleaned the pulleys with brake cleaner.

  It is acceptable. The temp range is really to just make sure the t-stat is open and fluid is circulating fully. (Even easier is to just put in 6 qts.)

  Hi Hopefully someone has already encountered this and figured out the fix. I get in the truck and start the engine: -the seat belt light will be on. -when I fasten the belt, the light will start blinking. -after ~1 minute (driving or sitting still) the light will go off, the 'Fasten Seat Belt' will illuminate on the dash and the system will beep a few times. The 'Fasten Seat Belt' will go off after a few seconds. -after ~3 minutes, same thing with the 'Fasten Seat Belt' on the dash and a few beeps again. 'Fasten Seat Belt' goes back off. Nothing else happens again. -This happens whether or not the passenger belt is buckled. I've taken compressed air and blown out both buckle latches - no help. Ideas?
