Default Re: Milage in Colorado

Are you running your A/C all or most of the time? That sound you are reffering to is your fan clutch, it comes on to bring down the engine temps, and will come on quite a bit more when the A/C is on. When the A/C and or fan clutch is on it will suck down a decent amount of power. Enough to make a noticable difference, and will knock your MPG too.
