    Since I have installed my K/N cold air intake it has caused my IAT to go up nearing 200* which causes my truck to run badly and not start sometimes.

    2008 Denali 6.2 Roaring sound while accelerating

    I later figured out that my passenger side motor mount was broken and anytime under a load it would roar and then quiet down once it shifts to high gear. The motor mount was the culprit!

    2008 Denali 6.2 Roaring sound while accelerating

    No. I thought It was a defect to the compressor. I warranty it out and it still made this noise.

    Cooling fans??? Well shouldn’t they make this noise when I don’t have the hvac system on?

    2008 Denali 6.2 Roaring sound while accelerating

    It only does it when driving. It’s the 2nd new compressor on the truck due to this. I’m confuse. I’ll see if I can get a video to upload.

    2008 Denali 6.2 Roaring sound while accelerating

    So I have a 2008 Denali and when the HVAC power button is on it roars when accelerating until it hits high gear and goes away. This only happens when HVAC button is on, if it's off it accelerates with no noise at all. Need all the help I can get.
