    P0499 - Where's the EVAP solenoid?

    Got a CEL and discovered it's for P0499, the EVAP solenoid. I can't seem to find a definitive answer as to where the part is located on the Tahoe/Suburban/Yukon. Seems like it can be in a few different places on the pickups. I ordered the new part ($20 from Amazon, thank you Prime shipping)...

    6.0L Valley Cover Gasket - How Hard to DIY?

    05 Denali - Power steering loses assist at slow speeds when hot

    I've done a bunch of Google-fu and am not finding a ton of conclusive information, so was hoping some of you could provide insight. 2005 Yukon Denali, 134k. I had the steering box replaced a few months ago due to excessive slop and leaking. All was well for a few thousand miles, and now I...

    Me and "Big Blue" - New to the forum, '05 Denali

    Figured I'd register and make an intro post, since I do have a few questions about my new daily driver, and likely will continue to have more as I pile on the miles. Just picked up a 2005 Yukon Denali right after New Years' Day. It's Blue Green Crystal (the only color I wanted) with about...
