    P0499 - Where's the EVAP solenoid?

    I don't have Quadrasteer - it never came on the Yukon Denali. Only was offered on the Sierra C3, Sierra Denali (03), Silverados and a few Suburbans/Yukons. But, I wanted a truck with Quadrasteer so did some reading on it. Yes, the rear axle is wider which is why you see the rear fender flares...

    P0499 - Where's the EVAP solenoid?

    Wow, tons of great info here - thank you all so much. I figured out my problem and you'll collectively roll eyes at what caused it - BUT if I have to diagnose later down the road, this thread will be a great resource to save. I use this truck to tow with. When I took it to Road Atlanta in early...

    Looks clean! Check for leaks underneath and brake lines for rust.

    6.0L Valley Cover Gasket - How Hard to DIY?

    No, I don't know if I have the oil cooler or if I have a block off there. The truck is 100% stock - so if all Denalis came with the oil cooler, then I have it.

    6.0L Valley Cover Gasket - How Hard to DIY?

    Do the oil cooler lines run anywhere near the filter? Pretty sure mine are original at 10 years and 143k.

    She's changed a lot since I got her!

    It's not my style but damn, definitely a nice improvement from what it was! Had a good chuckle at "Captain Save-a-hoe" :D

    Looking to purchase a Yukon/Suburban/Tahoe... Need advice.

    I'll be the first to champion the Yukon Denali and/or Escalade. Yes, the Cadillac. Hear me out, I tow with mine (6k lbs, ish) and wanted the best vehicle for that use. Don't care about offroad prowess and likely don't need low range, ever. So with that in mind... The Denali and Escalade have...

    Leak Help

    Other places to look (I'm dealing with this now, too) are the valley pan gasket and oil pressure sender gasket. The oil filter housing "plate" can be another source of the leak, but that's on the driver's side. Maybe check your oil cooler lines, assuming you have a cooler? I know the Denalis...

    6.0L Valley Cover Gasket - How Hard to DIY?

    So... it didn't. I did this job because I took the truck in to a local shop as it was leaking a LOT of oil. They claimed I had two leaks - valley pan and oil filter "plate" gasket. I paid them to do the filter plate as they wanted $1400 for the valley pan job. Well, the valley pan was seeping a...

    Where have you guys mounted your backup camera?

    I have a license plate camera, which is "fine" given it cost all of $10 from Amazon. Great to hook up trailers and parallel park in tighter spots. The first camera I purchased could only be mounted offset and thus wasn't centered, which makes it kind of useless. I kept it though, and was...

    P0499 - Where's the EVAP solenoid?

    Managed to replace this and not break that plastic hose and clamp setup. Great success! The CEL comes back on after two ignition cycles though. Sounds like the other Evap solenoid (near the throttle body underhood) can also throw the same code? I figure I ought to replace that one as well...

    6.0L Valley Cover Gasket - How Hard to DIY?

    Got around to doing this job yesterday - check out the sludge on the valley cover! Needed a stepstool to get leverage to remove the cover (it was kinda stuck on thanks to said sludge) so the racecar lent its bumper to the cause: I'm now facing a fun quirk - the drive to work this morning...

    P0499 - Where's the EVAP solenoid?

    Cool. And seems if I do break one, I can use some 5/8 tubing and hose clamps to replace the old hose(s).

    P0499 - Where's the EVAP solenoid?

    Based on the part number that everyone bought when getting the code, I'm replacing the "vent valve solenoid" and elected to get another of the "old style" on the right here: So it sounds like that's above the rear diff. I'll take a look but should be easy to replace. Thanks!
