    2010 DENALI 6.2 Motor "Seized"

    Was just looking at steam vents and wondering if I should put the old one back in or upgrade? What kit did you use?

    I feel a clunk from a stop.

    Amen to that, felt like I’d been in a prize fight afterwards. But I won with a lot of patience and busted knuckles!

    I feel a clunk from a stop.

    My 2011 Avalanche had similar “clunk” and it was the drivers side motor mount. Common problem with GM trucks\SUV’s and a relatively easy fix.

    Engine Startup Procedure rebuilt 2009 6.2l Denali (Rookie Question)

    This forum is great! Thank you all for your input, advice, and recommendations. I have a referral to a local tuner that I’m going to work with before cranking this thing up. It’s my first time working with an LS engine and I don’t want to screw it up. My last engine build\swap was in a ’73...

    Engine/Transmission swap help

    For what it’s worth, I just removed the engine and transmission from my 2009 Yukon Denali (AWD) as one unit. The engine was seized and there wasn’t anyway to disconnect the flex plate from the torque converter. It was a beast of a job and I ended up having to pull the heads inside of the...

    Engine Startup Procedure rebuilt 2009 6.2l Denali (Rookie Question)

    The 2009 Truck didn't come with AFM\DOD so the computer the existing computer doesn't have it. I did the kit on the rebuilt engine, i.e. lifters, cam, valley cover.

    Engine Startup Procedure rebuilt 2009 6.2l Denali (Rookie Question)

    Picked up a 2009 Yukon Denali AWD with a seized engine recently from a friend that wanted to scrap it. I happened to have a freshly built 6.2l from a 2013 Yukon XL that I was going to put in my 2011 Avalanche, but decided to use it for the Yukon instead. The rebuilt 6.2 has new bearings...

    Rack and Pinion Tubing

    I managed to crush the hydraulic tubing on my 2009 Yukon rack and pinion while removing the engine. Anybody know the part number or a source for just the tubing and fittings? Or am I stuck replacing the whole unit?
