    2010 Tahoe loses all electrical power momentarily

    Yes, like Fless said, I think the door locks cycle when the power is restored. It happens so fast that its difficult to say what is happening. To Mikes point about the ignition switch, I had thought of that, so with the car running I wiggled the key around for a while thinking maybe something...

    2010 Tahoe loses all electrical power momentarily

    Here is something I have never experienced before, and I'm hoping someone here has, or has some recommendations: I have a 2010 Tahoe with about 260,000 miles on it. I put in a new engine and had the transmission rebuilt about 40,000 miles ago. At that time I also removed and re-loomed the...

    Cooling fan wiring colors / advice in wiring aftermarket fans

    This did the trick. In case anyone ever has this question and comes across this thread, the light blue and grey wires were the hot ones. Thanks all, and especially Doubelieve!

    Cooling fan wiring colors / advice in wiring aftermarket fans

    I am in the process of installing an Entropy Radiator which came with two larger more powerful fans in an integrated sort of shroud. Unfortunately, they use a Metronix 280 connector which is not the same as the factory harness connector. I have the parts to make my own Metronix 280 connectors...

    EGR/VVT Sys and EVAP Sys Monitors Incomplete

    This is probably what I need. Far more detailed then the other sources I have seen, and I think the devil is probably in those details. I will try this in the morning and report back. Thank you!

    EGR/VVT Sys and EVAP Sys Monitors Incomplete

    It is time for my state inspection and they hook up an OBDII scanner to the car during that inspection. I have EGR/VVT Sys Incomplete and EVAP Sys Incomplete in the I/M monitors. I am allowed to have one or the other monitor incomplete, but not both. I changed the battery in the car shortly...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    I used one that I got off of Ebay. I pulled the rear interior out to sound deaden, so routing the wires was easy, and I even ran them into the hatch through the factory rubber conduit. Got power from one of the reverse lights. I have heard that some Tahoes may be plug and play with the...

    What did you do to your NNBS GMT900 Tahoe/Yukon Today?

    Finally got my backup camera installed. And added about 100 pounds of sound deadening material to the back hatch, cargo area floor, and the area over the rear wheel wells. The camera is great, and I can definitely tell the difference with the sound and vibration while going down the road.

    Need help finding front brake hardline

    Well, disaster has struck. The mount to block bolts on the driver side loosened up and allowed the header to contact one f the brake hardlines that run along the frame rails on that side. Its a little hard to see in the picture, but you can see the staining on the header where the fluid got...

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    Thanks Rocket Man! She's running great although, as with most projects like this, I am already looking at doing some more things to the Tahoe. Specifically, I think I need to upgrade the cooling system. I think an aftermarket radiator and fan set up is next. It also needs tires, and I think...

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    I got the front main seal fixed, and also (finally) tracked down and fixed the transmission line leak. I don't think it'll ever be truly done, but the Tahoe is now completely drive-able, and a real blast on the road. I still have a list of things in my head that I'd like to do to it in the...

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    Its time for another update... I installed a Morosso Catch Can that is marketed specifically for these vehicles (really just means that it came with a bracket that lines up with some factory bolt holes), and also installed a valve in the line going from the valve cover to the intake. No more...

    Transmission Cooler Mount Options in a Tahoe

    Shimmyt - Did you figure out where to mount it? I recently put a Derale in my 2010 Tahoe, and I think its the same model. If you are still in need of mounting location ideas, I will try to get some pictures tomorrow. I'd try to describe it but I need to go look at the car before I can even...

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    Ok, after looking the car over today more closely, there is definitely oil in the exhaust. There is a coolant leak too, which I believe is coming from the rear steam crossover. I'm probably going to pull the intake, and maybe just block off the rear steam crossover. Whatever the case, I am...

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    No wideband. It could possibly be rich as it is on an initial tune. But I thought it would be a darker color smoke if it were rich? I'll get a video in the morning in light so the color of the smoke is more clear.

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    Yes, it smokes when warmed up. In fact in that video it was at 210 on the gauge. I'm going to check it in the morning, but if anything I'd say it smoked less when cold. I never thought of it being the cam. Thats interesting. I HOPE that's not the issue as I really don't want to change the...

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    Today I got the rear main swapped and fitted, with a high degree of confidence that its correct this time (hope I don't jinx myself). I got the transmission back in, and then tinkered with the temperature for a while. It turned out that the fans actually were working. I'm not sure how I...

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    Well, the purpose of the Milodon oil pan is that the stock one was filthy and my wife said "you can't put that on the new engine" and I said "I'm going to clean it first" and then she gave me a certain look and I went inside to buy a new, clean, oil pan. And since I was getting a new one...

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    Hhmmm, I'll verify that my tune file looks like it was copied properly.

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    At long last, I was able to work on the Tahoe today! I recently started a new job, and I've been living in a hotel since the end of March, and away from home, so obviously unable to do any work. Today I installed the new head unit, and got the wires run most of the way to the back for the rear...

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    Yes, the wiring for the fans is stock. I'll have to look into that.

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    The RPM comes down to about 800 and it is really lopey. I was using HPTuners to monitor fan settings and other parameters.

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    There may be a better way to do this on the forum without resorting to Youtube, but here is a link to the video of the first start if anyone is interested and has 54 seconds to kill. I think I'll title it "The thrill of victory before the agony of a leaking rear main seal."

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    Dang it, I forgot about the air-conditioning. I'm going to give this a try tomorrow. I don't think the fans got unhooked, but I think it would be prudent to retrace the harness for them tomorrow. As for the tune...I know that this is a possibility, but I don't know enough to know what is...

    Engine Swap to stroked 6.0 (408) and general vehicle refurbishment

    When your post popped up I went out and ran my hands around both valve covers. Dry, unfortunately. I also felt around the starter and while the snout is wet, the top seems dry. Unfortunately I don't think I am going to get that lucky. Earlier this evening I also felt around the oil pressure...
