    I put a new 6.0 in my 13 Tahoe a couple of years back. Exhaust question now.

    Just imagine how much better it'd be running with a tune ...

    Good price for Bilstein 5100s

    Don't leap before you look for a good discount code, or some other incentive that'll lower the price a bit. Won't be easy to find a 5100 set under $500. Couldn't, bought a 4600 set ... still regret it, should've bought the 5100.

    Greetings and Salutations from East Texas.

    Your PPV looks like it has aged very well, nice find! If you're gonna rebuild the front calipers, this is as good a time as any to upgrade to the 2010 Suburban front brake kit: Front caliper brackets Front calipers Front rotors Front pads Feel free to reuse your '06 brake fluid hoses, or upgrade...

    No Go. No Shift. No Gears.

    Engines can work without motor oil for quite some time, all things considered. A transmission without ATF is USELESS. Get ATF back into it. Better yet, soon after you get ATF back into it, drain it and refill it AGAIN, to clean out any issues. Beyond that, can't hurt to analyze old ATF, would...

    At4 6.2 Engine Temp Light

    Motor oil is almost always hotter than coolant, which is almost always hotter than ATF. If ATF is 221F, bet yo @$$ coolant is hotter than 239F, and motor oil is over 257F. This is why I don't want my coolant over 221F if ever at all possible. Only 'vettes have engine temp senSORs which work with...

    Diesel Appropriate?

    GM's Engine Half @$$ was a bad idea, and its implementation was far worse - weak @$$ parts. GM's Cylinder Confusion (SEVENTEEN firing orders!) was a meh idea at best, and once again, its implementation was far worse - weak @$$ parts. Cylinder valve deactivation NEEDS far higher quality parts to...

    Diesel Appropriate?

    Please, for the benefit of those gathered, do expand on this statement? No need to be scared of turbos, if you can avoid them easily enough. Might be difficult to avoid them once the GMT800s & GMT900s age into extinction ...

    Z71 Front End Swap

    Since no one bothered to answer your question, I'm gonna TRY ... Worst case scenario, you may also need to change the hood, POSSIBLY the front fenders? An educated guess based on ... Starting with GMT900s, NYC cabbies / livery chauffeurs would buy or lease Tahoes / Yukons / 'burbans and use as...

    Diesel Appropriate?

    If you need your vehicle to work (or play) HARD, 6.2L. If you only need it to go places and protect yourself from bad weather, 5.3L is ok. Good, do that, even if only by using a plug-in of some sort. (A tune is better bang for the buck, lots more fun, AND the transmission will last longer before...

    Coolant temperature fluctuations normal??

    GM is ... coerced by CAFE MpG scores to do things like ... specifying 5W20 in America, instead of 5W30 nearly everywhere else on the planet ... reducing the bore size and engine size for most pickup trucks and SUVs from 5.7L to 5.3L ... encouraging your transmission to upshift as soon as...

    Coolant temperature fluctuations normal??

    '05 Electrical fan settings. If AC works properly, it lowers coolant temps a wee lil bit, 'cause 'Fan 1' is nearly always on if the AC is on and builds at least 220 psi. 'Fan 1' is 'Low Speed. 'Fan 2' is 'High Speed'. Note how hot the 'High Speed' coolant threshold is. If those temps are too...

    Coolant temperature fluctuations normal??

    1. Only Corvettes get motor oil temp sensors. 2. Even if accelerating at Wide Open Throttle uphill, unless also towing something HEAVY, coolant temp should seldom if ever exceed 221F. I'd check the entire cooling system piece by piece. Feel free start by replacing the coolant reservoir cap...

    '07 6.0L safe max coolant tempurature while towing

    So you're (likely) more aware than the 'average' vehicle owner about how important the pressurized reservoir cap is? Maybe you replace your pressurized cap sooner / more often than, say, sea-level landlubbers? Anything over 221F, I stop driving like an @r$e and start driving like I'm about to...

    DFM disabler released

    1. Why would you even care what 'someone' TRIES to say? 1b. Which 'someone' are you concerned with? 1c. What if they try to say something you don't like, but they fail? 1d. In case we don't make it to '2', this is why I'd prefer the Range - quick connect, quick disconnect ... quick disavowal 2...

    DFM disabler released

    1stly, I recommend getting tuned. However, I know that is getting not only more expensive, but logistically more difficult. Pretty soon, even when you buy something brand new, it won't really be yours, which pisses me off. 2ndly, I recommend disabling cylinder (valve, really) deactivation...

    DFM disabler released

    You'd be shocked at how much you learn from tuning mid-90s LT1s asking every question your tuner'll allow when he's tuning your GMT932. Many of you who think you're against engine / transmission tuning, would be for it if you understood what they're capable of. (An answer to a question no one...

    Ran out of gas! 2008 LTZ

    If you intend to keep your vehicle for 'the long haul', seriously consider buying a replacement fuel pump now. They won't get any cheaper.

    DFM disabler released

    DFCO does NOT deactivate cylinders - or if you prefer, DFCO does not deactivate valves. During DFCO (and powertrain braking), valves open and close normally, like it's been done since the 50s, or whatevar. It's merely FUEL that is not being used during DFCO. I suppose DFCO could be combined...

    Thoughts on purchasing a higher-mileage Duramax?

    Any halfway decent turbodiesel that fails to exceed 300,000 miles is an indictment of its previous operators. If the motor oil was changed every 5000 miles, good. If more often than that, so much the better. If you address maintenance items slightly sooner than recommended, 300,000 miles should...

    Brake noise

    If it only squeaks that one time, I would not worry about it. If you insist on being worried about it, next question: If you back INTO your driveway next time, and then HEAD out of your driveway, does your front driver side brake still squeak then? EDIT @ 1106pm: I was not being facetious, I...

    6.2l engine tick

    Thoughts, my @r$e. Buy a quart of 0W30 and a quart of 5W30. Put both in the freezer overnight. Pull them out of the freezer, crack them both open, pour them out simultaneously. OW30 will pour out quicker and smoother than 5W30. Meaningless once the ambient temp is over 41F, but it makes a...

    Bilstein 4600 review on a Z71 Tahoe

    In NYC, there are no H2s in any junkyards. There are a few GMT921 PPVs left at JFK & LGA airports, maybe I'll risk getting shot in the @r$e, read the VIN off one of those so a parts mungqi can give me the right stuff. Heck: anybody got a VIN off a (GMT800 or GMT900) Tahoe PPV? Hopefully I made...

    6.2l engine tick

    The tick MIGHT fade out sooner if you use 0W30 instead of 5W30.

    Low Blinker Fluid?

    Whenever you go to a car wash, it's supposed to be part of the car wash process! Also whenever you drive in the rain.
