    Minimum psi of 20 and usually 35-45 above 2000 rpm and your fine.

    2011 Tahoe LTZ Shocks

    Google it and it will tell you. Air shocks in the back and there will be codes on the sticker like 6vb, etc.... If you look at the front shocks there should be electrical connectors. Z55 is the smooth ride option.

    Towing setup confusion

    ZW7 is a smooth ride shock so no unless someone added air shocks.

    Towing setup confusion

    You seem to have the right coolers. Try towing with a light load and see what happens. I would flush your radiator and check your water pump. I had an LS water pump crap out on me.

    GM better come up with something better than their current engine lineups

    I am in full disagreement on your statement. I think the bad parts are due to poor QA and cost cutting. Not due to focus. GM needs these engines at the most profitable plants they have. That and 3$ will get u a coffee at some coffee shops. Not pikin a fight, just giving u my opinion.

    Low Battery Start Engine

    Your battery is overcharging.

    Torque, meaty rubbers and pavement plus jumping off the line and hard cornering equals rogue tires. No injuries. Felt it coming and was pulling over.

    Thats why spacers are a bad idea....

    [HELP!] Have you ever heard this metal on metal noise?

    How many think the GMT 900 series is the best TAHOE/YUKON yet?

    As a bump to the OE thread I will add this: The GMT 800 is the MOST comfortable seats in ANY SUV i had. The 900 drove great- still does- not pretty but a great riding vehicle.

    GM better come up with something better than their current engine lineups

    The SBC came out in 55' as a 265/283 and in 97' the LS came out. Now the LT with its Direct Inject has basically taken the ICE about as far as it can in its NA form without putting $ 1000's into turbos etc. Our Hammer and Sickle Greenies want us to collect cow farts and live off the...

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

    It will run smoother. I bought my 2012 Denali it had 134 k on it and clearly had OE plugs. It ran fine but the idle was smoother. Its amazing how these Iridium plugs last. The platinum pugs are basically done by 80k miles.

    2013 Tahoe oil pressure question

    I use the Wix 57045 filter. has a 12-15 psi bypass.
  19. avalonandl

    Low oil pressure

    Just as an FYI I use the Wix 57045 on my 2012 6.2 Denali. This has a DIFFERENT size thread but a 12-15 psi bypass so it always has that min. PSI.

    Suburban vs Yukon xl interior.

    Higher quality trim in Denali for sure.

    2012 Suburban LTZ Callaway

    Thats a sweet ride. I would love a SC but will probably stay with the NA 6.2. I deal with the pitted chrome wheels on mine. I replaced one of my wheels (it was just a touch out of round).

    Aux Fuel Tank 2013 GMC Yukon XL 2500

    Yeah I had a 2004 Avalanche 2500 and the aux tank was 11 gallons. It had the 8.1 so it was ALWAYS thirsty but pulled a 31 ft Cat no problem.
