    4-corner steam port setup

    Anyone have a suggestion for a 4-corner steam port kit? I'm looking for something that will fit my 6.2L in stock configuration. I searched and found a thread discussing this, and one fellow mentioned that his 2000 Sierra 5.3 had a factory 4-corner setup. Does anyone know about that or whether...

    The Falcon died...

    Wife went to pass a doofus driving a semi who pulled out in front of her. She was half-way around him after engaging the Hyperdrive pedal when she heard a strange sound from the engine compartment. Dash lights came on, and the steering got heavy, so she decided to pull over. Fortunately, she...

    Burned spark plugs

    Hey, All, I changed out my O2 sensors, and decided to check my plugs while I was at it. I installed these plugs less than 40k miles ago. At the time of purchase, the Delco 41-110 was recommended, and I puchased them from Amazon (yes, I know, now). I bought Delco 41-162 from O'Reilly or...

    Cat temps?

    Driving up the hill the other day on a moderate, 3 mile-long grade, A/C on, 105* air temps, and no trailer, my converters hit ~1800*. What temps are considered too high in the converters? Thanks.

    Engine cooling fan relays

    Good morning! Just replaced my 5 blade/7 blade cooling fans with TYC 622210 7/9 assembly. 200k miles on the clock, and I'm leaning toward replacing the relays, as well. Should I replace the relays due to the mileage and wear and tear, or replace as needed? Thanks.

    CV joint boot material

    Hey, All. The outer cv boot on the driver's side front axle has come loose at some point. No idea how long ago, so with all the dust I have I'm going to replace the entire shaft assembly. I'm looking at the NAPA units, and they are showing two boot material options: 1) OEM neoprene, and 2)...

    Which is the better front control arm?

    Which is better: Mevotech CTX series or Moog CK series? Or, is there something better? I'm not altering the suspension from stock, and I'm running OEM 20" wheels. I plan on doing upper and lower as well as the tie rods. Thanks. ETA: I might as well get suggestions for the tie rods, also...

    New tire time coming soon

    It's about time for new tires. We just had our first good winter storm with rain, frozen rain, sleet, hail, snow, and now mud, all of which showed me that I might need to buy them sooner than later. I was leaning toward mild, all terrain tires with the mountain snowflake designation, but some...

    Patching up the 6.2

    Hey, all, wife's Denali dropped a valve seat. We've had the vehicle for a year, so the model is still new to me, and I'm looking for suggestions on better quality parts; mainly gaskets and head bolts. Saving up for a new engine and trans, so I don't need to go crazy, yet. Thanks.

    New to the forum

    Hi, all, been a lurker for about a year now since buying my wife a 2009 Yukon XL Denali. She calls it her "Millennium Falcon". We're replacing her 2002 Suburban Z71 with it, and the difference between the two is night and day, thus the name. This thing takes off like a rocket ship. We've had...
