    03 Tahoe vs 05 Tahoe Gauge Cluster Interchangeability

    A forked plastic trim tool is ideal for pulling the needles, but be gentle. Be sure to rotate the needles fully counterclockwise until you feel the resting spot of the stepper motor, then put a small piece of blue painter's tape on the gauge face underneath the tip of the needle. Mark the...

    Evap issue question 09 yukon 5.3?

    You can run it. All you'll get is the CEL for the emissions issue. Sounds like the evap lines might need to be blown out.

    ^^This^^ And this is just a wild guess, but these clusters can get what's called "silver migration" on the circuit board. The cluster can be disassembled (like when changing stepper motors or backlighting) and the circuit board cleaned. I'm not saying that's what causes this, but it's a...

    2002 yukon Z71 thermostat question

    Your thermostat temp is an opening temp, and the engine will run hotter than that, depending on the efficiency of the cooling system. 200°-210° F is normal.

    Long term and short term fuel trims intake leak, low idle, improving fuel mileage. Mpg

    Did you reset the LTFTs when the injectors were replaced? Those values are learned and could be carried over from the prior situation. Eventually they should get closer to what the STFTs run. The STFTs show it slightly adding some fuel, well within ideal, so there's that. Those are...

    Both wiring harness cut to stock stereo unit 2004 chevy tahoe. Please help!!

    Moved this thread from Supporting Vendors. It might help for clarity if you correct your speech-to-text results. ;) If you don't find the wiring colors, visit a U-pull yard and cut a pigtail off of a like vehicle. Splice like colors.

    Alternator going bad?

    If you powered up (110v) your charger when the voltage went up, that's the charging voltage. But if your charger reads voltage without AC, then I don't know what to say. Short trips don't allow for the charging system to completely fill the battery, so if your wife's trips aren't long enough...

    07+ Brake upgrade on a 00-06 NBS, is it worth it?

    The OE calipers ARE two-pot, and the overall diameter of the rotor is a hair under 12". The NBS rotors are right at 13" overall, with larger pads. Get out the measuring stick to see what you have.

    Problem going backwards

    Yes, kudos to @Coolman1987us! The caliper bracket bolts should have blue loctite on them when reinstalled and should be torqued appropriately. Haven't we had two or three others like this lately? Got a pandemic of loose caliper bolts? ;)

    Where should I start?

    Before you start throwing parts at it, do some diagnostics. Multiple new parts without the science to back it up tends to introduce too many variables and some frustrating tail-chasing. Low battery voltage can cause some of these issues, and short-tripping really hurts the charge and can cause...

    Probably need new O2 sensors?

    Yes. Upstream is pre-cat and reports to the PCM so it can adjust fuel trims.

    Battery Drain

    The "sensor" is the whole latch, so bite the bullet and replace the latch. Mine did the same, and it's a wear item on vehicles this old with a lot of use of the driver's door.
