    Need recommendation on 9006 low beam bulb replacement for 97 Tahoe

    Looking for a recommended 9006 low beam halogen headlight bulb to swap into my 97 Tahoe . I actually don't recall ever changing out the OEM bulbs in 25 years believe it or not and light projection down the road at night is just not very good anymore. I did repolish the lenses so I don't...

    No heat while car is warming up

    I did look at what I thought were those T's going into the firewall. I will look more closely at them tomorrow. I do recall 10 or so years ago they were replaced as they were leaking at the time. Looking back through my maintenance notes I found that we have replaced the water pump at 95,000...

    Would I see coolant on the ground from that? Can I visually see the T's in the engine bay?

    No heat while car is warming up

    With 286,000 miles on the engine, I am leaning toward the theory presented of an internal coolant leak. There is no external leak that I can see or smell. In fact now I wonder if I needed a water pump as that was GMC's diagnosis back in September, that the weep holes on the pump had signs of...

    No heat while car is warming up

    Before start up and cold I added about 1/2 gal Dex-Cool (50/50) up to the Full Line on the reservoir, started the engine and after about 30 seconds it had drawn down the coolant in the reservoir well below the Full Line. I shut off the engine and added the remainder of the 1 gal Dex-Cool and...

    No heat while car is warming up

    I welcome all suggestions. I believe I will take the advice of adding coolant and go with the theory that air was in the system from the Sept water pump replacement. Then I will keep an eye on the level routinely to see if it declines. I would welcome recommendations on coolant to add assuming...

    Checked coolant level. That is it. Very low. Must be losing coolant somewhere as the water pump was replaced by GMC in September and coolant topped off at that time.

    No heat while car is warming up

    Back again with 2005 Tahoe issues. When we are warming up the car before driving during these cold mornings in NC, the heater is blowing cold air even though the temp gauge shows the engine is warm. Not until we start driving does warm air start flowing from the vents. In addition to this the...

    2005 Tahoe/Fuel filling problem

    Again, great insight. After all the work GMC did to address this issue described earlier, we started having some issues with stalling and rough running plus our Tighten Gas Cap message continued when first starting up. Two codes were picked up, one indicating a malfunctioning fuel tank pressure...

    2005 Tahoe/Fuel filling problem

    Turns out the charcoal canister was filled with fuel so it was replaced as well as the valve solenoid. They credited me for the purge valve replacement so all 3 are now new. We'll know if this solved the issue when we fill up next. No more "Tighten Gas Cap" message so at least that is a positive.

    2005 Tahoe/Fuel filling problem

    yes it does scream blockage. When we picked up the Tahoe after the purge valve was replaced we still say the Tighten Gas Cap message. It is back at GMC today for further diagnosis. I called them and alerted them to the smoking gun likely being a clogged charcoal canister and/or faulty...

    This has to be the problem! Thanks!

    2005 Tahoe/Fuel filling problem

    Great feedback, thanks. Our 05 Tahoe is back @ GMC and they will try to isolate the problem. Part # 12581282 was changed. We also get the "Tighten Fuel Cap" error message which seems unusual as it is tight and was replaced by GMC 1 yr ago on an earlier service. This message only appeared after...

    2005 Tahoe/Fuel filling problem

    To me this seems like the logical culprit. Is it easy to visually see this vent behind the fuel fill?

    Yes, the tank has not been dropped and no other work has been done.
