    2008 Tahoe Service Charging System

    I’m not 100% positive on this but the pulsating could be the alternator. I have noticed a pulsating too. I think the only way to verify is to put a new factory alternator on your vehicle to see if it rectifies the issue. There never seems to be better equipment than factory unless you go with a...

    Rearend upgrade

    I am building an 03 Tahoe 4wd and It is going to be a family/hauling vehicle. I would really like to upgrade it to 8 lug, but I don’t see a way possible for the front hubs so I am at least going to upgrade the rear axle to a bigger 6lug 12/14 bolt. Is there a factory rearend that will bolt in?

    2008 Tahoe Service Charging System

    I did get my issue resolved. I had to replace my alternator but I have found that the alternator on my Tahoe fluctuates depending on load on the system and if the headlights are on/off. I don’t have the automatic light sensor installed right now so my headlights are always on unless I manually...

    Alternative Gas Cap

    I have gone over the system and I have replaced the purge valve. thinking that was the problem. I have tried a new gas cap and that didn't fix it. I pulled the evap canister and removed the charcoal because I was having an issue when filling up at the gas station. I noticed that I have one line...

    Alternative Gas Cap

    So.... Is there a different cap that works better than the factory style? I'm not a fan of the breakaway type cap. Do the newer vehicles have to run that type for the fuel system to function properly?

    Alternative Gas Cap

    I have had my issues with the EVAP/Fuel tank and I still get a tighten gas cap at around a 1/4 tank. I still have to take the cap off and reinstall but it clears and everything is good. This leads to my question. I have the yellow e85 cap and I honestly will never run e85. Is there an...

    Tighten Gas Cap/Stall

    It was pressure. I still haven't resolved the problem completely. I haven't had anymore stalling or hard start issues... However, I did get my first p0455 code a couple of days ago. I have replaced the gas cap and still got the code, but not the tighten gas Cap. So last night I reinstalled the...

    New Headlight Housing

    thanks for the feedback. I will try a new search. I'm not sure why I was only getting stock housings. I was getting all kinds of options for the other models, but none of them were specific to the tahoe/burbans

    New Headlight Housing

    Are there any options for the 07-14 tahoes besides stock for headlight housings? I have searched and found different styles for yukons, silverados, and sierras but nothing for the tahoe.

    Tighten Gas Cap/Stall

    Update: It has been 9 days since I started this post. I checked the gas cap and it seemed to be fine. I have filled the tahoe up a few times, and I've had no issues until this morning when the tighten gas cap displayed on the dash. I pulled over and left the tahoe running to check the gas cap...

    Tighten Gas Cap/Stall

    It will be a couple of days before I can post a scan. I have to set up my PID's and graphs in my HPtuners if I share any info like that with you. You also mentioned an evap code. Does the 08 system show an SES light for the evap system? I ask because it never gave me any warning before it acted...

    Tighten Gas Cap/Stall

    Didn't really know where to post this. Move it if it needs to be somewhere more specific. Here is the problem: I have be getting intermittent Tighten Gas Cap displays on the dash and I would pull over to re-tighten the gas cap. It would clear and I would go on with my drive. This morning...

    2008 Tahoe Upper dash repair/replace

    If it’s a cap then the original dash must be really bad. In the video I tried to share… I can literally move the dash (with my hand and very little effort) at the gauge cluster because there are no screws or tabs securing it to the structure that holds the electronics gauges/radio/climate...

    2008 Tahoe Upper dash repair/replace

    It is a 2008. It looks like it could be a possible cap. However whoever did the so called repair/cap removed the sensor for the automatic headlights that sticks through the dash at the base of the windshield and left it in the glove box. That is one of the reasons for the post. I will work on...

    2008 Tahoe Upper dash repair/replace

    Have any of you removed the top of your dash? If so is it very difficult? I assume it will take some time but it is something I am going to have to do. The previous owner or someone that serviced the vehicle used clear silicone/calk to (I’m guessing) re install the top of the dash because they...

    Replacement Weather Stripping

    AHHHHH HAAAAAA Thanks Mike! I was searching for the relief valve by the wrong description. I kept getting the rear cab vent that goes under the back glass for the trucks.

    Replacement Weather Stripping

    I have been searching but can't get anything definitive. I have checked rockauto, Amazon, Ebay, and the only thing that continuously comes up on my searches are rolls of weather stripping that is considered universal. I haven't been able to find a parts diagram either. I know there has to be...

    Replacement Weather Stripping

    I am searching for weather stripping for the liftgate on my 08 tahoe, and also for the vent behind the left rear corner panel above the taillight housing. Is there a place to order from or do I need to go to the dealer for such pieces? I need to find something because I have a leak somewhere...

    2008 Tahoe New to me but have some issues

    Mine broke on the top of the valence on the driver side. I am going to replace the whole system to update it like I have the other parts. I thought about replacing just the bad spots but the lines are glued to the T fittings. I finally got the struts, sway bar links, and some new tires. I have...

    2008 Tahoe New to me but have some issues

    Did you use new T fittings and change your nozzles? My driver side tube broke off at the valance under the windshield so I can either re attach to the wiper arm or change the nozzles.

    2008 Tahoe New to me but have some issues

    I know this isn’t engine/drivetrain related but I have had good feed back from you all. I have to replace the washer fluid tubing due to dry rot and need a full system. Has anyone had to do this? If so did you buy a kit or build yourself?

    2008 Tahoe New to me but have some issues

    Thanks for the positive outlook. Its hard going from one setup to another and seeing all of the different changes. Going from an 03 that shows steady voltage and oil pressure too the 08 has been nerve racking. Especially because of me having mechanical issues from the start. everytime I see...

    2008 Tahoe New to me but have some issues

    I disabled the DOD/AFM with my HPTuners so it won't be coming back on. I did it to save the lifters and hopefully save the valvetrain. The reason for blocking the bypass is to help with oil pressure. It was suggested by a friend of mine that has been building LS motors since the early 2000's

    2008 Tahoe New to me but have some issues

    The driver side interior door handle has broken plastic so I will check all of the switches in it first and go from there. As for this whole journey.... I didn't want to buy this 08, but I was in a tough spot with the 03 going down. It lost either a rod bearing or a lifter. I had already started...
