    Oil Capacity Question/Verification

    Quite well aware to FULLY seat dipstick due to the O-rings. It was fully inserted. I actually tried multiple times as well as waited hours before checking again to make sure oil had fully drained back into the pan. What I was looking for is NOT what the oil capacity Spec as this is listed...

    Oil Capacity Question/Verification

    I am aware of prior dipstick and dipstick tube issue with other manufactures, however, this does not appear to be a dipstick or dipstick tube issue. I verified the oil level from the factory fill before the oil change. The oil was at the top of the hash marks on the dipstick with the factory fill.

    Oil Capacity Question/Verification

    Oil was checked on level ground. 8 quarts added after oil change had NO oil on the dipstick hash marks. Yes, I also realize with this dipstick it is tricky to determine the oil level with fresh, clean oil. As mentioned, I checked it before the oil change to see where the oil level was on the...

    Oil Capacity Question/Verification

    Checked the oil before the first drain and the oil level was to the top of the x/hash marks on the dipstick. From my first use of this dipstick, it appears it really only will detect 1 quart of oil. If oil is not shown on the dipstick it appears that the engine is at least 1 qt low, but it does...

    DFM disabler released

    Reply from Range after I noticed issues with the Readiness Monitors on the Range 007. [email protected] Tue, Nov 19, 2:58 PM (13 days ago) to me That is going to be normal. You would have to disconnect the module and do a drive cycle for the systems to show ready.

    2 nd engine failure, waiting since Oct 17/2024

    What were your Oil Change Intervals? Do you go by the OCI? I have concerns on these engines that fuel dilution of the oil is a problem, so shorter OCI's might be wise? Understand that you may not need to worry about this as you may get out from under this vehicle. I plan on changing oil every...

    Oil Capacity Question/Verification

    Antonm, your 6.2 may take 8 quarts, but mine took 9 quarts. I appreciate you thinking I lost count of how many quarts I put in or misfigured something along the way, but I did neither. I had 2 5 quart containers and I used 1 quart to flush the cranckcase while the drain plug was still out and...

    DFM disabler released

    I would say there is an improvement in acceleration and transmission smoothness, or at least not having the engine hunting and turning cyclinders back on during tip in throttle and acceleration. This then equates to less or no transmission hunting as well. I am still not sure about the "0"...

    Oil Capacity Question/Verification

    I know this issue may have been tossed around a bit, but I beleive there is something with the stated oil capacity for these engine. Vehicle - 2024 Yukon Denali XL 6.2l gas engine. Everything I read indicated that the engine oil capacity is 8 qts with filter. Change initial oil at 500 miles...

    DFM disabler released

    While the Range 007 is not as easy to plug in and out as and OBDII adapter, it is still not very hard to install and remote. On my 2024 Yukon with 22" wheels, I did not need to remove the drivers side wheel, just like 6 small screws for the inner fender liner and pull it out of the way. If you...

    2024 Z71 mpg .. can it be this bad?

    Keep in mind while the engine is idling and the vehicle is not moving you are geting exactly 0 MPG! The more remote starting is used and the more time is spent at stop lights, stop signs, drive thrus and kid drop off and pick up with the engine running, this will KILL the Average MPG with a lot...

    DFM disabler released

    Just so everyone is aware, and Range did not have this info on their website in the description, when the Range 007 device is plugged in the Evap and O2 Sensor Emission Readiness Monitors will not become Ready. So if you live in an area that requires Emission Testing, you will need to remove the...

    No codes, power loss

    Blackhawk. Can you get me 2 Logs, I will be able to get an idea if the catalytic converters are a problem by looking at the Post Cat O2 sensor behavior. I may not be able to tell you they are clogged, but I can tell you I think they are not clogged. This could save you money and your wife...

    No codes, power loss

    Blackhawk, You can graph out the Ignition timing and see what is going on if the timing is being pulled too much for some reason. I would probably limit OBDFusion to maybe 5-8 PID's to monitor to give a better response time for the timing changes. This can be very helpful, I used a different...

    What is This sound from my engine?

    You seem to leave out quite a few details when making statements. These trucks due also have lifter problem, but they are usually not going to be fixed with the miracle unicorn juice. If the oil changes have been stretched out too far then the lifters wear as I recall. Both myself an a number...

    No codes, power loss

    From the first glance, I do not see anything that stands out and screams "problem". But I also understand the problem is somewhat intermittent mostly at highway speeds. A few items to note: 1. Engine coolant temperature looks good overall. 2. MAF so far on initial look appears normal. 3...

    No codes, power loss

    Simple thing, although you are not the current end user, it to just Uncheck the Lat & Long settings under Log Setup, Select Items to Log, GPS and then uncheck Latitude and Longitude. However, sometimes Altitude can at times be useful if the vehicle is being operated in an area with rapidly...

    No codes, power loss

    OCTech is one of the best for App support. I personally suggest people turn of the Lat & Long function in the App so your location will not be identified. It might have been a problem where the Lat & Long was listed under the GPS Items to Log and the GPS was not turned on and this was a...

    What is This sound from my engine?

    This is the biggest Goat Rope/Cat Herding exercise I have ever seen. If the rear bolt is broken, I guarantee there is an exhaust tick until the engine warms up slightly. Ask me how I know! Put a freaking clamp in the thing and move forward. There is NO WAY a shop can tell if there is "air...

    What is This sound from my engine?

    I think you are mis-understanding. I do not think your vehicle has the Active Braking option that has 2 rear brake supply lines. This was a option on many trucks, but may have been standard on the Denali's. Looking at your picture, it appears you have a 5 port ABS valve, not a 6 port ABS valve...

    HELP! '05 Denali Brake line routing

    Many of the Denali's have dual brake lines to the rear of the vehicle because they have individual rear brake ABS not a single brake line for a common ABS for the rear wheels, this is why most of the Denali's have 6 port ABS valves.

    What is This sound from my engine?

    Tonyrodz Thanks for your comments, I think your case is not atypical. I know a few people this happened to as well and they all seemed to be caught totally off guard and were just plain lucky that nothing catastrophic occurred. Its not like this is current news, but some people either have not...

    Battery dead after a couple days...

    Start with the OnStar unit as 1999hoe above said. I agree 100% this is likely to culprit. Pull the Entertainment fuse, forget what number the fuse is, but I recall it is in the under hood fuse box.

    What is This sound from my engine?

    The NAPA guy is not driving the truck, easy for him to say. But take his word and choose to do nothing. Good luck when you have your family in the vehicle and you need to stop in a hurry. It is possible for BOTH lines to burst at the same time and they do. You should ask him about the rear...
