Is it possible for your truck to 'burp' itself?  Let me explain, my truck, an 06 GMC Sierra with 5.3, had a leak in the radiator and was overheating,so I changed it.  OK it's still overheating, so then I changed out the water pump,still overheating. Changed the  thermostat and I cleaned out the heater core, still overheating! so I did a compression test on it and it failed.  you know the blue turned green. Head gasket. so I parked it until I can afford to fix it. so I parked it until I could afford to fix it.  it was about 2 months I guess, that she sat. maybe that's that And I hopped in it today, she  fired right up. I was taking her to the garage, expecting it to over heat before i hit the end of my street and ive been driving her for 2 days and no overheating.  Hmmmm? Please explain.

Maybe it just needed a break?

 

Give it a week, problems may creep back up or maybe weather in Mesa has been cooler this week than normal. Sometimes the issues fix themselves and we never know what the fix was. Pretty much like hitting the steering wheel or dash in certain situations. 

 

Apologies for the randomness of the post, haha

Well, I guess I'm a bit ahead of you.  Replaced the heat sensor which activates the fans. I replaced the thermostat twice, replaced the water pump, replaced the valves & surfaced the heads because the #4 cylinder was down to 85psi dry test. no water in the oil & was told it was likely venting into the water jacket.  Valves were iffy & truck has 200k+. Thinking the head gasket was the issue & everything was opened up, might as well while we're here & I don't want to come back for a while. none of these solved my problem. Still overheated with in one tenth of a mile. Had the radiator tested & was told it was 85% good. So what else are you gonna do? Dropped in a new Radiator. Still overheating. I'm in  over $2300. My buddy comes down from his off-grid mountain homestead & pulls the coolant reservoir cap and shows me that the lower "O ring" is chipped. explains that it is compromising the atmosphere so that the boiling point is lower & therefore pushing coolant out the overflow while driving. This explains why we never saw any coolant leaks while parked. At O'Reilly's it cost $11. 

 

That was in January & here we are in May & the truck is overheating again with the reservoir low. Will l be paying too much by ordering it from factory?........

 

I actually was hoping to find out what the operating temps are for the cooling fans but thanks to your question I will opt for the new cap. After all, it did work for a while.....

 

But your question was about self burping. I would not count on it but welcome to Chevy Mystery Theater. Mine sat for months before it got running again, but then it was running & the coolant is going somewhere... Please let us know if you find resolution.

      Missing thrust bearing? And oil selection

      By Atlas · Posted

      Stan, this thread is specifically related to the Duramax 3.0, in the 2019-2026 powertrain subforum. If you'd like to talk about your other vehicles and offer anecdotal stories about them, please consider starting a thread in forum that pertains to your truck, or the other vehicles/ Off-Topic section if they are not a GM truck.

      Video processing module location

      By twgraham · Posted

      Can someone tell me where the video processing module is in a 2023 Silverado? I'm getting conflicting results that it's in the front passenger area or the rear passenger area behind the seat.

      Yes I agree, its what amounts to free advertising to let people know about his UOA testing company, and not that there is anything wrong with that but certainly that is a motivator for putting out videos about the science of oil as well as other topics such as oil and air filtration etc. The interesting part I found with his last video is not only the physics behind the reason for the varying wear due to a diesels working torque range causing more bearing load and that higher viscosity oil is of benefit, it was also that the chemistry behind the GM Dexos 0W-20 and the Mobil Dexos licensed 0W-20 are far enough apart that its showing up with a difference in wear even though the two oils are matched in viscosity and in that comparison viscosity was not having the finger pointed at it.    There are a few youtubers out there or one anyway that I have watched a bit of who has gone through the pains of accessing various countries manuals for a certain engine platform and while in the US/Canada it may say use 0W-20 or what have you for some Toyota product, in some other countries it sings a very different tune for the very same engine with the typical traditional oil viscosity/ambient temperature charts to help choose which oil viscosity is correct for the conditions the vehicle will be used in and in some cases its taken an engine in a US manual that states only use 0W-20 as per warranty coverage and yet that same engine in certain other countries may have up to a 15W-40 etc oil option that meets the spec. Another words the guy who is driving through Death Valley or Phoenix and south weather at 120f is often being fed a line of bs by the US system that has forced vehicle companies to restrict the warranty to a specific low viscosity oil for anterior reasons as well as the long drain interval suggestions.    Thankfully youtube is free ( yet anyway ) for viewers to sift through information and of course comes with the good and the bad ( truth and lies ) and we can choose to turn off/not watch what a person finds is bs or just not interested in the topic.

      No doubt... But, as someone who doesn't pay for his services, but who has provided a few views/clicks on his Youtube platform, the data around the Mobil oil testing I think does have some value including to "freeloaders" like me.   A lot of what he's doing is likely showing the OE's work in their oil selection, something that many of us had kind of assumed was true all along, a good balance of both excellent protection and efficiency.

      Lake Speed is drumming up business for his company just by being in the spot-light so he has a vested interest in stoking the 0W-20 fire.  IMO
