I see. You do not believe that I should be referred to as a mechanic, because mechanics cant ask other mechanic questions about a car, or they must not be a mechanic, right? I had an unusual temperature sensor response on the gauges and I asked the people in this forum for suggestions. Maybe someone has seen the problem before, and had fixed it. Whats the problem with that?

Everything was working normally, and then the problem started showing up, but it was hit and miss. I burped the system, and it seemed to solve the problem, so I posted the issue as solved. After posting the problem as solved, a few days later the problem returned! I burped the system again, and the problem went away. Then it came back. After running the engine, the system was holding good pressure, so I don't have a water leak anywhere allowing air into the system. Would you like to know what the problem turned out to be? Actually, I should ask you that. Your the mechanic and i'm just a loser idiot. So tell me, what was causing the temperature gauge issue? How is the air getting into the system?

 

(no, its not a blown head gasket).

You can call yourself a mechanic all you want. But I would bet my last dollar you don't do this professionally in a shop working on customer vehicles on a day to day basis at any reputable shop. You spread wrong info and its upsetting. I own an automotive repair biz, and everyday I deal with people who come in defensive and misinformed because joe blow on the internet fed them a bunch of BS. I can fix some pipes but I don't call myself a plumber. It is fine for a mechanic to ask another mechanic a question about a vehicle, happens daily in my shop. But thats how I know, if you were actually doing this professionally, you would ask someone else you work with, not a forum of truck owners that probably 99% of them are not mechanics. Sorry if I embarrassed you, I wasn't trying to be rude or combative but like I said it pisses me off when people spread blatantly wrong and sometimes dangerous information. That is not what a professional does.

Issue: Temperature gauge works intermittently, with strange symptoms.

 

Details:

 

Essentially useless..

When you start it up cold, it will go up a tiny bit but wont go over 160.

Sometimes it works normally on startup, and reads properly.

Out of the blue it can start or stop working.

Sometimes you turn the key on, and it reads normally but after you start the engine it quickly drops to 160 and stays there.

Works normally for days, stops working for days.

Faulty temp sensor code came up once, but didn't come back after clearing the codes.

Vehicle may be running rich, smell of fuel in the exhaust sometimes.

 

Checked the electrical connector

Replaced the temp sensor (front left of the motor, by the exhaust manifold).

Tried banging on the instrument cluster

No coolant leaks or other cooling system issues.

 

Has a block heated installed.

 

 

As a mechanic, I HATE driving around without knowing my engine temp. Please throw out some ideas. Running out of options, and I don't want to go with an aftermarket gauge setup.

 

According to the original post (see above), you were chasing an electrical issue with the gauge. At no time did you mention that the cooling system had be opened up and had air introduced. As a mechanic, you should have known that this was the first thing to check AND stated that the symptoms began after the broken connector and engine block heater installation.

 

With gauge issues on these trucks, the stepper motors are a known issue and a good place to start looking.

      Transmission Temperature Hitting 220s

      By Grumpy Bear · Posted

      After I wrote that reply I went for a ride. 85 F out. So trans started at 85 F and it shifted the same as it did an hour latter at 168 F. I've never actually recorded the to cold to shift point but it is under 32 F before they start hanging on to a lower gear or leaving the converter unlocked. Both intended to heat fluid.    Yes, brake or bake. Absolutely.      Your welcome. True research ended decades ago. Field trials are still in play.    There is a thing called oxidation onset temperature. This is the heat related oxidation not the O2 exposure kind. For mineral oil that starts at 140 F. So what happens after 140 F? Each 20 F cuts fluid life in half! Does using a Full Synthetic improve that? Yes! By how much? Depends on the base oil type and a few other factors. But enough to notice. Some esters are even higher. There are even synergies between types the will raise it higher than any one component is alone.    Then there is "Hindered" oils. Antioxidant additives. Hindered Polyol Esters can sit at 500 F for years in a turbine.   When a blender brags his oil will 'take 500 F" in service he doesn't specify for how long. Water will dance on a 500 F hot plate for several seconds. @newdude put up a chart showing the relationship between fluid temperature and it's life in an automatic transmission. Here's a version of that chart for Group III based oils. These temperatures are those in the pan as observed as 'normal'. that is you drive as you do for as long as you do under what load you ask of it and whatever that temperature is this graph applies to. Flash temperatures of a few minutes isn't what his means.    Note that fluids held at a constant 240 F have a service life of only 20K miles. 220 F explains the factory exchange limit, eh? My equipment I keep under 180 F and I'm good if the cooler will hold it as low as 140 F. But that's me.

      Im in the same boat. Carlink adapter comes tomorrow and dev account is in process. Would you he able to send the new instructions my way also? Question, do you have to change code and republish app everytime developer updates? Thanks for your assistance, truly the only thing i cant stand about my truck is the carplay limitation

      Weight limit in bed

      By rav3 · Posted

      And Google AI says......... Yes, your truck can technically handle it, but you will be right at or near its maximum limit. A 2016 Chevrolet Silverado 1500 High Country with a 6.5-foot bed has a maximum payload capacity of approximately 1,770 pounds.Weight RealitiesLoad weight: Half a cord of dry hardwood weighs roughly 1,100 to 1,500 pounds depending on the wood type (like oak or hickory).Payload limit: Payload includes the weight of the wood, you, any passengers, and a full tank of gas.The math: If you weigh 200 pounds and have a full tank of gas, a 1,500-pound load of wood puts you right at that 1,770-pound ceiling.Safety TipsCheck the yellow and white sticker on your driver-side door jamb for your truck's exact payload number, as high-end luxury trims with extra features have slightly lower capacities than basic trucks.Expect the rear end to sag noticeably.Drive carefully, avoid sudden turns or stops, and keep speeds low if you have to travel a distance.
