I cant get over the load on battery from dash, lights, HVAC system on these Chevies.  Not to mention starter draw from constant on/off useless system that costs more in batteries and starters than pennies of saved gas!!

Anyone notice the heating/ventilation system changing door position 5 minutes after shutting off? Symphony of noises, doors closing5 mins after key off. Guessing its for recirc door to shut, preventing any rodents from coming in/ any thoughts? Another power drain!

 

I often travel, and leave truck parked a week or 2.  I'll install a 55watt solar on dash form now on. Heck, when it's 20 below, it wont hurt battery! $60 US for a folding one might save me one day. At minus 30 , you need all the power you can get!

 

Front cam installed last week works real slick. My wife hit a trailer hitch bar, sticking out a foot from of some wreck Ford pickup. You just cant see these things, like short posts of steel or marker pins. The cam is mounted at base of license and sees these hazards. This "Wolfbox 900" cam is very clear, and mounts right over rear view mirror. It's a dash cam and rear view, but i installed the cam low in front. Dash cam is invaluable when your cut off by a Ford that lost it's steering wheel :)  I installed a cigarette lighter plug on right side fuse box, with a switch to kill all power. This Cam is working well and is very clear, easy to install . $175 US

 

Found out those grooves in our roofs are useless, not roof rack mounts available. Found a rack on Ebay, similar to GM or Thule roof racks offered by GM for $800 US

Cost me $180 US, coming from Turkey. Hey, they make good drones there..:) I need a rack for my paddle boards and Hobie Kayak when pulling a travel trailer. Will post on it's quality after it arrives.

Not necessary.

You would be surprised how easy these trucks start at -30F.

My 22 LTZ w/5.3 sat for a month last winter in MN. Never started it until a -23F below morning. I remote started it from my couch. It popped right off. Little power steering pump squeal though.

Yes, Minnesota gets exactly the crappy cold weather we get here south of Ottawa. We're ok the first year, but 2-3 years and that battery is toast. My refresh has that huge display, that does a light show on start up. 

Do you notice the heater vents closing a few minutes after shut down? What the heck is that for? At minus 30, those doors have to swing open and closed. They can snap from being frozen. Happens in Dodge...thousands to replace those vent doors!

Previous 2010s GM vehicles I have had have been notorious for mildew/mold buildup on the condenser and putting out a foul smell when you start the truck the next day if you didn't run the heater to dry it out before turning the truck off. I had to go get the dealer to activate the afterblower function to dry out the condenser after parking. These newer trucks probably do all these things partly to help dry out the condenser to prevent the smell.

I think the sounds you are hearing a couple of minutes after shutting off the truck is the Anti lock brake "aliveness test". I read a post on here months ago from an engineer who worked on this system at GM. This is a self test of all the electronics, sensors, actuators, switches etc. in the ABS system.

 

I will be watching for that Ford that lost its steering wheel so I don't get cut off!

What roof rack or mounting hardware did you get? Got a picture of it installed?

Tell us you don't know what you are talking about without actually telling us.

 

First, the starters aren't your off the shelf regular starter, they are much more robust and designed to last just as long as a regular starter even with all the start and stops. Things can be over engineered for certain tasks and these are just that. Just checked on Rockauto, a Genuine GM starter for a 2014 5.3 Silverado is $132 and that is without start stop. For a 2020 5.3 which I assume has start stop (correct me if I am wrong) is $157. So even being more robust (the power is much higher on the 2020) price difference is negligible. 

 

Two, batteries are designed as such, now they aren't massively more powerful and there are more systems drawing on it but the start stop system plays a minimal role in a possible shorter life. But again, these are designed from the get-go to handle many start and stops each trip. 

 

Third, in terms of fuel saving, it's much more than pennies. On the low end let's say 3% savings, that is 9 cents per $3.00 gallon of gas. Over one year of say 15,000 miles you spend $2,250 on gas (15,000 miles / 20mpg = 750 gallons x $3.00). At a 3% savings that is $67.50 in one year (a nice dinner at say Texas Roadhouse) and at the higher end at 8% that is $180 per year, or a nice high end steak dinner probably excluding drinks. Add that up over 5 years and they easily pay for a starter or new battery (from $337.50 to $900 over 5 years). I don't know about you but the finance side of me isn't going to just piss money away because I have some complex. 

 

Savings overall depends on usage, if you drive a ton of city, it will save more. If you don't, well it won't save as much but it will be used much less often and last longer in your eyes (though really, they shouldn't last any shorter than without the technology and a regular starter and battery). Plus, bigger engines tend to save more fuel as noted in the below article saving in upwards of 10% on a V8 Jaguar. Now in hot weather with AC the system saves much less but still more than just idling (closer to 3%).

Clip on type roof rack from ebay was counterfeit. Fell off if you whacked it. GM one is very similar and clips on. Gave up and got bed rack instead from Amazon.

    • I will be doing that for sure, but I need to solve who has/ where I can find a bidirectional scan tool that will support OBD 1.5. I'm kicking myself because I ebay'ed a Snap On MT2500 that I didn't think I'd ever need anymore. D'oh!! I'd rather not buy another, so I'll contact a few local shops to see if they have one and how much they'd want to do the procedure. I'd rather have the ability to do it myself... I wish there was a modern tool that could do it all, but I'd have no idea what to buy.   The theory with the pulled timing is that it mimics a rich condition. The delayed spark causes incomplete burn and the O2 sensor picks up low oxygen levels. That's interpreted as a rich condition so the PCM pulls fuel and that shows up in the deeply negative fuel trims.
    • An ultra wealthy man had the most beautiful daughter. But, there was a problem. Everything she touched would melt in her hands. No matter what, Metal, Wood, Stone. Anything she touched would melt. She could not feed herself. Because of this, men were afraid of her. Nobody would dare marry her. Her father was despaired. What could he do to help his daughter? He consulted doctors, scientists and anybody who could solve this problem. Finally one of them said, "If your daughter touches one thing that does not melt in her hands, she will be cured." He was overjoyed and came up with a plan. The next day, he held a competition. Any man who could bring his daughter an object that would not melt in her hands would be given billions of dollars to marry her. Three extremely intelligent and handsome young men took up the challenge. The first brought a very heavy steel rod, But alas, when the she touched it, it completely melted in a matter of seconds. He sadly went away. The second brought a beautiful diamond, knowing diamonds were one of the hardest substance in the world and would not melt. But alas, once she held it in her hand, it melted. He too was sent away disappointed. So now, there was one left He was very nervous & sweating. He approached the daughter & said, “put your hand in my pants pocket and feel what is in there." She did exactly what he asked. She felt something very hard. She held it in her hand, squeezing it as hard as she could. It did not melt & remained extremely hard. Her father was overjoyed. Everybody was overjoyed. She was finally cured. Nothing never, ever melted in her hand again. They married and they both lived happily ever after, raising a wonderful family. Question: What was in the the groom’s pants pocket??? Answer below ↓ M&Ms of course! They melt in your mouth, not in your hand. What on earth were you thinking?
    • There's a bunch of tea leaves that you've read, but in any case the delayed timing is unusual. Not sure how that relates to the rich at idle vs. 'normal' while driving.   If you're in this deep, might be worth investigating, and re-learning the sensor. What have you got to lose? Plus, it properly fixes the timing cover leak.
    • The only problem I have seen this cause is longer crank times. 
    • Injector is being sent off today for rebuild and I estimate I'll have it back in 10 days or so.   It may not be the injector...of course...now that I've torn down the intake again. But, let's rule out the injector and replace those spider legs that have been almost rubbed through.   The truck has always had negative timing and I'm reading "normal" timing at warm idle should be +16 or so. I'm negative 16 to 25 or more, and it's always been like that since I bought it.   A light turned on upstairs last night in the old noggin. Rare, I know...   This will be wild, if it turns out to be the cause!   In 2001, according to the old service documentation, the muffler was replaced. Why? I have no idea, it wouldn't have been rusted through by then. But they did a crappy job.   In 2019, another shop replaced it and noted the prior install was poorly done on the work order. "Exhaust system vibrates on crossmember". Except...I guess they just left it be? I believe the husband, the couple who were original owners, had passed by then. Maybe she said it's just not worth it to have the exhaust system fixed and declined repairs. Very few miles were driven between 2019 and 2025.   The exhaust system vibrates heavily on the crossmember and you can feel it and REALLY hear it, even today. Not always, but at idle, it gets going pretty good sometimes.   What if....   ....What if that's enough to trigger one or both of the knock sensors? Could it be tricking the sensors into sensing knock, so it's pulling timing aggressively? Pulling timing heavily means it's firing after the piston reaches full height which means incomplete burn which means the O2 sensor is sensing a rich condition, which means I've been chasing my tail, and what I thought was an inconsequential problem (janky exhaust) has been THE issue for this truck for 25 solid years?   That would be wild. Maybe it IS wild.   The service documentation thereafter, for years, shows visits for rough idle, replacing O2's, replacing the cat, replacing plugs and wires, a misfire condition, like they could never solve the issue. The injector has been replaced 4 times in 80k miles, that's just crazy.   The secondary theory....   The engine has clearly had a leak at the front seal for a very long time (the greasy trench...). I think the truck changed hands quickly ~2025 because there's Napa receipts from someone I don't recognize in the ownership history. They apparently replaced the timing cover seal, and they did a terrible job. There's RTV smeared all over and the leak I had reduced to a weep by snugging the front oil pan bolts is now a leak again.   HOWEVER....I read about replacing the crankshaft position sensor. Any time the ckp sensor is disturbed or timing cover is removed, the truck requires relearning, and that can only be done through a bi-directional scan tool. Skippy with the RTV probably didn't do the relearn procedure is my guess. His scan tool is lost in a pile of RTV goo somewhere.   So, it's very possible the sensor has been disturbed and the truck is just running on the old learn data but not setting a code for anything. The distributor has since been replaced and so has the camshaft position sensor, so all bets are off for that thing.   In the theme of one step forward, two steps back, I returned the accumulator for the AC. The gal I've been working with at O'Really's has been great. She refunded it under manufacturer's defect and we compared it to the replacement I ordered, and sure enough, the replacement is machined very differently (and a gauge actually fits on it!).   Got it home, installed it, started vacuuming it down.... and I couldn't get good vacuum.   The high side service port, where I replaced the old GM ball valve suspecting that was a source of the previous leak....well, I've clearly exposed whatever pre-existing crack in the line where the service port is welded, and made it much worse. Blessing in disguise? Except there goes another $25, now I'm waiting for a replacement AC line.   In 10-ish days ALL the parts will be here. Rebuilt injector, new exhaust system, new cat, new high pressure AC line.   Oh, did I mention the squeaking ISN'T coming from the AC pump? The truck still squeaks when started, and there were words after I started it with the new AC pump installed. But, there was more to replacing the AC pump for just a squeak. A truck with good working AC is something of value, for the comfort alone.   I've ordered a new harmonic balancer because, 30 years is a good run for one of those. Rule it out. The squeak may be something more sinister, though. I'm worried about that ckp sensor and if it was shimmed correctly, or if the timing set was installed correctly. The squeak may be coming from UNDER the timing cover.   At this point, once I get it put back together, I'm thinking I'll take a 50 mile victory lap and then promptly put it up for sale. This truck is cursed. Betty, from beyond the grave, doesn't want anyone messing with her Blazer. Or maybe she's getting revenge for 30 years of shop visits with that thing.
