No matter what jack is used, it's a good plan to have boards/blocks on hand incase the location for changing the wheel happens to be soft....

Diesel exhaust fluid is a 'Reductant'. (used in the process of reducing NOx emissions) Powertrain warranty for dmax is 5 yr/100,000. Emission is less -- but length seems to depend on the component. Some emissions items (and depending on model year) have been given 'enhanced' warranty. I don't know it yours will be covered.

That's why I ordered one. (standard bed, that is). Don't have a TPW yet

Sounds like OP used the spot the manual suggests. Rear Position - 1500 Models 5. If the flat tire is on the rear, position the jack under the rear axle about 5 cm (2 in) inboard of the shock absorber bracket.

This isn't 2020 vs 2020, but it's 6.6 vs 6.6. Doing same job, lots of 55 mph commuting. Not me operating it. Stole the post from another site. I went to a gas burner last year and here are the results. I have traded Chevrolet pickups every 14 to 16 months for several years. All have been Duramax engines until last year and I went with the 6.6 gas. I am basing my figures on 36,000 miles a year which is my average. I commute to work about 40 miles each way on rural 2 lane highways, 55 mph speed limit. All of the diesels have averaged over 36,000, 18.3 to 18.4 mpg. I drive a 3/4 ton for carrying capacity as the bed is always loaded with my tool/ service skid which weighs around 2000#. I tow maybe 10% of the time and mostly short trips hauling round bales. The gas 6.6 has gotten 15.3 mpg under the same conditions. So diesel used 1956 gallons while the gas has used 2353 gallons. There was more info about fuel costs, etc, but fuel prices being a local thing I didn't copy that part.

Congrats on the new ride! Will the garage door close?

Does the front black one light up? With the daytime running lights or do headlights have to be on?

Every been in a garage with the lights on and tried to look at something in the dark outside? Turn off the garage lights, the eyes adjust some, and the visibility outside the garage improves. Same problem with dash and radio that is too bright. Eyes adjust to the the inside level and that makes the headlights seem worse than they are. Especially as the eyes get a little older. Back in the day, the dash didn't have many light sources, they weren't near as bright...and most of them could be turned completely off.

Maybe we will finally be able to turn it down/off independent of the dash-gauge backlighting.

The emissions system is NOT set up the same way as the 6.6, (I'm not familiar with the 2.8, except to that it uses an engine oil not the same as the 6.6, and not the same as the 3.0) Exhaust Aftertreatment System The exhaust aftertreatment system is designed to reduce the levels of hydrocarbons (HC), carbon monoxide (CO), oxides of nitrogen (NOx), and particulate matter (PM) pollutants remaining in the engine’s exhaust gases before they exit via the vehicle’s exhaust tailpipe. NOx is controlled by a Selective Catalytic Reduction (SCR) converter combined with precise injections of Diesel Exhaust Fluid (DEF), while PM is controlled by a diesel particulate filter (DPF). To reduce packaging volume and manufacturing cost, the SCR catalyst on the DPF is coated to form an SCR-coated DPF, or a Selective Catalytic Reduction on Filter (SCRoF). The close coupled DOC along with the SCR on Filter are integrated into one assembly. In the DPF, particulate matter consisting of extremely small particles of carbon remaining after combustion are removed from the exhaust gas by the large surface area of the DPF. DEF is injected into the exhaust gases prior to entering the SCRoF stage. Within the SCRoF, NOx is converted to nitrogen (N2), carbon dioxide (CO2), and water vapor (H20) through a catalytic reduction fueled by the injected DEF. The exhaust aftertreatment system components (Fig. 5) include: Exhaust temperature sensor DEF injector mounting flange Exhaust pressure differential sensor pipe Exhaust pressure differential sensor pipe EGR flange NOx catalytic converter assembly Particulate matter boss Exhaust back pressure valve Fig. 5

Some have posted that the limiter set by factory based on the tires it was born with. I can't verify, but...police tahoe probably has different speed rating tires than crew cab 1/2 ton..

FWIW, mines an '18 sierra 2500 ( I don't think trim level changes the cables) Cable, bolt and spacer look just like the pics dplarson posted

Yes. 'Bump' the key and the computer takes over. Been that way for a bunch of years.

https://gm-techlink.com/?p=13560 Silverado HD/Sierra HD Brake Squeal August 24, 2020 Some 2020 Silverado 2500/3500 and Sierra 2500/3500 models may have a brake squeal condition caused by the low scorch friction material used on the original brake pads. New brake pads are available that have a high scorch friction material to reduce the potential for noise. Replace the front and rear brake pads with the new pads. TIP: Each brake pad has an Inner or Outer label to indicate where it should be installed. (Fig. 6) Fig. 6 If the pads are replaced and the squeal sound continues, check the orientation of the pads. If the inboard and outboard designation on the pads indicate the pads are installed in the wrong location, the squeal sound may persist. Keep in mind that only the left side of the truck has the wear sensors, which are mounted on the inner pad. (Fig. 7) Fig. 7 Refer to Bulletin #20-NA-020 for additional information and part numbers.

Should be somewhere 2 gal def per 100 gal fuel.

I find that the vehicle paint colour can have a significant difference in the appearance of chrome. Chrome that blends in on one colour can appear over-done on another. Same sort of effect with black trim.

21, then a 22.

Are you following the numbers and procedure in the back of the owners manual? in the U.S., call 1-800-462-8782. Is this the one you tried? We encourage you to call the toll-free number in order to give your inquiry prompt attention. Have the following information available to give the Customer Assistance representative: . Vehicle Identification Number (VIN). This is available from the vehicle registration or title, or the plate at the top left of the instrument panel and visible through the windshield. . Dealership name and location. . Vehicle delivery date and present mileage. When contacting GMC, remember that your concern will likely be resolved at a dealer's facility. That is why we suggest following Step One first.

50 miles seems kinda quick, but I wonder if it is an oil issue and if the additives in the wrong oil are not suitable for the diesel emissions and have poisoned the SCR/DOC/DPF. Be sure to post what you learn! Edit to ask: Was this the first oil change? If there was earlier change(s) were they at the same garage?

Good summary. Some situations it's great, and sometimes it's annoying. We have 2020 Acadia with it. It's another tool in the kit. When I drive it sometimes I use adaptive, sometimes I use regular cruise -- and sometimes I just drive. We've ordered a 2021 1500 and it will have it. I guess that means we like it well enough on the Acadia to pay for it on the pickup. Did I read that on earlier fullsize GM suv's that if they had adaptive cruise that regular cruise was not available? If it was an either/or situation, I'd take the regular cruise.

How cold are you talking? The is a bulletin/update regarding rough cold start and on L8T, but only at temps -10F and lower.

What trim level? Different levels have different DIC, with different screens available. Which fuel economy screen were/are you watching? There is one fuel economy number with each of the trip meters -- they show the average since it was last reset -- many reset one of them each time they put in fuel. The more miles in the trip, the slower the average will change. There is also a series of 'interval' graph displays that show intervals (like 25/50/400) - and have an instantaneous fuel economy number on them as well. They will show the average for the most recent 25/50/400 mile interval. The instantaneous number/bar graph will be the economy for the last few seconds. The interval screens will show the average for the last xx miles, the instantaneous and the best xx miles. The 'best' number can be reset.

Still no build and price for 2021 15/25/35 pickups on the GM Canadian site.
