I just picked up a 06 Sierra last night. i was just wondering if it it would be ok to put a quad in the back and go about 300 miles? the truck only has 100 miles on it and the quad with my camping gear probably weighs 800 pounds. should i just cancel the trip or should it be ok? i havent had a chance to read the manual yet but i know my old truck said to wait 1000 miles before towing.

The break in period seems to be related to transmissions and gear units rather than engines. Aircraft engines require full throttle break in and large diesels are ready for full work right out of the box. gear units require that proper surfaces be built up on the wearing faces.

 

I think if you take it easy, keep speeds down and not climb any steep hills you will be ok. gentle throttle is a major part of the process. baby it and enjoy your trip.

800 pounds.....I don't think that a problem.

Take it easy for the first 500-1000.

 

If you were going to tow a 6000lb trailer, that would be different. ;)

I think you would be fine hauling your quad in the back of your new truck.

Just avoid cruising at a steady speed for your entire trip, you should try to vary the speed if you can.

Shouldn't be a problem. Break-in means varying engine speed and that means going up hills and down and on flats. If anything the slight additional load will cause the tranny to downshift a bit more, which is good.

 

The key to a good break-in is that engines like to run at constant speed to wear in, not at suddenly variable speeds. So, don't blip the throttle because that's bad for the engine. Running under slight load, not freewheeling, at various "continuous" (i.e., more than a couple of seconds) speeds, is good for an engine breaking in.

 

Full loading isn't good for the engine, but the quad would be kind of like having 4 people in the cab, wouldn't it?

 

And what good is a truck if you can't haul around your quad in it??

I'd do it if it were my brand new truck. I'd just take it easy. And don't worry about breaking it. That truck'll hardly notice the load.

800 lbs in a 1/2 ton bed is quite a bit of load. My deuce and a half would probably not notice it, but it is a 5 ton payload rated truck for highway driving, and in reality 10 tons would not overload it, given its rear spring capacity of tandem dual axles.

Perhaps using the tow/haul mode would help. This will raise the transmission shifting point and eliminate lugging of the engine on steeper slopes.

A 10 ton Quad? Wow!

 

:sigh:

 

Seriously though, the manual says nothing about dragging around three 200+ pound passengers.

 

I wouldn't really worry about a quad, but that's JMHO. I drove around in my "new" truck with a snowmobile in the back all winter, with no ill effects.

      No 12v outlets in 2026 gmc Sierra

      By PhilB · Posted

      It is possible to add your own 12v outlet to your truck.  Check out this video:   I verified via GM Upfitters that pin 31 is the same on the 1500 trucks.  The wire is GM part number 84779405.   You can get the GM 12v outlet from Amazon  https://www.amazon.com/Genuine-Accessory-Receptacle-25774623-13549530/dp/B0F1H9YRGF EWAY 12 Volt Power Adapter for GM   https://www.amazon.com/EWAY-Chevrolet-Silverado-Cigarette-Ignition/dp/B0915RRW6Q/ref=sr_1_1?   I just haven't figured out a good place to put the 12v outlet in my truck.   Some people are getting USB-C to 12V adapters  https://www.amazon.com/WYMECT-Cigarette-Lighter-Socket-Adapter/dp/B0F87WNQKB/ref=sr_1_1_sspa? Not sure if they provide the correct amperage that a device like a tire inflator would need.

      Wiring Help, Please

      Thanks; I looked there a few minutes, and I think I can find something. I really never looked there, as I thought it was stuff like PTO/aftermarket bodies/accessories like snow plows.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉
