Does anyone have a problem with water runnning out of the seal on the roof when it is moved while drying the vehicle? If so, advise what steps can be taken to correct the problem.

I do not understand what you are actually talking about. Is this water running into the vehicle or is it just holding water around the base and that water trickles out and is leaving water spot stains on what it likely a black vehicle. If water is getting into the cab, take it in for warranty work. If this is just the inconvenience of having to remove the water spots the next day due to the water being released after the truck has been dried, your best bet would be to find out how to lift the antenae up from the roofline and run a bead of whatever colour RTV silicone blends in best with colour of truck. You will want to put antena back into place and tighten it up. Wipe up any residual silicone that gets squeezed out. Do it while wet, unless you are good with a razer blade. Once it is cured, someone that is good with a razer can cut the excess sealant without cutting the paint.

My question is will this cause a leak that does come in around the drivers sun shade or down the "A" piller. I only have 3000 miles on it. Do I need to take it to a dealership and have them look at it. :rolleyes:

Are you getting water inside the truck on the drivers side floor, or are you seeing any water in the interior?

 

Main reason for taking it back to dealer is to make sure there is a record of it happening, and a record of them fixing it. If for some reason it starts to do it again within the next couple of years, or if you start getting rust through, and it was caused by the leaking antenna that GM has documented you complained about it when truck was new it will go a long way in getting it handled.

 

No one on an internet forum can possibly answer your question directly. It would need to be actually looked at to diagnose. In its simplest form, any hole in a panel that is sealed to outside elements can have a gasket or seal fail and allow water into the interior. Were it me, the truck would go back to dealer to have them look at it for me. In my case, I have either bought or caused the sale of 12 new vehicles since 99, and all from the same salesman. Needless to say I get treated very well, and rarely have any problem getting them to look at something that may not be an issue at all.

      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. 😉
