1997 Sierra 100k Tune Up


Recommended Posts

Posted

I'm looking to give my truck a tune up, as it has 100,200 miles on it as of today Things I've thought of so far:

 

Transmission fluid and filter change (just dropping the pan, no flush)

New Fuel Filter (which has already been ordered and I'll probably put it in the next couple of days)

New Shocks (I think the ones I have are originals)

New brake pads

 

These have been done in the past 2,000 miles or less:

New Iridium Spark Plugs

Oil Change (synthetic) and new Oil filter

New front tires

 

Any other suggestions for those that are familiar with GMT-400 trucks? I plan on keeping this truck for as long as possible, since I prefer the GMT-400 style over any other style truck, even the newer trucks oddly enough, and hope to have it run at its best.

Cant tell if you have a 4X4....so if you do...change the T-case fluid and both diffs...if its a 2wd...change the oil in that diff.

 

I would flush and fill the brake fluid too...and Power steering.

 

Oh and check the pH and concentration/freezing point of the coolant.

... might also be a good idea to have a good injector flush ... Vortec injectors can be a problem when deposits start to build up on the poppet valves

 

... at the 100,000 mile mark you should check the condition of the distributor cap and plug wires as well ... these ACDelco plugs and parts are usually good for over 100,000 miles

 

... and then with freshly clean injectors and good ignition parts ... when the truck begins to get hard to start, you can focus on the fuel pump, knowing the other stuff is all good!

Check your front end really good. Here in Michigan we have bad roads and it does a number on ball joints, tie rods, etc. I have also seen plug wires, caps, and ignition rotors fail at less than the mileage you have especially in humid conditions.

This is what I would do...

 

One can of seafoam in fuel tank,

change oil & filter, gas filter, air filter, pvc, check belts, all fluid levels and just enjoy the ride.

Most importantly watch your coolant level as these trucks seem to have a problem with the intake manifold gaskets leaking so you start losing coolant.

 

After a few tanks of fuel add another can of seafoam to fuel tank and fuel system should be clean and good to go.

 

I'm old school, if it ain't broken don't fix it. just stay up on your proper maintenance.

 

Spend your maintenance money wisely: big cost item is trans and differential, change oil in them if you do not know when they were last serviced.

 

 

Sounds like you got it covered pretty good.

    • 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.  
    • 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. 😉
    • Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
