100k Maintenance?

I am due for an oil change and a new fuel filter.
I am a few hundred miles short of 100,000.
Besides looking in the manual...what do you recommend I have done 'preventative-maintenance-wise' when I have the truck at the dealership for the other two items?
Flushing systems?
Replace small engine components?
I have no other issues right now...so maybe don't touch?!

Wow -- great information from you all!
So it seems its a resounding agreement on FLUIDS!!
I was hoping for one or two items -- but many more than I thought of course!

Either way, this is good timing as we have a 1,400 r/t trip in a few weeks -- and then in July we have a 6,000 mile r/t Cross Country Trip 🙂

Seems this is the list I should give to the Dealership:
(totally NOT looking forward to the bill with this Duramax!)

Oil Change & Oil Filter
Fuel Filter Change
Transmission Fluid Flush & Filter
Brake Fluid Flush
Coolant System Flush
Power Steering Fluid Flush
Rear Differential Flush
Front Differential Flush
Transfer Case Flush
Rear Axle Lube

Inspect Brakes
Inspect Belts

Did I list everything correctly?!

The "transmission flush" services I have seen done is not a externally powered/pressurized flush that everyone seems to freak out about.

You just hook up the trans cooler lines to a setup that pulls fresh fluid in one line and collects the old fluid from the other.

Then you start the truck an let the trans pump circulate the fluid until it comes out clean.

WAY better then the old "drop the pan, drain the converter, and fill it back up" way of doing things.

Good advice. For some reason idler pulleys on GM's seem to be a fairly common failure point.

Advice to flush coolant is a good one. Dexcool is fine as long as you maintain it, and at 5 years old your coolant is ready to be replaced.

Differentials, transfer case, and Allison Tranny fluid/filter changes are great ideas too.

I'll jump on my personal soap box now: FLUSH YOUR BRAKE LINES :C

I don't know about your '13 truck, but the '99-'07 GM trucks were notorious for badly corroded brake lines that would suddenly rupture. You can't do much about exterior corrosion, but flushing the lines keeps moisture out of the inside and will prevent internal corrosion.

On my old '04 2500HD I realized at about 60K miles I'd never flushed the lines. I used a little Motive Products Power Brake Bleeder to flush them and I could not believe the difference in braking. As fluid ages it gets contaminated and does not compress as well which requires more pedal pressure. After flushing the system I was amazed at how little brake pressure it took to stop the truck. :E

That's what so many seem to be unable to get through their heads. It's a lot cheaper to aggressively maintain a vehicle, than it is to repair whatever fails prematurely. I do a similar PM schedule on every vehicle we own, and have done so for the last two decades. I rarely will mention it online, since the usual response is, "whatever is in your manual". Or somebody "educating" me on what a waste of time and money it is.

Twenty years ago I bought a new Dodge Intrepid, which over time got a well deserved reputation as fairly poor vehicle with an awful engine. It has had maintenance that exceeds the severe duty schedule, since new, and 5K oil changes. It spent a few years as a daily loaner for a repair shop, and it currently runs just fine on the original trans and engine, with over 300K on it, and no significant repairs. In the ten years, and 200K miles I owned it, I spent almost nothing on repairs.

Sadly, we have reached a point where drivers are destroying their vehicles, since they have been brainwashed into believing that they own a maintenance free transportation appliance. My mechanic buddy reports that his shop ends up with at least one engine replacement job a week, on fairly new cars. Customers are using the car's "maintenance minder" to determine when oil changes are needed, and frequently ignoring that warning light for a while. As a result they are grenading motors due to not knowing that the engine was consuming little oil from the last change to the 5-7K mark, but starts to guzzle the stuff as the mileage between oil changes gets to the 10-12K mark, which can be before the change engine oil light even comes on. They don't check the oil regularly, and end up destroying an engine that arrives at the shop, with a quart or two in it. The other issue is that they end up at the 100-125K mile mark and have done oil changes at 10-12K intervals. The car arrives in limp mode, since the variable valve timing is shot, or the cam chains, guides, tensioners, valves seals,etc.... are totally worn out, and it needs thousands in repairs to the top end.

As you might guess, if they can't be bothered to check and change the oil regularly, there is zero chance that anything else was maintained on a regular schedule, or done at all. For somebody as picky as I am, it makes it nearly impossible to find a used vehicle. I'm shopping now, and it's a 1% shot that you can find evidence that any used vehicle has been regularly maintained.

I changed my serpentine belt and idlers at 100,000 just to be safe and keep the removed belt in a plastic bag under the seat if ever needed in the middle of nowhere. Be sure to replace the idlers at the same time. My truck has two alternators so there are two idlers. When being removed one of the originals fell apart. I was lucky I was changing it anyway.

Do check the manual and ask for the specific items only. If you go in and ask for a 100,000 mile service you can bet on top of everything else there will be an extra $600+ pad on the bill.

Ive flushed my trans several times and never had an issue with it. Cooling system on the other hand, I waited too long and the coolant broke down and coated the inside of my system with brown goo. I couldn't get rid of the heat. If towing you should follow the extreme duty criteria. I should have changed coolant at around 40K miles instead of 75K miles. Cost me a radiator, aux cooler, bypass valve. Can get pricey.

Transmission and 4WD transfer case were due at 90K. Make sure to use genuine GM fluids, no aftermarket. I would also flush the cooling system. A true "flush", none if this "run it through the machine and add some magic chemicals" for all of the above !

I do similar at 100K, nice starting over point. However trans likely would have also been done at 50K or less, brake fluid every 2 years, PS fluid likewise. Coolant, every 3 years or so.

GM specifies a specific rear axle lube for the eaton autolocker on the duramax. Commonly known as "grape juice" because that's what it smells like.

For the transmission I'd recomend using Transynd not DexVI. As long as your changing it, why not go for something far superior to DexVI.

Several mfg have Transynd TS-295 certified fluids.


Often the rear diff/transfer case/front diff don't have a change interval specified. doing it at 100K is IMHO a good idea.

And check the brakes, new shocks?

Fount this on the web.

Looks like it recommends between 97 and 105 K:

Rotate tires, if recommended for the vehicle, and
perform Required Services. Check engine oil level
and oil life percentage. Change engine oil and filter,
if needed.

At 150,000:
Drain, flush, and refill the engine cooling system (or
every 5 years, whichever occurs first).
Drain, flush, and fill hybrid low pressure cooling
system, if equipped (or every five years, whichever
comes first).
Inspect engine accessory drive belts for fraying,
excessive cracks or obvious damage (or every 10
years, whichever occurs first).
Change brake fluid (or every 10 years, whichever
comes first).

Flush??? Transmission may be due for fluid and filter change, but the power flushes seem more detrimental. Water pump and coolant may be worth changing and or flushing.
Depending on your truck, and what you have done recently you may want to have the injectors cleaned/serviced, bearings and brakes checked as well as the transfer cases.
After all that if yer wallet is still thick, go fill er up and drive.

Other than the scheduled maintenance items, if it ain't broke, don't fix it.
