New diesel owner here....appreciate your videos....learning alot
Great to hear! Glad they are helpful.
New diesel owner,
Thank you for the tutorial, well explained.
Thanks
Thanks for taking the time and care to share your video with us. Nice work !
Thanks a lot for showing the priming process.
A few other videos change the filter, then just crank the shit out of the truck for 30 seconds with a dry filter. Hurts the soul.
Thanks! Excellent video.
Thank you worked great on my 23 Yukon 3.0
Great to hear!
Thanks. Helpful video. Haven’t changed yet but soon time.
Glad it was helpful!
Great explanation!!!!
Worked great!! Thanks for the video!!
Great to hear!
Appreciate ya! They wanted to charge $150 for this, and as it needs to be done every 20,000ish miles I'd rather do it myself. "My" dealership is hot garbage and I'd bet money they would just reset the gauge and call it a day. Haven't had a single visit where everything went smooth, and I've literally only went for oil changes with tire rotations.
Dealerships and any regular mechanics ( not really good one and trust-able one) in fact ruin cars a lot more while they’re approaching
to fix it.
Thanks for the tips!
Happy to help!
In order to utilize the drain plug on the filter housing you need to back the housing off after you loosen the drain plug when you feel the housing start to turn easy stop and pull the drain plug the rest of the way out if need be turn the housing slightly to make sure seal is broken and housing will drain out for minimal mess this is why you didn’t get any drainage when you pulled the drain plug initially.
It was nice to see I didn't have any water in the fuel by removing the drain. I was trying to follow the GM service procedure to provide that info. I like your input on this and may give it a try next time around. thanks!
@@DemonWorks
I like your approach and methods your videos are well done and enjoyable I just thought I would mention that one step been draining and pulling fuel filter housings for a number of years same principles apply no matter who makes it just like when you dip a straw in water and place your thumb over the end and lift it out water remains trapped in the straw until you remove your thumb and air can freely flow through the straw to empty it. I just bought one of these 3.0 Duramax Silverado’s picking it up this week and glad I’m missing out on the cylinder deactivation on the 23’s I thought start/stop was ridiculous on a diesel but that is really dumb in my humble opinion but what the hell do I know I’ve only been working on turbine and diesel engines for 41 years lol. Keep up the good work your my go to info guy on these impressive 3.0 mill’s so I’m subscribed.
@@adamtaylor5590 I appreciate your knowledge and kind words !
Welcome to the 3.0 community! No word on if this updated engine will get that cylinder deactivation, yet. I agree on that start stop… thankfully we at least have the button to kill it.
After I change my fuel filter I normally push the start button (without my foot on the brake) for five seconds to purge the line. It takes around thirty seconds...
I like to lube the new "O" rings with a small amount of grease before inserting the filter into the housing. Then lube the 2 blue "o" rings and the inside the filter green "o" rings before I reassemble. Less o fa chance of a tear.
If that housing is plastic, I wouldn’t spray brake cleaner on it. I’m sure it’s very durable but brake clean is unbelievably caustic on most materials. In my experience, it tends to make plastic parts brittle. A blast with compressed air or a water hose is the safest bet for getting rid of big debris.
Some but not all will. Non chlorinated doesn’t hurt plastics.
No way would I risk water, 💦 🤦🏻♂️ those caps are very hard, cast molded plastic. Trust me when I say the brake cleaner has no effect on it. He was using CRC chlorinated while I prefer the non-coordinated dries quicker, but it’s extremely flammable. Compressed air is not gonna remove any oily residue. Remember, this is your fuel system, keep it pristinely clean! #JustSaying
What fuel additive do you use on 3.0?
I just changed out my filter on my 2017 2500 duramax with the Allison trans. I used a Baldwin pf46126. I felt like it seated in the housing but never really felt the "pop" like it was fully locked in. Can anyone shed some light or have experienced this?
I am looking at buying a truck with the 3.0 L diesel engine, would you have any recommendations on a new vs used?
Thanks
I have a 3.0L 2023 Silverado Diesel. Is it the same filter as the 6.6? $130 is the dealer price to replace. Crazy
Recommended milage to change? I bought my truck private party, 21' w/53k and I went ahead and changed it here at 57500 miles & dash fuel filter life showed 7%. Forums I see a lot of conflicting info. Do you find GM service manual is to soon or to late on changing? (Obviously quality of fuel dictates this but assume its standard quality diesel). Trying to determine my interval. Note: I do still have some of the 5yr /100k power train warranty remaining till next June I believe is the month the truck was purchased. TYIA
make sure the new filter completely seats into the housing. It should snap in and not be able to be easily pulled out.
I saw him snaping filter in place.
My dealer charges $136. for this. It cost less than $30 for the filter and 15 minutes of my time. By the way, last time I checked, Rock Auto has the GM OEM filter for less than Amazon.
Thanks for the info ! I haven’t purchased from Rock Auto before.
@@DemonWorks They usually have DexosD and oil filters in stock too...shipping is really quick.
@@DemonWorks rock auto is awesome! You pay shipping, but if you’re ordering in any quantity, it’s well worth the savings.
Hi, I was told never put a dry filter add diesel before restalling is this true. I see you installed it dry ???
Almost excellent video. No lub on the o rings and no torque wrench? When you tighten things by hand whose hand strength should be used? At least you showed how to prime the filter. I’m still going to look at a few more videos before I change my filter for the first time!
Take a look at this one for more up close tips th-cam.com/video/SSKUcy5Yyd4/w-d-xo.html
New Diesel owner here. Great video!! When you prime the filter do you hold the start button for two minutes or just press it once ? Thank you for your time!!!!!!!!!!!!!!!
Sorry. I read further down and found the answer in another comment.
I can't wait until someone post a video on how to change the belt driven oil pump
I will do one on the belt swap when I have one to do.
Isn’t that where you have to drop the tranny to do? Plus it’s around 350,000 kms from what I’ve read.
You won’t ever have to change it. Just sell the truck!
I just paid 180 for this service. Wish I would have looked into what it took to do this.
ouchhhhh at least you will get it next time
I’ve changed my own 2 times before this will be the 3rd. But for some reason this time I can not get the housing off. Have that same socket. And for some reason the housing is INCREDIBLY tight. Socket is trying to round off the edges. Can’t get it with that or a filter wrench I’ve tried. Housing will not budge. Any suggestions???
Get a replacement cap before you go any further. Once you hjave a new one, just keep muscling it. SOunds like possible overtorquing beforr or lack of lubrication on the o-ring.
@@DemonWorks okay thanks. Appreciate the feedback!!
What do you do with that fuel that comes out?
Catch it in a pan and then I put it in a container I have for used oil. Can be taken to any auto parts store for dumping.
Do you change it every oil change or every other??
10-15k is my typical interval. I believe the dash will put you at about 25-30k
You didn’t actually push the brake to start to get the filter to prime the first time, you just push the button, do you have to hold the button the whole or just once an wait?
If you push the brake, it will start. Just hold the button down for a few seconds and it will turn the pump on.
@@DemonWorks that’s what I thought but wanted to make sure, I love my 3.0 but was quoted over 300$ with tax for the filter change ain’t no way I’m paying that for a 30$ part
@@MaineBornRedneck exactly ! It’s such an easy process, too.
@@DemonWorks I’ve never done a fuel filter before in any of my vehicles because the filter location was always a pain, on my mini max same truck as the one in the video but black it’s right there which is awesome for the wallet
@@MaineBornRedneck message me if you have any questions when you do it mstrgoodwrench@gmail.com
How is Amazon for counterfeit parts? Or gm parts?
Make sure you buy from Amazon specifically, not an odd reseller, and they have all come back as genuine (my purchases)
Don't use brake cleaner on that plastic housing. It will damage it.
Newbie question: does the fuel tank need to be empty before you do this?
Good question, it does not. You will only lose the fuel that is in the fuel bowl.
@@DemonWorks thanks for the quick reply!!
Is it the same way for a regular 5.3 gmc sierra 1500?
You don’t have one of these filters.
@@DemonWorks I can't find anything about the fuel filter or pump on a 2019 Sierra on here. Everything is duramax.
@@htwntx7131 yeah, my main focus here is the 3.0 Duramax so I don’t have much content on the 5.3. You don’t have a fuel filter to replace, so you’re good to go!
@@DemonWorks My truck just started acting up today and now won't start. It seems like it does want to start put no gas flow for it to start. 🤷♂️ I don't know I'm lost lol dealership gonna try to charge me my soul for the repair.
@@htwntx7131 yeah, it will need to be diagnosed. Lifters are common and so are valve springs. While yours does sound like a lack of fuel issue, a broken valve spring could cause your no start issue and running rough even without a terrible noise… seen it a lot. Not saying that’s your issue, just that it needs to get diagnosed no matter what.
Don't rev if you have air. Reguardless of if GM recommends it. The CP4 injection pump with air in it greatly reduces its lifespan. It already only lasts 100k miles safely.
Question, where did this injection pump only lasts for 100k thing come from? I saw people say that on a facebook group. I've had several come in for service and running the original pump over 100k, just an fyi
The 3.0 Duramax does not use a CP4, FYI.
How early do you recommend changing it?
I’m going to be shooting for 15k miles. This filter was mega dirty! If I pull it at 15k and it appears to be clean looking, I will adjust to longer intervals.
I swap mine at ~10k. I could not believe how dirty that thing was the first time. And the same thing happened to me. The gloves became almost pointless as diesel ran straight down my arm and into the sleeve of my jacket. 🤣
I got a couple TP1015 kits on Amazon along with a 3/8" drive 36mm/25Nm (18.4lb.ft) "oil filter cartridge" torque-limiting socket thingamajig. Other than it fitting very tight on the cap making it kind of difficult to get on and take back off, it works fine, and it was far cheaper than a good digital 3/8" torque wrench.
Maybe you did it but didn't show it, only recommendation I have is to lube the big o-ring with some diesel so it doesn't rip or bind up when tightening the cap.
@@3.0dmax all good info ! Much appreciated! I did lube it with diesel
No lub on the o rings?
lubricate with diesel fuel on the o-ring - check out this video for more detail th-cam.com/video/SSKUcy5Yyd4/w-d-xo.html
@@DemonWorks yes! Before you install the thing!
yes, I recommend you to lubricate before installation. Glad I could help !@@STEVE-lk2ft
Did I miss something, no fuel came out when you opened the drain.....Why? Dis regard I see thats the water drain, no fuel should come out of a water drain.
Glad you caught that. For others readying, if something comes out, better find a new fuel source
@@DemonWorks Interesting, does the small drain somehow only let water out?
@@kevind1865 correct. However, someone commented that if you open that drain, then start to unscrew the filter cap, it will start to drain the fuel out of there and be less messy. I have yet to try it, but I like the idea.
The fuel won’t come out of the filter drain until you introduce air into the top by unscrewing the bowl a bit. Just like having your finger over the end of a straw full of liquid.
Should have seen what mine looked like changing it at 33k miles. Looked like a used oil filter lol brown and dirty as heck.
33k is a long time !!!
Why the dealerships charge $300 + for the fuel filter change and $100 or so for the oil change. The oil change takes longer and requires more material and parts. Such a scam.
Go to a different dealer.
SMH, I just got hit with this charge during my 30k interval; appreciate the info, will be changing out myself moving forward.
So what you’re saying is…..
Change the fuel filter like every fuel filter you’ve done before…..
I mean…..if you know what you’re doing and have common sense.
why does everyone wear gloves, even for electrical stuff, seems strange. Maybe for greasy cleaning jobs but that's about it.
In my case, it’s a habit to have gloves on all of the time since I’m a tech. So, anytime I’m working on something, I’m wearing them. It’s beneficial in many ways.
Wish I could wear gloves to keep oil and debris off hand. I cannot work with gloves on. I think wearing gloves is a skill.
Two questions for ya as a new Silverado 3.0 owner. 1. I see the first step was the water drain and there wasn’t any. Do you do this more often then only when you change the filter? As a pilot, we routinely check the tanks for water and just wondered if this is an issue in diesel trucks file systems. And 2. Do you have any recommendations for which oil companies have better or more consistent diesel fuel? What has your experience been? Some of the videos scare me on quality, underground tank maintenance and such so I want to make sure I find the best if that’s possible. Also as a bonus, do you use any additives in the fuel? Many tks. Love the channel.
Welcome to the channel and the 3.0 family!
I did the water drain merely to follow the gm procedure, I have never seen water come out. If you do open the drain and water comes out, that should be your cue to find a different fueling station.
The way I choose fuel is to go to a big name (chevron/shell/texaco/76) and make sure I go to one that I know is high volume or is in a potentially high volume area. I tried multiple local stations and ended on my local chevron. The thing I noticed with different stations was the fuel mpg seemed to vary with other stations and the noise level from the engine varied with different stations ( the diesel knock sound on accelleration)
@@DemonWorks ok Tks for the advise. Kinda what I figured too. We certainly have high traffic stations in the area.
@@hammer-r It seems to be nearly impossible to find top tier diesel. If you look at their site there are tons of stations around here with top tier gas but no mention of diesel. I have been using that Hot Shots can't think of what its called EDB something like that. Believe they say 1 oz per 25 gallons something like that on the jug. I usually put an oz of it in every time I fill up. I have only had the truck a few weeks though and only have about 900 miles on it so haven't done much refueling lol. I did a 700 mile trip this week though and I refilled 2x but both times I still had over a half tank. Just mom was driving my old truck with the 5.3 so she was having to stop for gas so figured I would just top off while I was there too. I know the GMC dealer filled it up when I bought the truck but I doubt they added anything and I noticed the engine was quieter when I added the Hot Shots
@@JesseLJohnson Tks for the info. Yea here in northern illinois, there is only one and it’s a Costco about 20 miles away. So I went there and filled up. While I’m no expert on this truck ( I only have 2000 miles on it) it seemed to me to get worse mileage. So what I’ve done lately is hit various big newer stations when my tank was about 1/2 empty. This way if I hit a bad one, I might be able to skate by until the next fill up. Not sure if that’s logical but I’m still trying to figure out what brands around here are the best, if that’s possible. I do notice that most stations have a sticker on the pump stating biodiesel. I’ve heard to try to stay away from that, but it’s hard. I also use hot shots, 1 ounce per fill up. No discernible difference yet. But then again as my first diesel, I’m not fully tuned into its performance and sounds yet. Time will help that. When I get to Colorado this summer, the local Costco has supposed tier 1 diesel and I’ll run a couple tank fulls while out there and see if I notice anything. Let’s hope the crap we do buy out there is good enough for our expensive trucks. I’d love to hear of one of the oil companies state that they do their own diesel and stand behind its quality. I’d be a buyer then.
@@hammer-r I have Costco a few miles from my house but the one here only sells gas same with the one by my parents and pretty sure the one in Mobile by our other house. I just bought this truck its a 23 Denali Ultimate only have 900 miles on it so far. I do know one of the 2 times I have topped it off on the road trip it said the diesel contained 15 or 20% biodiesel and it didn't seem to run as good. That was at I think a Shell station. Driving around town I haven't got any better then 19.5 mpg but its not broken in yet I guess got just short of 30 on the highway
