2007 GMC Yukon 5.3L with Low OIL Pressure/STOP Engine Warning Message 🛠🧰😬
Вставка
- Опубліковано 3 січ 2023
- www.amazon.ca/.... Repair video of how we attempted to correct a LOW Oil Pressure Warning message on our 2007 GMC Yukon 5.3 Litre V8. We used SEAFOAM in the oil crankcase to hopefully flush out any sludge or contaminants, followed by a Fresh OIL & FILTER change with Quaker State 5W30 Full Synthetic Oil. This particular vehicle has the Active Fuel Management system so I as well show how I by-pass the Active Fuel Management system with a Range Technology OBD Plug n Play adapter. I have to add this Plug n play adapter by Range Technology works great!👍🏻

Change the screen under the sending unit located on the back of your intake. If its not knocking its lieing. Also change the o-ring on the pick up tube in the pan. Use ac-delco filters only. Do not listen to anyone who says different. Fram wix "auto store specials" are not gm approved and will cause lower oil pressure. Run seafoam in your engine 50 miles before a oil change. Run for about 100 miles and do another one. Leave 1 qt of oil out and add a 1qt of atf run until your next oil change. IF none of that helps then replace oil pump. My 2012 burban loved to pull the no oil pressure trick right before its oil change. 20psi at idle and barely 40 at 70mph. Now its 40 at idle and around 58 at highway speeds.
Put more air preasure in your tires to fix. 😊
If its a 6qt oil capacity use 2qt atf and 4qt oil . Perfectly safe way to flush motor and works great , atf is very strong detergent and wont harm any gaskets or seals
Hey Aaron 👋 I called my neighbor who is a chevy mechanic at a dealership. But he's drunk can't understand a word he is saying . He is celebrating his birthday. All I could understand was make sure its the big oil filter not the small filter. If it was the oil pump would you not hear knocking . I'm no mechanic just a farmer. Have a good night
I will look into these filter sizes. I believe I have a small filter on there, now if there is a larger one then. hmmm 🤔 Definitely no knock runs smooth like butter.🤣
It’s your oil pick up tube O-ring.. you have to drop the oil pan to get to it.
Yours is either cracked or flattened. There’s some labor involved but the ring itself is only a few dollars.
I've used the transmission fluid before works great put it in let run for 10-15 minutes . Do an oil change run it for about 100 miles do another change. Learned from a mechanic he had 40 years experience.
Would the ATF break down or breakup any sludge build up?
@@PrairieSunsetRanch yeah that's why you gotta change the oil and filter after about 100 miles because the filter will be full of crap. After doing this I cut the open and it was nasty and plugged up. I done a few high mileage used cars that I have baught .
@@randybedker1584 Thank you for the info Randy. How much ATF would u put in to that 5.3 crank case to properly break up all the crud?
@@PrairieSunsetRanch I put 1 quart .
10-4 good buddy 👌
Removing oil pressure sensor filter: insert a rifle cleaning brush. say about .223 caliber iknto the pressure sensor hole and remove filter. Poof there it is stuck to the bristles of the cleaning brush with no damage. Judd Lewis
Great tip! Thank you
Oil uptake tube o ring or stuck pressure bypass plunger on the oil pump.
You must’ve done a lotta mechanical stuff when you were younger, you know a lot more than the average rancher
I like tinkering with vehicle repairs, but I am far from a mechanic. I try my best though, kinda self taught to pull wrenches and save a buck or two on the farm. Cheers 🍻 my friend.
Did you get it figured out? We have the same issue with our Yukon.
I use 5w30 valvoline maxlife syn blend for my fords 5.4L and 4.6L
I've never used valvoline myself. How do you find it priced compared to other Full Synthetics within it category?
May need to change the pickup in the pan. Sort of big job but Take pan off and fix the leak and cleanpick up screen
My oil pan is leaking so I might be pulling the plan regardless!🤦♂️
Thanks for writing back. It could be the filter size ?.. hope you get it figured out All the
best
From. Central Ontario. I have travelled the country. Cold
It was brought to my attention there may be a small oil filter and a large filter. Definitely gonna research this!🤔
As far as oil goes in the cars, I like Mobil 1, Valvoline, Supertech seems fine and is easy on the pocketbook. 😉
Anyone I ever spoke to that has/uses Mobil 1 swears by it. Even the 2 stroke oils are suppose to be amazing. Maybe I will price some out! 👌🍻

Another way my dad used was transmission fluid and run it for about a mile with engine hot. the fluid has detergent. Best way is to run Mobil 1or Castrol Syntec Synthetic oil you will have no oil issues
Great tip John! Thanks for sharing & Cheers 🍻 from PSR
Take the oil pressure gauge out and clean
Well at least you got the old gas /oil outa it .. which is a good start.. my next step if were me, be to change out the pressure switch.. doesn’t matter if ya changed it not to long ago.. some of those can be cheap junk an take nothing for them to go bad .. also what ever screen your talking about , clean that too .. if still there after that, id take to shop /garage let them diagnose .. then decide if you wanna fix or let them.. maybe its an oil pump problem.. it starts an runs good an no lower rod bearing or crank bearing noise at all anyways good luck 🤞
I agree with you. I think it could be that pressure switch. Apparently they are notorious for being faulty and unreliable. The screen is worth a look for sure as I believe they are both are in general proximity of each other.
Since you collapsed a oil filter earlier, I suspicion something bigger is going on. I don’t think it’s electrical anymore either since it went up with new oil. Screen?? Oil pump??? But I’m no mechanic. It’d be at a garage already. Lol 😂 .
Chad, this is one time I hope your wrong!😬😱🤣
@@PrairieSunsetRanch it’s a rarity. Hasn’t happened yet, but it’s possible I could be wrong. Don’t tell my wife!! It’ll open a pack of worms if she finds out I’m not perfect 😂🤪😆
I have a friend with this same motor in his truck and apparently it’s got this issue all the time apparently there’s a screen under the oil psi sending unit that needs to be cleaned every oil change he says
I will be looking into this! Thanks Derek.👍🏻🍻
Hello, happy new year
Happy new year my friend! 🍻🎉
Yep check that screen.
And could be the sensor too.
10-4 buddy👌
Absolutely, we will see. Hopefully one or the other that would be ok 👌
@PrairieSunsetRanch cheaper then an engine
At that point the ole girl will be parted out! 🤦♂️🤷♂️
I had a 2007 yukon 5.3 I had the same low pressure problem,and i changed O ring,screen behind the engine etc. Didn't work! The problem were the lifters,after an expensive fix I sold it,I'll never buy a GM product again
Yes this was my outcome unfortunately. My LIFTERS 💥.😱
Oh man i hope it’s just a sensor or something. if not part out will make you somey good money.
ME too 🤞 parting it out would be time consuming however lots of good parts on the old girl.
If oil pressure is jumping around change the sensor.
Yes Im leaning in that direction.
Looks like the symptoms of the bad o-ring on top of the oil pump. Time for a new melling high pressure standard volume oil pump while you are in there, replacing that o-ring. They are not that hard to change. Plenty of videos on UA-cam.
Lifters went bad on me! Sad story for a good ole yukon 😢
I have the fix for you...5lbs of tannerite ...cheers buddy 🍻🍻🍻
OK I like this idea. Make it 10 LBS 💥🛻🔥 🤣😂👌
Check for a leaky injector. Maybe have them cleaned?
So what was the issue
Lifter issues!🤬😱😱
@@PrairieSunsetRanchthat’s sucks i’m really hoping mines something simple..
First 1st 🥇
😮 U were on it in seconds! Thats what she said right?!😂🤣👍👌🍻🍻🍻🥇
@@PrairieSunsetRanch Yuppers👍😆🤣
Lmao 😂 Beauty 👌
Those f…ckin Chevys you can’t kill them😆 i don’t know 🤷♂️ what’s wrong with it lol
With the exception of the Active Fuel Management system they are pretty solid trucks. I remember taking my old 2005 Chevrolet Avalanche with a 5.3 Litre all the way to 688,000 Kms on original motor and tranny! I chit you not. Cheers 🍻 buddy
How many 🥃🥃🥃🥃🥃 does it take to buy a Gm product? Lol. I don’t know if I could get that drunk anymore. 🤔🥴🤷♂️
LMAO 😂🤣. You'd have to have your beer goggles on to buy and drive home in that TURD 💩
That truck runs and starts too good to actually have shitty oil pressure
I think you're gonna have to pull the pan and have a look
That will definitely need to be done that pan is leaking like a sieve.🤣
I know that's why I'm hopeful. Betcha it's that cheap ass pressure switch/sensor. Just had it changed few months back but they constantly fail. Apparently not super uncommon for them to fail right outta the box.
The oil sending unit / preasure switch maybe weak or just cheap junk
It is only a few months old but those Pressure switches are made friggin flimsy and cheap! 😬
@@PrairieSunsetRanch I have bought one chinnese knock off lasted 3 day's Friggin junk
Can you get to the point. Come on here looking for help not all the extra commentary 🤦
