2011 5.3L 105,000mls. Just replaced rear axle seals. Were leaking into rear brake drum. Took care of AFM issue with AFM bypass plug-in bought off Amazon. Plug into OBD2 port and turn engine on. The plug-in tells computer to run V8 all the time like God intended. No more burning up spark plugs

My 2010 Silverado WT withe the 4.3 liter has 220xxx miles, I would drive it across country tomorrow, plan on shooting for 300xxx miles or more

Glad you mentioned the heater hoses. Any of the 99-13 chevy trucks have that as a decently common problem with the plastic connectors breaking and then losing all coolant. Another one I personally wanted to mention is if that little ground strap didn’t fix weird electrical issuesI’d try the battery cables. Pretty common for the positive and negative cables to corrode internally and cause the whole vehicle electrical system to go haywire (door locks opening and closing while driving, radio completely shutting off and turning back on, gauge cluster going to resting position while vehicle is on, etc).

Little over 200,000 miles on my 2013 silverado no major issues... just replaced one coil and an o2 sensor and plugs ... does burn oil between oil changes now... pretty good truck i must say i think i got my moneys worth out of it ...

2012- 5.3 here w/ 100k miles…. Really no major issues… I run mobile 1 oil and have serviced the trans @30k - (pan drop filter and fluid) … love this video w/ some good tips… I definitely am worried about the AFM issues… I feel like Im over maintaining the truck… but it’s piece of mind… and who wants to buy a new truck now days with these crazy prices?

Have an 07.5 Silverado with 373k on the dash. Still runnin strong too😂

If your having trouble with it smoking during start up or oil consumption start with the driver side valve cover. The factory pcv valve port gets clogged and causes these issues. The updated aftermarket ones fix this issue. Look it up if your having oil consumption problems this fixed mine

Also to add on to the top issues with the GM trucks those years with the AFM (Active Fuel Management) is the lifters on the cylinders that shut off during the 4 cylinder mode (1, 4, 6, and 7) collapsing. If your truck is misfiring really bad on one of those cylinders be ready to pull the head and replace lifters. Happened on my father's 09 GMC 1500 Z71 with the 5.3L and 247k miles

I bought a 2012 Silverado 1500 WT with 284,000 miles. I have driven it for three years and only have needed to change the oil and just today I had to replace the radiator. It's fantastic.

2007.5 2500HD Z71 4x4 CREW CAB DURAMAX 143,000 miles Best 25K cash I ever spent. Looking forward to adding another 357,000 miles to hit that legendary 500,000 mark son!

2012 Silverado 4.3 V-6 with 60k miles. Bought it a few years ago with 58k miles. Inspected and oil changed every year. Only problem has been batteries failing early, but replaced free under warranty. Finally put a solar powered battery maintainer on the dash and no problems since. Fair winds and following seas to all.

Looked like basic/ routine maintansnce (sp) to me. But still good advice.

This channel is the best! Makes me feel confidant to get under the hood and start fixing stuff until I take stuff apart then I doubt myself again cuz I don't know how to put it back together.

The best thing you can do to any vehicle that's up there in mileage is keep changing that oil every 5k kilometers or 3k miles on a GM flush coolant every 2 years the rest is just maintenance really... spark plugs every 4 years or so differential oil change every 2 years transmission oil starts to smell burnt flush it out... GM trucks are the best in the business follow these steps and your GM truck or car will last a long time

2010 Silverado 4.8 with 190K, besides basic maintenance, I have changed the brakes, wheel bearings, the whole front end, spark plugs, heater hoses, rear main seal, valve cover gaskets, and oil pan gasket. Truck runs like a champ! Hopefully I get another 100k miles out of it!

I thrown my engine cover away years ago. I've had problems with headlights and taillights not working. Headlights needed new plugs. Taillights had corsion that needed cleaned off. I use the used motor oil for rust protection by spraying it on the underside and inside the cab corners and rockers and any other places like around wheel wells.

310,411 on my 2007 Silver 1500 WT 4.8l loves these trucks. Proper maintenance and repairs will take you a long way.🤙

I kept waiting for some unique or chronic service issues for these model years but this is just routine maintenance for any vehicle.

Props man I find your videos to be among the most knowledgeable and informative on u tube. The videos have allowed me to do a lot of repairs / updates on my truck without taking it to the shop.Thanks!!

At 9:40, the LSD additive. If you contact chevy, they tell you not to use it with G80 rpo code trucks and SUVs. The G80 is a posi lsd in cars, but the G80 on trucks and SUVs is a locker and doesnt require the additive. I contacted chevy a few times to figure it out as I have a 08 PPV Tahoe with G80. Just for anyone curious

If the main ground strap is ok and you still have weird electrical issues, there are several other ground straps around the vehicle that should be checked, especially if the truck has spent much time in the salt belt. My 2013 calls for dexos specified oil which I think automatically puts you in the synthetic camp and there is an oil life indicator in the driver information system that can help if it was appropriately reset at the last change. Mine is running good with 170k miles. Got the big 4.8 with the 4-speed ottermatic. I bought it recently and am currently doing plugs, wires, air filter, hoses and a few other "catch-up" items since I don't have a full history on it.

Changed my 09 Sierra vapor canister purge valve tonight thanks to this dude, did it on the side of the road standing on 4×4 blocks cause I sit on 35's so thanks dude keep up with the knowledge I need it

I have a 2004 Chevy Silverado with 3 hundred and 33 thousand miles on it not scared to go anywhere in it but i do regular maintenance on it

THANK YOU Very informative. Its like a service manual on video. I spent the rest of the day under the hood doing stuff in the video.

Silverado 1500 daily work truck calling on the average anywhere between 1-3 ton with 207k still running strong I'm so glad I recently discovered that I needed a AFM disabler quickly purchased one and got rid of that annoying lifter tick thankfully I have prevented something disaster is according to all the comments I've read do yourself a favor and get one if you don't have one

Good Stuff! Thanks, My 2007 GMC Sierra is still running good after 200K. Keep up the good work.

I just bought one of these and this has everything I needed to know in it. Thanks.

2013 6.2 liter w 271k miles normal maintenance still running strong as first day. Only change oil pressure switch. 👍👍

As odd as it sounds if the small ground wire between the firewall and hood is rotted out and broken you'll get buzzing and crackling on the FM radio . Had this issue on my 2012 Sierra . Replaced the ground wire to the hood radio issue fixed .

I have a 2010 Silverado 4.3 with 390,000 miles original driveline still runs and drives like new

GMT900s have a G80 which is a combination locker and limited slip which does not require "limited slip" fluid.

Almost nothing specific to 2007-2013 Chevy Silverado 1500 Trucks. Could have been a 66 impala recommendations. Not that info was bad just so generic could have been ANY car.

It's the road salts.... during winter time that eats up ... the under side of vehicles. My 2013 silverado.... within 4 corners of the states, has no rust at 257k miles.

Thanks for this video it helps me a lot I just inherited a 2010 Silverado with 380K miles so yea I got a long road ahead it wasn't taken care of jusr driven hard. Aloha from Kansas

I bought a 2012 April of last year. When I buy a used vehicle, I always change all fluids front to back even the gear oil in front and back differentials. The truck takes 6 quarts of full synthetic 5w30 oil. Here's what happened to me one day.... In January my family and I were coming home from taking my son to the doctor when the check engine light came on. I got the truck home (Thank God) hooked it up to my OBDII scanner and it wash the oil pressure sensor. I was going to replace it but a guy on here told me to check my oil first. When I checked it, the dipstick didn't have a drop of oil on it. (I FLIPPED OUT) I just paid $18K on this truck! So, I went ahead and ordered both valve covers because I wanted both of them to be clean and to also match one another. I've installed both of them, but I've not checked to see if it worked because after installing them the passenger side pcv outlet on the new one has a flared end on it and the original didn't have that. So, I went to Advanced Auto to buy a rubber hose to use on it after I cut the pressure clip off of the pcv hose. I also decided to get me and new gas cap while I was at it. Anyways, I hope and pray that the new valve covers help the "Oil Consumption Problem." I'm sort of worried about it though because that's a lot of oil being consumed in just 4,000 - 4,500 miles. Yes, I've also checked for leaks and there were none. I've seen vehicles that are burning oil, but this truck doesn't do like that. The only time I've seen blue smoke out of the exhaust pipe is when climbing a hill, but it's just a small amount and then it's gone. If you were not paying attention to it, you wouldn't notice it. I've also checked my antifreeze for oil to and if good. Another thing, after I change the oil the dipstick doesn't read right which has me stumped. It should be on the full area, but it shows as if I put 12 quarts instead of 6. I'm thinking it got the wrong dipstick in it, but if anyone knows something different let me know

You said check transmission fluid in drive. I think it should be checked in park. At least that is what my owners manual says.

Gm was a good company from 07 and down. Even better was 2013 after that they went down hill.

368090 on my 2006 Silverado 1500 4x4 oil change every 3000 So far so good

Would have been nice to mention that AFM may may guarantee that you will not have concerns with a high mileage engine ! Your only concern will be to do high cost repairs to your engine , or to get a replacement engine without AFM !

Excellent comprehensive checklist, and advice/guidance, for home mechanics. Thanks!

I could be mistaken, but I don't think that model ever came with a limited slip. they have a mechanical locking diff The "Eaton G80". Great video though. Very informative!

I worked on a 2007- 1500- silverado for about a year what a piece of junk, heat and air conditioning and vent problems and GM knows about it, example select ac and heater comes on and won't change or vents go whacki couldn't figure out settings selected, computer issues in the dash. Recommended Fix replacement of heater control stack in middle of dash, Very Expensive, and this truck only had 81,000 Miles. Now under the spare tire attached to bed is a black box some have 4-6 large brass looking connectors and when salt and water corrode them it causes it to send false messages throughout the truck and computer sends false codes. Like Bad fuel pump and a host of other things, little black box and connectors very Expensive and after replacing dealership has Reprogram everything. Very Expensive.

If it feels like it is misfiring, but you have replaced all the spark plugs and wires. More than likely your transmission is going out when the converter is about to fail it will feel like a slight misfire.

I still like these trucks, despite the fact that they're not the best on gas nor the most reliable vehicles ever. Better than the older Silverado trucks but not as costly as today's Silverado trucks.

I have a 2013 sierra with 4.8L and 200k mi. No AFM and no lifter issues lol.. And guys i knew at the time i got it made fun of the size.. I still have my truck on the road

Awesome, handy to have this saved. Moved to Canada and picked up a 2012 5.3 4x4, love it but intimidated at the same time coming from European cars 😅

Great video! Why not do this for ALL vehicles? This is GOLDEN Sir

Great video I just bought a 2013 Friday

I just hit 225k on my 07 Tahoe Z71 (11/30/23) never encountered a tick but i am asha of using the oil life system but now i do 5k or ever 6months with full synthetic oil Valvoline FullSynHM

the tech missed the power steering fluid color. His looks red. It should be golden colored. The red is probably transfluid that someone used in a pinch instead of dropping $30 per pint for the unicorn blood at the GM dealer.

Great video thank you for the knowledge and informative steps for routine maintenance. I just bought this truck it is my first truck and your video helped me a lot. Definitely deserves a like, share & subscription.

I feel like this video applies to any make/model used vehicle, good video for the beginners out there

By today's standards - What is considered HIGH mileage ??? Things are much different than even 25 years ago.

Good advice and good background tunes. I danced the whole time watching this. Thanks!

I thought this was going to be issues specific to this vehicle itself, but this is literally just basic maintenance. Doesn't say anything about this car that you don't have to do for basically almost every other vehicle on the road

2013 5.3 1500 169,800 only thing I needed to replace was an oxygen sensor

If the battery is still doing its job why replace it

You missed so many things. That's just routine inspection everyone should do before buying a used car. If you want to be specific, brake petal switch, electric window switches (all doors), steering angle sensors, evap solenoid (P0446), extended cab rear door latches, lifters for AFM (if equiped), 4 wheel drive engagement (if equiped), just to name a few specific to this year range.

Super informational! Thank you

Great video. I have told my friends to watch your videos. Best how to vids and your TRQ parts are top notch. Thank you!

No matter the vehicle, I'm in the habit of changing the coolant every year. the ph level gets high from combustion gasses and heat cycles and it becomes more acidic. on old cars the radiator & heater core were copper-brass, but now the modern cars use a very light aluminum, probably an alloy of some sort. it's not as robust, but it cost a lot less. I got my 1st mechanic job in 1984 and done plenty of heater cores over the decades. they ain't cheap. so I change my coolant relatively often, it is cheap in comparison.

Driving a 17 Silverado High Country 6.2L. Coolant will be 5years next April. Only 43,000 kms. Is it necessary to replace it? Great content as always. Cheers

Dept of transportation, needs to come up with another solutions.... to take care of roads and to prevent rust on vehicles.. during winter months

If you live anywhere up north then the biggest issue with these trucks is rot

Bought my 2008 brand new so far the 4.3 has been solid nothing major has gone wrong with the truck but it is very low milage so we will see.

I got a 2013 with 316k miles and it runs great. I’ll drive it to another country no prob

Aftermarket universal coolant is green.

How do you check the motor mounts on a Silverado of Sierra, 2010?

08 5.3 with 205k miles. Runs good.

GM royally screwed up the LS platform with DoD. 07 & up all are and will be crap. DoD will cause oil pressure and lifter issues.

was very skeptical bought amazon key fobs 09 chvy 1500 silverado and it worked just like this now i have 3 fobs and my trk worth more money if want to sell

Cylinder shut down ruins motors. Floods cylinders with oil. Burns oil and fowls out plugs and oxygen sensor. I being tired of replacing plugs and oxygen sensor. Removed solenoids replaced top of motor deleting program. Now I have a good running truck. Not burning oil. Also no hesitation to turn on cylinder fire when pulling into traffic. Cylinder delete is a terrible idea. Its for emissions but once you start burning oil not very good for emissions.

Did you say check the tranny fluid in drive and idling

I have a 07 Classic and have already replaced the rear end, the drive shaft, u joints, transmission, tie rods, rack & pinion, radiator, brake master cylinder, the motor, pulleys, belts, rotors, calipers, fuel pump (3 times), ball joints and alternator. I think that's all 🤔 Yes its basically a brand new truck now😂

My 4.3 2012 gmc has just over half a million miles and runs strong

My heated seats always turn on and off randomly and lights dim at night randomly could this be the gray strap wire that gets green over time

"This should be orange Dex-Cool." And the faster you can drain it out of there and replace it with a compatible non Dex-Cool fluid, the longer your truck will last.

Excellent vid, very thorough, thanks for the info.

Let me just raise it up on my $2000 car lift in my garage

Ignition switch

No cabin air filter? My 01 basic Silverado has 2

08 176,000 4.8 running strong rust bed wells rockers just replaced front tie rods

Good video, thanks. Fuel filter in tank?

You forgot the traction control

When your truck has a documentary on its issues

The title of this video is completely inaccurate. What you'll see with this video is along the lines of annual inspection and maintenance - nothing more. "High mileage issues" are a completely different animal and none of them are covered. Usually you folks do good stuff...so this video is largely disappointing.

Very informative!

I was told by someone, don't remember who, hood ground strap helped with RFI shielding, this true or not? 🤔🧐👨‍🔧🤷‍♂️

If you’re unsure if you have an LSD, do a burnout. If two tires are spinning, LSD ✅

I found a good deal in a 2006 silverado & a 2008 which truck is more reliable?

Can you make one for the new body style 14-18 chevy/gmc 1500

09 sierra 1500 223000 runs good but I know nothing lasts forever. Been very dependable truck.

its good to do this on any car

P219A code on these trucks? Haven’t found much information. Replaced both upstream oxygen sensors with denso. Cleaned mass airflow sensor, changed filter with delco. Two quarts of mystery mix oil and hasn’t came back.

Mine is a 2013 and it used oil really bad. I read an article that chevy is being sued over this issue. They admitted to the flaw but didn't do anything about it. Apparently they designed it to spray the pistons to keep them lubed. If anyone know how to fix this problem please let me know ❤

"Top high mileage issues" - should be called "preventative maintenance on every vehicle ever"

+1 on the ground strap

250000 on my 2008 2500

Yrah last tome i wemt looking for a hogh milage chevy like that , 150-190k miles they were asking $15k , nope no way
