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

[@michaelking4578]

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.

[@anthonybryant584]

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).

[@bigbry4654]

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?

I agree. I did my trans at around 100k didnt wanna wait any longer. And I change with mobil 1 advanced synthetic every 5-6500 miles

[@EATSLEEPFARM]

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

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

[@wildmoondust]

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

[@dannymartinez8522]

So if you get the misfires it won't affect the pistons only the lifters? Is this a common issue? I heard that I disactivate this option

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

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.

[@RickShort21]

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

[@stevemino142]

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

[@twwtb]

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.

[@robertrosicki9290]

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 .

[@jasonrock5220]

Thanks again 2011 Silverado 150,000 Still going strong 💪

[@Agk3los]

09 Silverado with 176K miles on it. So far I've had to replace the throttle body, Bank 1 downstream sensor, throttle position sensor, and the dashboard plastic (got a huge crack going across the whole thing.) Things I haven't replaced are some interior trim pieces that have just kinda come "loose" but not in such a way they make noise so it's not anything I prioritize. Today I got a code for the bank 1 sensor 1 O2 sensor, so I guess I'll be replacing that. Thus far the engine and transmission have been rock solid as far as their performance.

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.

[@billydenham9313]

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 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.

Aftermarket universal coolant is green.

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.
