That’s because they last forever

[@swkohn1279]

Here are some major ones that need to be checked and can affect your purchase. 1) CHECK THE TRANSMISSION FLUID!!!! The fluid needs to be changed on these trucks or serious damage will be done. We had a farm truck that needed a while new transmission because it was not maintained. A clean filter is also a necessity. However, DO NOT FLUSH THE TRANSMISSION! It can cause too little friction and mess up worn out parts. 2) Check the rear fender wells.the bedsides will rust from the inside out depending upon how much damage is done. It is also structural for the rear quarter panel. The rear support will crack then by the taillights will follow affecting the tailgate bracket. 3) Assume you need new sparkplugs and a fuel filter. If there's a check engine light on their typically the culprit. Just under $100 and it makes a world of difference. 3a) The spark gap on the plugs can vary from the original specs depending upon which engine you have. It varies if you have iridium or platinum. Do your research. 4) Cab mounts. The cab mounts on the earlier mounts tend to go. Look carefully at the bushings. If not replaced when broken they will hold water rusting out the mount. It can become costly to repair, potentially damaging the front mounts in the process. 5) Tailgate latch. The plastic connector which holds the release for the tailgate can break easily if yanked upon. Always push into the tailgates before opening them. The plastic becomes brittle. 6) Bumpers. The bumpers usually rust out horribly. There's no way to repair it, it's much easier just to install new ones. The way the market is right now, there's a lot of these trucks for sale. Keep in mind that a cheaper truck could cost you more in repairs. Attempt to find the best truck cosmetically and mechanically in your budget. Parts are cheap and the repairs are typically pretty simple, remember you can't undo rust. Good luck.

Best truck chevy ever built. The 6.0 gas engines easily go past 500k miles.

[@JustAnOldMan]

this is more of a regular maintenance video than issues with the specific truck - chev 2500 hd

[@sad8181]

On my 2000 2500 I’ve done the following; all ball joints, front shocks, water pump, intake manifold gaskets, new OEM intake manifold, water pump, idler arm + bracket, pitman arm, both front hubs and bearings, TCCM, transfer case encoder motor, front axle actuator, pigtail connectors and harness for the transfercase, tie rods and tie rod ends, starter, 3/4 o2 sensors, hood release cable, new trans, full pad a rotor kit. I still have a cv boot and a trans cooler line to do, and more than likely both head gaskets. I’ve had the truck for about 2 1/2 years. Love it to death but at this point it’s starting to get a little pricey.

[@toniocavalari6936]

Did you know all this was needed before you bought it, or it needed these things as you owned it ' and time went by ? Sorry for all the questions, but l'm looking at these trucks now in the 2022 gas hikes ' or better yet said " wallet evaporator "

[@dakotapuckett5070]

Just sold my 01 Chevy 2500hd. Had 230k miles. Was the best truck I ever owned.

[@charles400]

What'd It look like

[@tortugalisa4748]

I did enjoy the video very much👍 I'm a visual or hands on learner so how you explained what to look for as you were under the silverado and pointing the areas out, made it so easily understandable💯 Thank you!

[@seanchastain9801]

This is more like a pre trip inspection. 😆 🤣

[@knoxvitela2277]

If I buy one of these with 100k miles would it damage anything if I do fluid changes? Like transfer case ? A transmission fluid change (not flush)

[@johnharrison5098]

can you use shrink wrap to insulated the bigger ground wires to keep them from getting corroded ?

[@Williamcole10]

What if there's only one battery is there not supposed to be two on all of them or is that just for the diesel

[@retroxrama3503]

Hey guys if anyone sees this I’m looking at a 2001 gmc sierra 2500hd has 212k miles on it will the truck still go for a while

[@yellowticket9673]

I'm having weird electrical issues, but I suspect previous owner as oem wire from alternator replaced, but old one left on, power inverter installed, but red wire used to connect both pos and neg terminals, aftermarket stereo with bad install... Will check ground cable though! Thanks for the tips!

[@kevinoconnell8242]

There is a ground terminal under the truck on the drivers side that has a bunch of grounds all meeting up there. Very common rust causes bad grounds and cant figure it outs. CHeck that area if your having issues tough to follow....

[@Jimmmer]

Hey Guys! I'm getting a 2001 2500HD...everything looks mint interior & exterior,not much rust on the undercarriage..its got 84kmiles.Anything I should be weary of in the near future??

[@charles400]

Any luck?

[@trucks_n_tractors_6335]

When he said the cab corners and rockers I went huh my truck doesn’t have those

[@babajideoluwaj5307]

Where do you find truck body paint color at please

[@805r4god]

I owned a 2004 2500HD I love everything about it, except my AC and Heater went out. It's very expensive to repair. Good thing I live in California were its not hot or cold otherwise the best truck I ever had lots of Power

[@stevewilson4503]

Very good

[@papasfunnyfarm9703]

Good vid! I bought a 2500 suburban cheap, but electrical problems galore! It would even stay running when I turned the key OFF! Had to Turn the headlight switch to kill the engine! Hilarious. Redid ground cables, so it runs great now, but still stuck in 4high-auto. And no headlights. I’m going to pull out the fuse box like you suggest. Thanks, man.

[@brayangarcia9605]

What’s the location of the grounds I have kinda same problem

[@insanitology]

What about the 2007 classic? Does that fall under 01-06?

[@MyLifeThai371]

No. In 2007 chevy wen to active fuel management. That is where the truck shuts off some of the cylinders to save fuel. The problem is the valve springs become permanently collapsed and the mechanic has to tear your heads off to replace them. I heard about a guy who already has $13,000 in active fuel management repairs.

[@masterofnone1481]

Gonna test drive one today with 105,000 miles, any tips???

[@alexcruz4640]

Literally the whole video is a tip what a dumb question

[@Hahahahahaha26]

So what if I don’t have a 2nd battery in mine? I bought it like that and don’t see any lines from where it would be.

[@doddgarger6806]

Probably a gas truck they don't need 2

[@edionicio08]

@@doddgarger6806 the truck demonstrated in the video is a gas truck . The diesel duramax does not have a vortec engine cover .

[@edionicio08]

That’s a good question . Never seen two batteries in a 6.0 hd Silverado hmmm 🤔

[@onen453]

I just bought one like that too and it have only one battery, where could it be .

[@george31380]

2 batteries in a gas truck are a factory option if the buyer had planned on hooking up multiple accessories or camper, or inverter for AC electrical current. It was set up to prevent a dead battery for starting the truck just incase the user failed to catch it in time.

[@justinfeazel1997]

My 2001 2500hd has 320k on it and it’s cammed

[@Snake4390]

How about some videos on Nissan Versa Hatchback 2006-2013?

[@zachmartin2]

Anyone burning oil? 02 2500hd 286,000 miles

[@straightouttacomicbook]

Yes sir I am

[@Rick-mp5su]

[@waxman6442]

Hvac problems?

[@ronaldroberts8562]

Stalls when put in revers

[@1AAuto]

+@ronaldroberts8562 We wouldn't be able to diagnose an issue like that here, you may want to have a local mechanic take a look at it. Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c

[@goofball3236]

[@hcaveman6954]

How about more than basic information 🤔. Example rat 🐀 chewing hole in firewall getting into dash and eating the corn 🌽based wire insulation. 🤔!! No new information in this video!☹

[@rabzjatt3590]

S9me the info is new to others

[@LotsOfPaypa]
