What to look for when buying a Used Duramax *wish I knew this sooner*

Don’t buy a 20k truck in the North. If your spending that kind of money, buy a one way plane ticket to Texas and get a truck with no rust. IMHO It’s what I do.

[@netprowlerp]

Amen Brother. Those northern trucks are soooooooo rusted out.

I guess you forgot about the crazy flooding that's happened in Houston and other parts of Texas over the last few years. Fuck Texas, I'll got to Arizona or New Mexico.

[@Buzzliteb33r]

With exception to Idaho/Montana/Washington and Oregon. Salt is rarely used up here iv purchased dozens of vehicles up here with little to no rust. But a good rule of thumb is to buy in the south vehicle tend to be cheaper in cali and Texas anyway.

I know nothing about Duramax...much less any diesel truck. I would like to find something within my "old man, retired, and poor" budget to pull my 5th wheel with. I currently have a 6.0 GMC that will do the job on the flats but when into any hills, she will grunt. (the Alison trans is a good option too) I definitely need to watch more of your videos to understand what LGBTQ, LLY, BMT, XYZ, and all the other Duramax acronyms mean.

Collapsed upper radiator hose most of the time is a coolant tank cap getting gummed up with crusty dexcool. Soak it in hot soapy water for a while and rinse with hot water then blow it off with some compressed air. Happend to me in my LLY and LB7 this fixed the problem. Definitely could be other problems also stated in the video but always start with the easy stuff first👍🏼

I realize this is an older video, 4 years at this point, but A LOT of great information. I just recently purchased a 2019 2500 HD L5P crew cab, and man do I love this vehicle. It is GM Certified less than 75k miles. I work on the big rigs for Kenworth, but have never personally owned a Diesel engine myself, especially not a Duramax, until now. And man, after watching a few of your videos, I’ve learned 1 thing - I’ve got A LOT to learn lol. I appreciate you, your honesty, and the time you’ve spent making these videos. Thanks bud.

[@bf6159]

Additional considerations: #1 check the title and find out where it was prior to the respective lot you are browsing... many trucks get shipped around the country, flood vehicles are everywhere! #2 don't drive anything off a lot with promises, even if put in writing, ensure the issues are corrected prior to accepting any vehicle. #3 blistered paint usually means body rot, rust and blistered paint is a definite sign of serious body issues - it's often cheaper to replace the entire bed of a truck VS repairing a portion of the bed. #4 being many folks don't have personal diagnostic systems... take a test drive and stop by an auto-parts place that does free scanning, have them plug it in. And...don't purchase a used Duramax from Byers Chevrolet in Columbus Ohio. I invested $35,000.00 in a Chevy 2500 HD with 98000 miles and a clean interior... in less than a year, by their estimate, $9900.00 in needed body repair for what they cited as surface rust on the bed, rockers, and corners, in addition to numerous electrical issues, issues they claimed didn't exist at the time of purchase.

[@kfstreich4787]

One more thought, the transfer cases on some trucks have a pump rub issue, this will shut you down in a hurry! If it leaks, or you get a strange oil splatter on your tailgate take preemptive action before the internals self destruct!

[@mylink2u7]

Also check the hours by pressing odometer button instead of the miles. A lot of these idle in the oil field all day 24/7.

The VIN is the indication to use on where a truck was actually made. Starts with a "1, 4 or 5", U.S.A. 2 is Canada, and 3 is Mexico.

*UPDATE: i now own a 2006 Dodge Ram Mega cab 2wd SLT bought it for a tow rig still have my Escalade EXT everything is paid for and titles all in my safe. the Dodge had 172,000 miles on it when i purchased it in Oct, now has 174,000 and yeah if you fold the back seat down flat to the floor by using the release n the side of the seat at the floor you can put a full size maybe even a queen mattress in there. might come in handy in the event you can't find a hotel somewhere one night. the guy i bought mine from wanted $14,250.00 I test drove the truck came back and pulled a Richard Rollins on him. (MEANING) i walked in threw the keys back at him and asked him "so how much is this $5,000.00 truck going to cost me? Now we both know that the truck is worth at least twice that specially since there is no rust here on our trucks and this truck has never been out of the state it sold new to a guy in Knoxville through ORNL credit union and was reposessed in August last year 2018, I purchased it from a lot in Glasgow KY about an hours drive North East of me. I ended up paying $9,000.00 even for the truck. of course then all the LED goodies started getting ordered and installed and i may have a total of $9,500.00 total tied up in it now with replacing upper and lower ball joints and such. love the motor, can't stand what they wrapped around it with the exception of the mega cab bit*

I'm not sure if you go over it later in the video but look into the duramax injector cleaning procedure with gm upper end and injector cleaner, this is the system where you disconnect the fuel system and idle off a fuel jug with cleaner and half a gallon of diesel, I did this on my lbz and it improved idle as well as eliminated black smoke at idle and full throttle.

I bought an 05 GMC Sierra 3500, crewca long bed WT, 158k miles for 18k with the iffy aftermarket warranties. Truck was 14,999 beforehand. I checked as much as I could before I bought, excepted there to be a wee bit of work as it was used and came off a ranch. Ran great, drove great checked exhaust etc, as mentioned for color and all. After 4 months the injection pump completely took a crap. Luckily the iffy aftermarket warranty will cover it, but nothing else. So still looking at 5k out of pocket. It is my first personal Diesel, so not super stoked but staying positive.

Dan Makin On my gas trucks in the past I would always change my oil every 3/4K miles. I let the Duramax go 5/6k miles (deleted) so it's about the same cost really.

There’s a lot to check for! But hey if you get one that was maintained well, it will last forever. Exterior- Check the frame, especially where the spare tire goes. The bed rails and feel up behind the fender wells. If the trucks high enough try to poke your head up under there. The obvious cab/rockers. If it’s a white truck, check for paint flaking, GM did a horrible job. I believe there was a recall back in the day.
