Help!!! Need inside scoop on 2000 GMD 3500 Diesel truck

    I'm looking at purchasing a 2000 model GMC 3500 series sweeper that has 155000 miles on the front engine and a new rebuilt back motor.

    Can any of you tell me if the GMC 3500 has any known trouble areas? This is a Diesel/Diesel unit, the rear engine is an Isuzu with about 180 hours on it. Can I expect to get 200K or so miles out of the front engine and trans before it needs a rebuilt motor and or trans. How much does it cost to rebuild the front Diesel engines in these trucks.

    I know, lots of questions.....please help. I need to go to Florida to see this truck this week and I'd like to know if there are anythings I should look out for?

    BTW it is a Elgin AIr Cub. He is asking 15000.00 for it. It looks very clean in the pictures the seller sent me.

    Is it a cab over or a pick up?

    In my opinion if it's a 6.5 L Diesel from what I have seen your lucky it made it too 155,000 with out blowing up! I have a friend who is a mechanic and the regularily have seen the 6.5 blow up between 60,000-100,000 miles on trucks that are in mint shape and not used for work. But who knows if it's in good shape it could be a decent truck, I am not up on the sweeper end of things!

    First I've heard of that. The 6.5 was a good engine. Not a ton of power but it's longevity and durability was great.
  5. My bro had a '94 Suburban with the TD 6.5L.

    Highs: decent mileage...16.5 or so on highway doing 70.

    Lows: Mysterious "chug" at hard acceleration, and cost of repairs. Admittedly, the truck looked as though it was not the best maintained. BUT, at around 140K, head gasket or something went. Was gonna be $4500 to fix whereas a BB chevy woulda cost 1/4 of that!

    From the fact that diesel repairs are costly (arguably less prone to repairs I guess), I'd stick with gasoline!

    Around here most sweepers are Diesel. They get better milage than big gas engines and will run for more miles if taken care of proprely. I should be going there to see the truck in person this week.

    Thanks for your replys,

    6.5 is fine, although several completely uninformed people here and other forums have convinced themselves they are no good. I worked in a big garage for 10 years and never saw one blow up. They are known for the pump mounted driver failing, which is normally misdiagnosed as a injector pump failure. The pre-97s had a poor cooling system design that resulted in head gasket failure, but 97-up fixed that. Mine has 155k on it only real trouble has been PMD failure at 150k (still not too bad) and I replaced the crank sensor last year, was running a little rough. I beat the crap out of mine, tow 11k and push a Blizzard 810. Plenty of life left in her.

    Thanks for the info, to both of you.

    What is PMD stand for? Is it an expencive repair? I don't mind spending money on mainence and repairs, I just don't want to buy anything that is going to cost me 5 grand 1 month into ownership. All in all I'm told by a trusted source that he runs a good operation with 3 locations each with their own full time mechenics to maintain the fleet of 20 sweepers. However I can see in one of the pictures he sent that one of the front tires don't have even tire wear compaired to the other one. It most likley will need some front end work, I'll also check for any frame damage in the front end. We'll see.......

    pmd stands for pump mounted driver. Its a small electrical ballast device that mounts to the side of the injector pump. Can fail due to high heat in the intake valley, however they do normally last over 100k, so apparently they are designed to work in a hot environment, at least for a few years. It is recommended to put them on a remote mounted heat sink cooler with an extension harness. I put mine on the fenderwell, was way easier than taking the old one out. Some guys get crazy and put them outside the engine bay for maximum cooling, but I think that's too far in the other direction. They list for around $420 usd, I bought mine on ebay new for $250.

    Thanks for the reply,

    I'm finding more about this truck every day. Local Chevy dealer said it should have a 6.2 Turbo Diesel motor in it. The dealers service department said they have been very good engines without any major troubles.

    As I understand it the 6.2 was the non-turbo engine GM used until they replaced it with the 6.5 turbo in the early 90s, 93 I think.

    6.2 is pre 6.5. They are wrong. Although, there is nothing wrong with the 6.2 either.

    Thanks for the replys guys. Non Turbo is probably slower pick up 0 to 60. But thats ok, it will be a work truck driven in the night time [9 PM to Dawn] when there is very little traffic to deal with. I'm more woried about reliability and fuel mileage rather than speed. I'd like to seee this thing run for 250 to 300K miles before it needs a rebuild. Do you think thats possible? The guy at the Chevy dealer said It should run that long with no sweat, however he thought it ws a Turbo and you are telling me it isn't!!!

    Does this motor have a name like Powerstroke [Ford?] or something like that? Sorry for the Newb questions but I have never owned a Diesel.

  15. Man...either someone put that engine in (6.2) themselves or you got some bad information somewhere. In 2000, it should be 6.5...unless maybe "medium duty" trucks or something where still kicking around with the old 6.2.

    I thought all the 6.5s in trucks were turbo too. I do know there where non turbos available earlier (95?) in regular, 2dr Yukons etc...

    I'd recommend checking out www.dieselplace.com They have dedicated forums for both 6.2, 6.5.

    In a 2000 the engine is almost definitely a 6.5TD. By that time (post-'97, as already mentioned) most of the defects had been worked out of the engine, and I think that was the only diesel available at that time. There was no longer a neew for the 6.2 or non-turbo engines, especially since they were not the highest powered. Dodge and even Ford had more power, so GM was not likely to install a wimpier engine.
    FWIW, the 6.5TD can be souped up easily to about the same power levels as the Dodge and Ford engines at the time. Of course, once the Duramax came out the diesel horsepower wars started, and now power output is about twice as high.

    Is this a pickup cab and chassis, a cab over or a P chassis? The P chassis were the only ones using a 6.5 non turbo at that time

    It figures, I got the info from a Chevy dealer. I talked with a service guy who apparently don't know what he is talking about.:realmad: You would think you would be able to get correct info at a dealer!!:realmad:

    Here is a picture of the truck. I thinlkk they build them off of the dually pick up platform but I'm not sure.

    Thanks again for all the responces!!

    So its probably had fairly easy life, putting around at low speed, never towing or plowing, and I don't know how much that weighs but it doesn't look like anything that would overload the chassis.
    Nice mirrors!
