1988 Chevy 3500 6.2 diesel 4x4

Does anyone know anything about the 6.2 liter Chevy diesel made by Detroit Diesel?

I am considering buying a 1988 Chevy 3500 4x4 (automatic transmission) with the 6.2 liter diesel from a friend. Truck will have new injectors. No known issues. The truck has little rust (on cab corners) and needs new tires. Transmission was replaced recently with the upgraded version. The asking price is $2,000. Is this a good deal?

Were these good engines?
Were they used on larger commercial vehicles?
I know they were used on Hummers (both military and civilian models)

Is this a good plow truck?
How does it compare in power to the gas versions?


Thanks... any help would be greatly appreciated!

What transmission does it have??
I am guessing it has the Th400, if so it would make a good plow truck, those trannies are pretty stout.

The 6.2 is not a power house by any means, it will feel pretty slow compared to a gasser, but still has plenty of low end power, good for plowing.

The major with problems with these trucks is headgaskets, just check for white smoke or bubbles in the overflow tank.

If the truck runs strong, with a new tranny and everything else is in good condition, I would say 2000 is a fair deal.

You've certainly come to the right place to find a LOT of folks who do.

As stated above, $2000 is not a bad price for a truck like this, but you do need to take a good long look at it. The rebuilt transmission is nice; if it's a Turbo 400 (TH400, THM-400, same thing) then it's a very strong 3-speed, they are very hardy and can handle all the power a 6.2 could ever pass to it, and then some.

A little rust on the cab corners is about par for the course; do be sure you take a look at the frame.

Check to make sure the engine starts well when cold (shouldn't take more than 2-3 10 second cranks on a cold day to start her up). Don't ever use ether to get a diesel started, as it will damage the engine.

Were these good engines?
They aren't super powerful, but they have fairly decent longevity, and with a lot of parts shared with the 6.5L diesel and the 350 Chevy gasser parts are cheap and plentiful.
Quote:
Were they used on larger commercial vehicles?
I know they were used in Chevy step vans, I think that's about as large of a vehicle as you can get this motor to push really.
Quote:

They were also used in the military CUCV, the very heavy-duty pickup trucks the military purchased for moving men and material around outside of war conditions.
Quote:

Is this a good plow truck?
I would imagine it would do fine as a plow truck. Your only concern might be starting at very cold temperatures, but with good glow plugs that shouldn't be a problem. Also the truck should have a block heater installed by the factory, using this 2-3 hours before starting will make it start very easy.
Quote:
How does it compare in power to the gas versions?
It's about comparable to the 305 gasser. Not really a huge amount of power, <150 HP unless you put a turbo on the motor, but much more torque than a 305 at similar RPMs. You won't find yourself unable to get up to speed, but with a 5000 pound trailer and an incline, you might find yourself wishing you had a turbo.

I'm very happy with mine, I think it has plenty of power for my uses (hauling firewood twice a year, dump runs, odd jobs).

You're quite welcome, I hope you get the truck and are happy. Welcome to Diesel Place!

Motor mounts and bellhousing bolts are the same for basically any GM V8 motor. 305 interchanges with 350 interchanges with 6.2 interchanges with 400 interchanges with 454 and so on you get the point.
Makes engine swaps in these old trucks pretty easy!
