Older diesel ?
 

Looking at a possable tow vehicle, 1991 Suburban 2500 with a 6.2 diesel , 150,000 miles. Any pro's or con's on this for towing ?

Thanks

Lotsa torque, no H.P. will get you going, but won't keep you there.

Also good for breaking cranks and harmonic balancers

Bud,

If you are looking to tow with an older diesel pick up truck I would recommend a ford F350 with a 7.3 liter diesel. They were available from 1997 to 2002. They are real reliable and have lots of power. If you can find one with reasonable miles on it you will have a great truck. I had a 99 and loved it. I now have a 2005 chevy with a duramax diesel. It tows well also.

I've got a couple of friends who have or had those. They are not the best diesel out there, but good service can be had with proper care. The later 6.5 is better. A close friend had a 97 with a 5 speed for 9 years, and about 450K miles. The 5 speed gave some trouble, but the engine was fine. It had 4.10 gears, we put a Flowmaster on it, took the converter off, and put a K&N filter in it, and it ran strong. We pulled a 32' enclosed goose neck with a Pro Street car in it for about 1/2 those miles, and rarely got under 70MPH, it got about 15 MPG. Far as I know, the truck is still running.

Bud,
If memory serves me correctly those engines had injection pump problems.You would be better off with something newer. If you can step up to a new Duramax I know the dealers are selling them at a loss.

Alot of people have swapped the 5.9 cummins in the chevy trucks and burbs.

6.2 was a fairly reliable piece for most of the farmers around here, however they never hooked to a trailer and tried to travel any distance either. They suffer some common ailments , Inj. pumps glow plugs damper breakage Ect. not in my opinion worth the risk if you're looking to do some traveling with it. These were in my opinion about the worst attempt at a diesel engine by the big 3. Save yourself alot of trouble and get a 7.3 powered ford or a mid 2000 G.M. duramut. Can't say anything good about the Dodge except Cummins does make a very good diesel engine. Joe

I have had both 6.2 and 6.5 in my tow vehicals put injector pumps on both cylinder heads on the 6.5 , they both are underpowered and if you tow a large trailer you will have overheating problems my 6.5 would run about 240 degrees towing my gooseneck i would stay away . my duramax will pull with no problems
