chevrolet suburban 6.5 diesel for towing?

Hi everybody,
I have a 68´Overlander, wich has been complety restored and with a total weight of 4400lbs, I have an old firetruck for towing , but is very slow, and one guy offered me to change my truck for a 1997 suburban 6.5 diesel...
Will be the suburban safe enough for towing?

Any page where I can find towing fittings?

Thanks!!!

The Suburban is arguably the most stable trailer towing vehicle currently available. Is the diesel engine turbocharged or normally aspirated?

97 6.5 will be turboed. I use my 97 to tow my 34 ft. close to 100,000 miles.

That era 6.5 is a pretty darned good engine. The only really common issue (if maintained properly) was the optical sensor in the injection pump. If it has been replaced as recently as....maybe 2003 or so, the current pump is probably OK. I haven't been invloved with any 6.5s for a long time now as they have cycled out of most fleets, but the pumps were beginning to get to be hard to find by 2007 or so. Maybe an aftermarket company has picked up on them since.

Yes, very good towing vehicle... But I am biased

check out The Truck Stop for a great community of folks that can help the 6.5TD to its full potential.

The biggest issue is the PMD, which is a GM design flaw. Once the PMD is removed from the IP and relocated to the front bumper area they are a very reliable engine. Keep your grounds clean as well.

After the normal preventive maintenance, I recommend a better turbo and exhaust as the stock system is very restrictive. The result is more power and less stress on the engine resulting in lower EGTs.

Feel free to PM me if you have any 6.5 questions!

I would also agree that the 6.5 is a very capable engine although I am biased also. I would definetly relocate the pmd as mentioned earlier and keep the engine serviced and you will be a happy camper.I have owned my 94 chevy 6.5 for 7 years and it has been good for me and I also tow a 34ft trailer.

I forgot that this link was not in my signature.

Some ideas for your 6.5

The oil pressure switch and FSD are must modes.
The oil pressure switch is a 1 amp capacity switch switching a 4 amp fuel pump. The FSD will cook itself in 50,000 miles if left on the pump.
