1995 6.5 liter Suburban

[maxstr1]

Hey All,

I am looking at getting a Diesel Suburban with a 6.5 and 189000. Can someone who has had a rig with the 6.5 hit me back and let me know what how long i can expect this thing to last? Any know problems with them?

Any info I can get I will appreciate.

Thanks,

Max

I have found weakness in the following areas
1) pmd pump mounted driver the black electrical box on the injection pump.
most of the injection pumps replaced on this motor are because of the pmd failure (NOT THE INJECTION PUMP!) usually the motor will start up and die shortly after. A remote mount kit can be purchased on Ebay.

2) Timing chain. Driving the injection pump with a Chain is very hard on the chain gear kits are available to get rid of the chain.

3) Harmonic Balancer which leads to rods escaping from the Block just keep on top of it and replace at any sign of wear .

After these are taken care of the 6.5 can be a reliable fuel efficient
vehicle it can even be hotrodded but dont expect a whole lot out of it .
Hope this helps Rich $.02

As far as miles before rebuild it would depend on how the engine was taken care of I have heard of 1 with 325000 miles I dont think this is the norm though. Our burban has about the same miles on it as the one you are looking at but we bought it planning to swap the engine to a cummins. 97 up have a better cooling system. Rich
