i got a real good deal on it, so i bought one. only thing is its got 200,000 miles on it. so what do i need to check to keep this thing up and running for another few years?

 

no help?

 

Just make sure the transmission is up to par and you will be fine. 200,000 miles means the motor may finally be broken in. you can expect 1/2 million to 1 million easily out of these 5.9's. enjoy the truck. I would do a full fluid change, Trans, diff, transfer case, oil, coolant, power steering, even brake if it looks bad. and use quality fluids. Change the fuel filter and air filter. you will find this to be a great truck.

 

X2, keep up on your fluid changes and regular maintenance and you should be just fine!

 

I'm new to diesels but I've bought many cars, new and used.

I'd put it this way. Think of it like CSI. If you change everything now, then you lose a lot of evidence of issues that may exist. I think the advice given is great, but I'd do it sequentially by priority.

* Check oil in the tranny and motor. Is it clean? Have it analyzed if poss. What's the service history?
* How does the coolant look? Has it been checked for combustion by-products? (long story)

I'd start by checking all levels, replacing any obviously worn fluids, then give it a real drive of at least 50 to 100 miles on the highway (in the hills if poss) to reveal any issues. What's the longest you have driven it continuously?

Also, you might want to go to the Dodge dealer to get a "vip summary report". I don't know if they normally charge for it but I think if you sweet talk them you'll get it. Basically go in, say you want to find out all the installed options on the unit (can be VERY interesting) and see what she has. And that will have service history at that dodge dealer (and I think all dodge dealers?) in the print as well as the original owner, etc. GOOD stuff.

Oh and get a Carfax and check the belts for cracking.

Let us know what you find out!
