I'm looking to buy another truck. If I"m looking at one of these trucks what should I pay attention to? Other than the standard body, frame, suspension issues.
Here is how I evaluate one of these beasts. First (After hood is open) Check coolant level, oil level etc. Look under the rig for signs of major leaks of oil coolant fuel etc. Spin the engine without allowing the glow plugs to heat. The starter sound should be even with an even za za za...
I would guess the newer trucks might need more technology to inspect say something like a scanner that can measure balance rates of injectors???
With the expense of the newer injectors and IP's etc I think I may want some receipts or proof of maintenance.
....For the last 25 years the first 100K miles is dang near maintenance-free but reaching 200K-300K takes some appreciable maintenance costs.
Used Duramax is all about the injectors. Have they been replaced, exactly which ones matter. Throwing a computer on to check them out is a smart idea if possible.
