Known issues on the 2000 T7500. Nothing is on the federal record for this model year — no recalls and no owner complaints filed with NHTSA. What a shop is left with is the ordinary work of keeping a working truck earning, and that is what the manual documents: injection and air handling on both diesels, cooling system service, brake and chassis procedures, the torque values that go with each of them, and wiring diagrams with diagnostic sequences for the circuits behind the dash warnings.
