2001 Isuzu Trooper Service and Repair Manual

Isuzu marked its 85th year with a special edition of the 2001 Trooper, while the core S, LS and Limited lineup carried on. All used the 3.5L DOHC V6, with a choice of rear- or four-wheel drive and Torque-On-Demand on automatic 4WD models. The truck was nearing the end of its run, so parts sourcing increasingly depends on accurate data. This factory service and repair manual covers the 2001 Trooper with procedures, specifications, torque values, wiring diagrams, diagnostics and maintenance schedules for every configuration.

Known issues on the 2001 Trooper. One recall is on federal record. It concerns Torque-On-Demand automatic 4WD models, where engine compartment components can move in some high-speed frontal crashes and create a potential for fuel leakage. NHTSA has also logged 29 owner complaints, most often about the powertrain and the engine and cooling system. Fuel system routing and engine compartment procedures in the manual help confirm the remedy.
