1993 Isuzu Trooper Service and Repair Manual

Two doors returned to the lineup in 1993, when the Trooper RS joined the four-door S and LS on a wheelbase 17 inches shorter. The RS shared the LS's twin-cam 3.2L V6 and equipment, while the S kept the single-cam 3.2L. Different wheelbases mean different driveshafts, brake lines and body data, so the model year and body style both matter. This factory service and repair manual covers the 1993 Trooper with procedures, specifications, torque values, wiring diagrams, diagnostics and maintenance schedules for every version.

Known issues on the 1993 Trooper. Two recalls are on federal record. One addresses an accelerator cable that can stick, keeping engine speed from falling when the pedal is released; the other addresses a camshaft seal end plug that can dislodge and leak oil. NHTSA has also logged 40 owner complaints, most often about the engine and cooling system and the tires. The manual's throttle linkage and engine sealing procedures cover both repairs.
