1999 Isuzu Trooper Service and Repair Manual
Few changes marked the 1999 Trooper, which continued as a single S model dressed up through option packages such as the Performance Package, now with fog lamps and available gold trim. Power came from the 3.5L DOHC V6 introduced the year before, with manual or automatic transmissions and four-wheel drive. This factory service and repair manual covers the 1999 Trooper with procedures, specifications, torque values, wiring diagrams, diagnostics and maintenance schedules for the 3.5L engine, the transmissions and the four-wheel-drive system.
