1998 Isuzu Oasis Service and Repair Manual

A bigger engine arrived for 1998, when the Oasis switched to a 2.3L SOHC VTEC inline-four rated at 150 horsepower, replacing the earlier 2.2L. The van kept its four hinged side doors, fold-flat third row and S or LS trim choice. That engine change alters ignition, timing belt and emissions specifications, so earlier-year data will not fit. This factory service and repair manual is built around the 1998 Oasis, with procedures, specifications, torque values, wiring diagrams, diagnostics and maintenance schedules for the 2.3L and its four-speed automatic.

Known issues on the 1998 Oasis. Four recalls are on federal record. They cover lower and upper front ball joints that can wear out early and separate, ignition switch contacts that can degrade from high starting current, and driver airbag inflators that may absorb moisture and rupture or underinflate in a crash. NHTSA has also logged 10 owner complaints, most often about the electrical system and the powertrain. Suspension, ignition switch and airbag module procedures in the manual correspond to each campaign.
