1998 GMC Truck Jimmy 2WD

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1998 Jimmy 2WD.

The 1998 GMC Jimmy 2WD is a two-wheel-drive utility vehicle within General Motors' light-truck lineup, factory-specified with a 5-quart engine oil capacity and 5W-30 API viscosity as its standard service parameters. Within the Jimmy's reliability record, this model year accumulates 260 total owner complaints with Visibility emerging as the most frequently cited problem area, alongside two recalls on file. For researchers, that profile positions the 1998 model as a documented but middling entry in the nameplate's history—neither the strongest nor the weakest year, but one whose complaint pattern and recall count define its standing within the broader Jimmy story.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 100,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 1998 GMC Truck Jimmy 2WD lead in one area — the visibility, 65 of 260 reports (25%), well ahead of the next concern. None of this vehicle's 2 recall campaigns target the visibility, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 23 of the reports describe a crash and 3 a fire — a small share of the total, but worth weighing against the visibility pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
