1989 GMC Truck Safari

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1989 Safari.

The 1989 GMC Safari sits on a robust body/platform typical of the early late‑model generation, powered by an engine that requires a modest 3‑quart fill of 5W‑30 API oil. In its debut year, the vehicle drew only 21 owner complaints—a relatively low figure for a new truck—though steering issues emerged as the most frequently cited problem, and it was subject to four separate recalls. Over the broader 1990‑2005 span, the Safari’s complaint record peaked in 1995 with 201 complaints, then fell sharply to just five in 2005, indicating that the 1989 model’s reliability profile was solid and that subsequent updates substantially improved consumer satisfaction.

From the factory this vehicle uses OE oil filter 12737092. Note the factory fuel filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter at 7,500 mi; coolant every 30,000 mi. The big-interval services (every 30,000 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 1989 GMC Truck Safari lead in one area — the steering, 4 of 21 reports (19%), well ahead of the next concern. None of this vehicle's 4 recall campaigns target the steering, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 1 of the reports describe a crash and 1 a fire — a small share of the total, but worth weighing against the steering 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.
