1998 Pontiac Sunfire

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

Body PASSENGER CAR

The 1998 Pontiac Sunfire is a compact passenger car that requires 4.5 quarts of 5W-30 API engine oil, and its reliability record, drawn from owner complaints spanning the 1991–2005 model range, places it in a middling position: with 128 total complaints and 7 recalls, it falls well below the peak trouble year of 1996 (237 complaints) but far above the near-flawless 1991 model (just 1 complaint), while the most frequently cited issue involves the engine and cooling system.

Fitment & sizes

Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.

From the factory this vehicle uses a BCI 75 · 525 CCA battery, OE oil filter 12731172. Note the factory fuel filter and front wiper blades are now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 every 7,500 mi; 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.

Federal complaints and recalls for this generation escalated sharply after 1994, cresting at 237 complaints and 10 recalls in 1996 and remaining elevated at 225 complaints and 9 recalls in 1997. The 1998 model sits on the downward slope of that curve with 128 complaints and 7 recalls, improving on the two prior years yet still above the generally lower complaint and recall volumes seen from 1999 onward, when recalls dropped to as few as 1 by 2005. Investigations fell to zero in 1998 after three consecutive years of active probes, and its 108 technical service bulletins track closely with 1997 and 1999 but are far below the 375-plus counts that begin in 2000. Owner reports for 1998 cluster in Engine & Engine Cooling (24), Air Bags (11), Steering (11), and Electrical System (11), with 14 crash-related and 3 fire-related complaints, though the data does not specify root causes. Because it escapes the generation’s peak defect activity but remains above the lower-incidence later years, the 1998 Sunfire is a decent compromise—preferable to a 1996 or 1997 example, though buyers seeking the cleanest federal record in this generation should look to 1999 or later.
