2002 Cadillac Seville

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2002 Seville.

Body PASSENGER CARTransmission Automatic 4-spd

The 2002 Cadillac Seville is a passenger car fitted with an engine requiring 8 quarts of 5W-30 API oil and paired with an automatic 4-speed transmission, carrying EPA ratings of 16 mpg city, 25 mpg highway, and 19 mpg combined. Among the 1990–2004 model run, the 2002 model logged 68 owner complaints—well below the 1996 peak of 131 yet above the 2004 low of 17—with suspension flagged as the top complaint area and two recalls on record. That complaint volume places it roughly in the middle of the Seville’s reliability arc, meaning a researcher should expect a moderate issue history rather than the generation’s best or worst year.

Fitment & sizes

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

From the factory this vehicle uses a BCI 79 · 800 CCA battery, OE oil filter 12731179. Note the factory fuel filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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.

Service quick specs OEM factory data

Capacities, torques and tune-up values from the factory service manual.

This engine holds 8 qt of 5W-30 API engine oil, DOT 3 brake fluid. Torque lug nuts to 100 ft-lbs, the oil drain plug to 15.0 ft-lbs. The firing order is 1-2-7-3-4-5-6-8. Note the cylinder-head bolts finish on a torque angle (torque-to-yield) — they stretch permanently and should be replaced, not reused, during any head service.

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.

From 1990 to 1996 complaints rose steadily, peaking at 131 in 1996, then fell to 40 in 2000 and rose again to 53 in 2001 and 68 in 2002. Recalls remained low, averaging about two per year except for 1991 and 2001 when none were recorded, with 2002 showing two recalls. Investigations declined after the mid‑1990s and were zero from 2000 onward, including 2002. Technical service bulletins increased sharply after 1999, reaching 450 in 2002 and continuing to rise through 2004. Thus, 2002 sits in a phase of lower complaint frequency than the 1990s peak but with a growing volume of TSBs, indicating more documented service topics rather than a spike in defects. Given its modest complaint count, absence of investigations, and average recall level, the 2002 Cadillac Seville is a reasonable used‑car choice provided its service history addresses the numerous TSBs.
