2007 Isuzu Ascender 2WD

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2007 Ascender 2WD.

The 2007 Isuzu Ascender 2WD is recorded here only under its model-year, name, and two-wheel-drive designation, with no accompanying details on body style, platform, or powertrain in the supplied data; that absence leaves no standout specifications to highlight, and because the source material offers no reliability information, this model year cannot be situated within any broader durability context for the Ascender line, reducing the entry to a basic identifier rather than a technical reference.

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.
