2026 Ford F-250 Super Duty
Reliability tier: verified - see /disclosure/
Engine: 7.3L V8 Gas (Godzilla) (Ford Godzilla, 7.3L), 2v
OHV 2-valve V8, cast-iron block/aluminum heads, sequential multiport fuel injection (no DI, no HPFP), VCT, no cylinder deactivation; 10.5:1 compression; 430hp @ 5,500 and 485 lb-ft @ 4,000 lb-ft in the pickup lines; TorqShift 10-speed (10R140) behind this engine (context only - engine platform). The 2023 SD refresh made the 6.8L (same Godzilla family, short-stroke) the standard gas engine; the 7.3 remains the optional gas engine on the pickup and chassis-cab lines. Catalog-coverage note: the Ford dealer catalog's model-year pages ends at 2025 as of 2026-09-29 (no 2026 parts-list pages in the sitemap); 2026 config carries no catalog-backed parts rows yet.

Platform recipes (4)
- Cooling service for the 7.3L Godzilla: pressure-test, then water pump and thermostat as wear items, pump numbers split by year (mode fm-gz-cooling-service)
- Exhaust manifold leak repair for the 7.3L Godzilla (mode fm-gz-exhaust-manifold-leaks): cold-start tick and soot tracks at the flange
- Ignition service for the 7.3L Godzilla (mode fm-gz-ignition-service): 16 plugs on the 2v SOHC V8, one coil per cylinder
- Tapping that follows one cylinder on the 7.3L Godzilla: check Ford program 24B27 first, separate the oil pump drive gear (lower front, 2020-2022) from the valvetrain, then lifters and the cam lobe (mode fm-gz-lifter-cam-wear)
