Service intervals
| Service | Every (km / mi) | Or every |
|---|---|---|
| Oil & Filter Change | 16,000 km / 10,000 miOr when the Intelligent Oil-Life Monitor indicates — sooner on EcoBoost engines and with towing/heavy loads. | 12 months |
| Tire Rotation | 16,000 km / 10,000 miFord pairs rotation with each oil change. | — |
| Engine Air Filter | 48,000 km / 30,000 mi | — |
| Cabin Air Filter | 32,000 km / 20,000 mi | — |
| Brake Fluid | —Ford specifies every 3 years regardless of mileage. | 36 months |
| Spark Plugs | 160,000 km / 100,000 mi | — |
| Automatic Transmission Fluid | 240,000 km / 150,000 miNormal service. If you tow or haul regularly, a drain-and-fill around 96,000 km / 60,000 mi is cheap insurance on the 10-speed. | — |
| Engine Coolant | 160,000 km / 100,000 miFirst change at 160,000 km / 100,000 mi or 6 years; every 80,000 km / 50,000 mi or 3 years thereafter. | 72 months |

Confirm the grade and capacity against your owner's manual before servicing — figures can differ by trim, drivetrain and market.
What each service does
Oil & Filter Change
Ford's oil-life monitor tracks engine conditions and calls for a change up to 16,000 km / 10,000 mi or once a year, whichever comes first.
Tire Rotation
Rotating tires with every oil change evens out tread wear across all four corners.
Engine Air Filter
A fresh air filter keeps the engine breathing and protects fuel economy. Ford schedules it around 48,000 km / 30,000 mi.
Cabin Air Filter
Filters dust and pollen from the cabin air. Ford lists replacement around 32,000 km / 20,000 mi.
Brake Fluid
Brake fluid absorbs moisture over time; Ford replaces it on a 3-year clock to keep a firm pedal.
Spark Plugs
Ford's plugs are rated for about 160,000 km / 100,000 mi. Worn plugs cause misfires and hurt economy.
Automatic Transmission Fluid
Ford's normal-service interval for the automatic transmission fluid is long, but severe use warrants earlier changes.
Engine Coolant
Ford's orange coolant carries a long first interval, then shorter changes to maintain corrosion and freeze protection.
These intervals are drawn from the 2021 Ford Bronco's manufacturer maintenance schedule for normal service. Your vehicle's owner's manual remains the final authority, especially for "severe service" conditions like towing, short trips or dusty roads. BoxKitz links you straight to the manufacturer's manual and live recall data once you add the vehicle.
