Hello Ford community I need a maintenance plan for my 2021 Ford F 150.

How many miles are on your truck? What Motor is in your truck?

3,5 Eco ca. 89000 km

I got this from Chat GPT

Got it! Here’s a practical, easy-to-follow maintenance plan for a 2021 Ford F-150 with the 3.5L EcoBoost at 89,000 km. (I’ll stick to km; halve the intervals if you drive in “severe” conditions—frequent towing/hauling, lots of idling, off-road/dusty, extreme temps, or mostly short trips.)

What to do now (at ~89,000 km)

• Oil & filter: If it’s been ≥16,000 km or 1 year (or the Oil Life Monitor says so), change it. Use oil that meets the Ford spec in your owner’s manual and a quality filter.
• Tire rotation & balance: Rotate now; check tread depth and even wear. Align if you see edge wear or any pull.
• Engine air filter: Replace if dirty or older than ~48,000 km.
• Cabin (pollen) filter: Replace if older than ~32,000 km or 1–2 years.
• Spark plugs: These are typically due around 96,000 km on EcoBoosts—plan to replace soon (within the next 5–10k km). Use OEM-equivalent plugs gapped to the spec on the under-hood label.
• Brake system: Replace brake fluid if it’s ≥3 years old (a 2021 is due). Inspect pads/rotors, slide pins, and parking brake.
• Cooling system: Inspect hoses, clamps, and coolant strength; top up with the correct Motorcraft-spec coolant. Full coolant replacement generally at ~160,000 km or 10 years (whichever comes first).
• Transmission (10-speed): Not always “required” by the book yet, but a preventive drain-and-fill around 96–120k km is wise—especially if you tow/haul or drive in heat.
• 4×4 drivetrain (if equipped): Inspect transfer case & diffs for leaks and fluid condition. If you tow/off-road, consider fresh fluid around 80–100k km.
• Drive belt & pulleys: Inspect for cracks/noise; replace if worn.
• Battery: Load-test; clean terminals.
• Turbo & intake checks: Inspect charge pipes/clamps for oil seepage or loose couplers; check airbox seal; look/listen for wastegate/boost leaks. Clean MAF/throttle body only if symptoms (rough idle, codes).

Ongoing schedule (normal service)
Every 8–10k km (at each fuel service or two oil changes)

• Check fluids (engine oil, coolant, brake, power steering if applicable, washer).
• Visual underbody/axles/boots/hoses for leaks or damage.
• Inspect brakes & tires; adjust pressures (incl. spare).

Every 16,000 km or 1 year

• Engine oil & filter
• Tire rotation (cross-rotate per Ford spec)
• Full inspection: lights, wipers, HVAC performance, suspension joints, steering components.

Every 32,000 km

• Cabin air filter
• Inspect brake pads/rotors more closely; clean & lube slide pins.
• Check alignment if any uneven tire wear.

Every 48,000 km

• Engine air filter
• Inspect fuel system (lines/fittings) and evap hoses.
• Inspect front/rear wheel bearings for play/noise.

96,000 km

• Spark plugs (all 6)
• Consider transmission fluid drain-and-fill (strongly recommended if towing/hauling or lots of city/heat).
• Thorough cooling system inspection (hoses, water pump seepage, heater performance).

120,000 km

• Brake service check: consider replacing pads/rotors if nearing limits; refresh brake fluid if >3 years since last change.
• 4×4: If used off-road/towing, change transfer case and differential fluids now if not done earlier.

160,000 km or 10 years

• Engine coolant replacement (use the correct Motorcraft spec; fully bleed system).
• Rear differential and transfer case fluid (if not done earlier).
• Inspect accessory drive belt—often replaced around this mileage.
• PCV system check; replace valve if specified or if performance issues.
• Thorough inspection of turbos/charge air cooler (CAC) hoses; clean CAC if there’s excessive oil pooling and drivability symptoms.

Severe-duty adjustments (if applicable)

If you tow/haul frequently, idle a lot, drive dusty roads, or see extreme temperatures:

• Oil & filter: every 8–12k km.
• Air filters: inspect each oil change; replace sooner if dusty.
• Transmission/4×4 fluids: service around 60–80k km.
• Brake fluid: every 2–3 years.
• Wash the radiator/CAC fins gently more often; keep mud/bugs off for better cooling.

Tips specific to the 3.5L EcoBoost

• Always use the correct oil spec and viscosity listed on your oil fill cap/owner’s manual; the right oil helps turbo health and timing chain longevity.
• After heavy towing or long climbs, give the engine a minute of light-load driving before shutdown to let turbos cool.
• Keep the air intake system sealed (properly seated air filter and clamps) to protect the turbos and MAF.
• If you notice rough cold starts, misfires under load, or poor economy near 90–110k km, suspect spark plugs first.

Thank you...

You order the maual from ford on line.

Or just download the manual: https://www.ford.ca/support/vehicle/f150/2021/owner-manuals/
There is also a maintenance schedule for the larger “milestones “ in the Ford Pass app in the “service” section.
I’d be wary about relying on ChatGPT’s advice. Every 16k for an oil change is the upper end in the manual (for all engine packages). I wouldn’t ever wait that long, but especially with a 3.5 EB. Personally, I use an 8K km interval.

Thank you very much..
