2025 Ford F-150 — Coolant Capacity & Type

The 2025 Ford F-150 holds roughly 12–20 quarts (11–19 liters) of coolant in the engine cooling system, depending on engine, cooling package, and whether it’s a hybrid with multiple loops.

Quick answer

• Total cooling system capacity: About 12–20 qt (11–19 L), engine- and package-dependent (see table below)
• OEM coolant spec: Motorcraft Yellow Antifreeze/Coolant (yellow color), phosphated OAT (P‑OAT), meeting Ford spec WSS‑M97B57‑A1. Do not mix with earlier Orange/Green coolants
• Mix ratio: 50/50 with distilled water if using concentrate; pre‑diluted 50/50 Motorcraft Yellow is acceptable

Capacity by engine option

Exact capacity varies with radiator size, Max Tow/Heavy‑Duty packages, cab/box configuration, and auxiliary coolers. Use these as planning ranges and verify on the under‑hood decal or service info for your VIN.

• 2.7L EcoBoost V6: ~12–14 qt (11–13 L)
• 3.5L EcoBoost V6: ~14–16 qt (13–15 L)
• 5.0L Ti‑VCT V8: ~14–16 qt (13–15 L)
• 3.5L PowerBoost Hybrid (engine loop): ~16–18 qt (15–17 L)
  • Hybrid electronics/transmission loop (separate): often an additional ~2–4 qt (2–4 L)
• 3.5L High‑Output EcoBoost (Raptor): ~16–18 qt (15–17 L)
• 5.2L Supercharged V8 (Raptor R): ~18–20+ qt (17–19+ L)

Flush interval

• Normal service: Up to 10 years or 200,000 miles (320,000 km) on Motorcraft Yellow factory fill. Inspect annually and maintain freeze/boil protection and pH
• Severe duty (frequent towing, off‑road, desert heat/cold, plowing, lots of idle): Service around 5 years/100,000 miles, or sooner if tests show degraded protection or contamination

Tip: After the first change, many pros service extended‑life coolant every 5 years/100,000 miles as good practice, with annual test‑strip checks.

How to refill & bleed

Most F‑150s use a degas (pressurized expansion) bottle as the high point—there’s typically no manual bleed screw. Vacuum‑filling is preferred to avoid air pockets.

1. Drain

• Start with a stone‑cold engine. Open the radiator petcock (lower driver side) and the block drains if equipped. Capture old coolant for recycling

2. Close and vacuum‑fill (preferred)

• Close drains. Connect a cooling‑system vacuum fill tool at the degas bottle
• Pull 20–25 inHg vacuum, verify it holds, then draw in Motorcraft Yellow 50/50 mix until the system is full and the level stabilizes at the COLD FILL RANGE

3. Gravity fill (if no vacuum tool)

• Set HVAC to full HOT. Slowly fill the degas bottle with 50/50 until at COLD FILL. Massage upper radiator hose to burp air
• Start engine, idle with cap off until the thermostat opens and upper hose warms. Keep the level near the COLD FILL line; avoid overfilling
• Briefly hold 1,800–2,000 rpm for 2–3 minutes with heater on; check for steady cabin heat. Top up as needed and install cap

4. Warm‑up, cool‑down, recheck

• Road‑test, allow a full cool‑down, and recheck the level. Top to COLD FILL RANGE. Recheck again after a few drive cycles

PowerBoost hybrid notes

• The hybrid has separate coolant loops (engine and hybrid electronics/transmission). Vacuum‑fill both loops
• Use a scan tool service function to run the electric coolant pumps/bleed routine. If a scan tool isn’t available, place the truck in READY mode to run pumps/fans, cycle the heater from cold to hot several times, then cool down and recheck levels. Repeat until stable cabin heat and no gurgling are present

Additional tips

• Use only Motorcraft Yellow (WSS‑M97B57‑A1). Do not mix with Orange/Gold/Green coolants—cross‑mixing can shorten service life or form deposits
• Replace any aged/weak degas bottle cap (typically ~20 psi); a cap that won’t hold pressure can cause loss of coolant and overheating

Common cooling system issues on this generation

• Degas bottle caps that no longer hold pressure, leading to coolant odor or overflow—easy and cheap to replace
• Thermostat housing or water pump seepage (white crust at weep hole or housing seams) around higher mileage
• Heater hose quick‑connects or plastic T‑fittings that develop leaks; replace with quality fittings and new O‑rings
• Radiator plastic end‑tank seepage near the crimp after heat cycles, especially on vehicles with heavy towing use
• EcoBoost turbo coolant line seep/leaks at banjo fittings; look for pink/yellow residue and a sweet smell after shut‑down
• Active grille shutters stuck or debris blocking the condenser/radiator stack, reducing airflow and causing high temps when towing
• PowerBoost: auxiliary electric coolant pumps that get noisy or fail; improper bleeding after service can cause no‑heat or overheat complaints
• Mixed coolants or hard‑water top‑offs causing scale/gel—always use distilled water with concentrate and stick to the Motorcraft spec
