2023 Ford Escape — Coolant Capacity & Type

The 2023 Ford Escape holds roughly 6.5–9.0 quarts (6.2–8.5 liters) of engine coolant depending on engine and options; hybrid models add a separate power‑electronics loop with about 3.0–4.5 quarts (2.8–4.3 liters).

Quick answer

• Total cooling system capacity (engine loop): about 6.5–9.0 qt (6.2–8.5 L), depending on 1.5L, 2.0L, or 2.5L HEV/PHEV configuration. Hybrids add a separate electronics loop of ~3.0–4.5 qt (2.8–4.3 L).
• OEM coolant spec: Motorcraft Yellow Antifreeze/Coolant (yellow color), P‑OAT/Si‑OAT chemistry, meeting Ford spec WSS‑M97B57‑A1.
• Mix ratio: Use 50/50 premix, or mix concentrate 50/50 with distilled water (up to 60/40 for extreme cold; do not exceed 60% antifreeze).

Capacity by engine option

• 1.5L EcoBoost (3‑cyl): approximately 6.5–7.5 qt (6.2–7.1 L) engine cooling system
• 2.0L EcoBoost (I‑4): approximately 7.5–9.0 qt (7.1–8.5 L) engine cooling system
• 2.5L Atkinson HEV (hybrid):
  • Engine loop: ~6.5–7.5 qt (6.2–7.1 L)
  • Power‑electronics/battery loop: ~3.0–4.5 qt (2.8–4.3 L)
• 2.5L Atkinson PHEV (plug‑in hybrid):
  • Engine loop: ~6.5–7.5 qt (6.2–7.1 L)
  • Power‑electronics/battery loop: ~3.0–4.5 qt (2.8–4.3 L)

Notes: Capacities vary with options (AWD, tow package, heat exchangers). If exact fill volume matters, measure what you drain and top up to the “MAX” mark on the degas bottle, then verify freeze protection with a refractometer.

Flush interval

• Normal service: Motorcraft Yellow is a long‑life coolant; replace at up to 10 years/200,000 km (about 120,000 miles) or as indicated by the maintenance schedule. Replace sooner if contamination or component replacement occurs.
• Severe service (frequent towing, extreme temps, dusty/corrosive environments): consider 5 years/60,000–75,000 miles, with annual freeze/boil protection checks.

How to refill & bleed

1. Safety first: Work only on a cold engine. Use approved coolant meeting WSS‑M97B57‑A1. Capture and recycle old coolant.
2. Drain: Many Escapes do not have a radiator petcock—disconnect the lower radiator hose at the radiator to drain the engine loop. For hybrids, the power‑electronics loop drains at its lower hose; keep loops separate.
3. Close and prep: Reconnect hoses and clamps. Set cabin heat to full hot. Raise the front of the vehicle slightly to help purge air.
4. Vacuum‑fill recommended: Using a cooling‑system vacuum filler greatly reduces trapped air, especially on turbo and hybrid models. If you don’t have one, proceed with a slow gravity fill.
5. Fill engine loop: Slowly fill the degas bottle with 50/50 until the level stabilizes at the “MAX” line. Some 1.5L/2.0L setups include a small bleed screw near the thermostat housing or upper hose—open briefly until coolant runs bubble‑free, then close.
6. Fill hybrid electronics loop (HEV/PHEV): Use only the specified coolant. Vacuum‑fill is strongly recommended. If available, use a scan tool service function to run the electric coolant pump and open the coolant control valve to assist purging.
7. Warm‑up/bleed: Start the engine and let it idle with the heater on. For non‑hybrids, hold 1,800–2,000 rpm in short intervals to move air. Watch temp gauge and hose temps. Top off to “MAX” as the level drops.
8. Cool down and recheck: After full cool‑down, recheck both reservoirs (engine and, if hybrid, electronics). Verify level is at “MAX” and test freeze protection (target ~‑34°F/‑37°C with 50/50).
9. Final checks: Inspect for leaks, verify radiator fan operation, and confirm cabin heat. Recheck levels after the first full drive cycle.

Common cooling system issues on this generation Escape (2020–2023)

• Degas bottle cap or seam seepage: Weak caps can vent early; replace the cap if you smell coolant with no visible leak.
• Quick‑connect hose O‑rings: Minor seepage at radiator or heater hose connectors—look for pink/white crust and address early.
• Water pump weep (1.5L/2.0L EcoBoost): Belt‑driven pumps may seep at the weep hole as mileage climbs; watch for coolant odor and slow level loss.
• Thermostat housing and plastic tees: Aging plastics can crack or warp; inspect any plastic junctions during service.
• Air pockets after service: Inadequate bleeding can cause intermittent no‑heat or hot‑running at speed. Vacuum‑fill or use bleed screws where equipped.
• Hybrid coolant control valve or electric pump faults (HEV/PHEV): Can set DTCs (e.g., P26xx range) and cause reduced power or overheat warnings. Proper bleeding and component testing are key.
• Active grille shutters or cooling fans: Stuck shutters or a failing fan control module can raise temps under load.

Use only Motorcraft Yellow (WSS‑M97B57‑A1) or an equivalent that explicitly lists that Ford spec; mixing coolants can shorten service life and reduce corrosion protection.
