• Sweet odor inside the cabin: This can point to a leaking heater core, which is inside the dashboard and can be a more involved repair.
• Stains or residue on engine components: Dried coolant leaves a characteristic crusty, colored residue on hoses, fittings, or engine block surfaces.

How to verify and confirm the issue

Confirming a coolant leak on your 2019 Ford Escape involves a systematic approach, starting with visual inspections and potentially moving to more advanced diagnostic methods. Always ensure the engine is cool before working with the cooling system to avoid burns from hot coolant or steam.

• Visual inspection (cold engine):
  • Check under the vehicle: Look for puddles or drips, noting their color and location.
  • Inspect the coolant reservoir: Check the fluid level against the "MIN" and "MAX" lines. Look for cracks or damage to the reservoir itself.
  • Examine hoses: Follow all radiator hoses, heater hoses, and smaller bypass hoses. Look for cracks, bulges, soft spots, or signs of dried coolant residue around clamps and connections.
  • Radiator inspection: Look for visible damage, bent fins, or wet spots on the radiator core.
  • Water pump area: Inspect the area around the water pump pulley and housing for leaks or residue. The water pump is a common failure point for many vehicles, including the Ford Escape, as discussed in our Ford vehicle hub.
  • Thermostat housing: Check for leaks around the housing where it connects to the engine block or hoses.
  • Heater core lines: Follow the two hoses that go into the firewall towards the cabin. Leaks here can cause a sweet smell inside.
• Pressure test: A cooling system pressure tester can be rented or purchased. With the engine cold, attach the tester to the radiator or reservoir fill neck and pump it to the specified pressure (usually indicated on the cap or in the owner's manual). Leaks will often become visible under pressure, even small ones. Maintain pressure for 15-20 minutes.
• UV dye test: If a leak is elusive, add UV dye to the coolant system. Drive the vehicle for a day or two, then use a UV light and special glasses to scan the engine bay and undercarriage for glowing leaks.
• Check for TSBs (Technical Service Bulletins): While not specific to a single OBD-II code (you can learn more about Browse OBD-II codes here), sometimes manufacturers issue TSBs for known coolant leak issues on specific models and years. A Ford dealership or a reputable independent shop can check for these.

Common causes (most likely first)

Several components in the 2019 Ford Escape's cooling system can fail, leading to leaks. Understanding the most common culprits can help narrow down your diagnosis.

• Degraded or loose hoses: Over time, rubber hoses can harden, crack, or become brittle. Clamps can also loosen, especially after temperature fluctuations.
• Radiator damage: The radiator can suffer from corrosion, impact damage (from road debris), or fatigue cracks, leading to leaks in the core or end tanks.
• Water pump failure: The seals or bearings in the water pump can wear out, causing coolant to leak from the weep hole or around the pump housing. This is a common wear item.
• Thermostat housing leaks: The plastic thermostat housing, or its gasket, can crack or degrade, leading to leaks where it attaches to the engine or hoses.
• Coolant reservoir tank: The plastic reservoir can develop cracks, often due to age, heat cycling, or manufacturing defects.
• Heater core: While less common, the heater core inside the dashboard can leak, resulting in a sweet smell inside the cabin, fogging windows, and wet floorboards.
• Engine block or cylinder head issues: In rare and more severe cases, a cracked engine block, cylinder head, or a blown head gasket can cause external or internal coolant leaks. These are typically accompanied by other severe symptoms like white smoke from the exhaust, oil/coolant mixing, or misfires.
