Parts for your 2017 Ford Kuga-Coolant

2017 Ford Kuga coolant — what it does and how to look after it

Coolant is absolutely used and relevant on the 2017 Ford Kuga. Ford’s technical literature — including the 2017 Kuga Owner’s Manual and Ford Workshop Manual — specifies a liquid-cooled system that relies on a 50/50 ethylene‑glycol coolant/water mix. Motorcraft and Ford coolant datasheets further outline the correct organic acid technology (OAT) formulation and corrosion protection required for the Kuga’s alloy components.

In everyday terms, coolant carries heat away from the engine, raises the boiling point, prevents freezing, and protects the radiator, water pump, and internal passages from corrosion and scale. Without the right coolant, overheating, electrolysis and internal pitting can sneak up fast — not ideal on a daily driver or a weekend escape machine.

For 2017 models, Ford specifies an OAT long‑life coolant that meets Ford spec WSS‑M97B44‑D (commonly seen as Motorcraft Orange in many markets). Some later Ford Yellow OAT (meeting WSS‑M97B57‑A1) products may be approved as a service fill if the system is fully flushed first — the key is to match the Ford spec in the owner’s handbook and not to mix coolant colours or chemistries. A proper 50/50 premix with demineralised water gives protection down to around −37°C and maintains the inhibitor package at the right strength.

Service-wise, Ford schedules long‑life intervals — often up to 10 years or 240,000 kilometres under normal conditions, as noted in Ford owner information. That said, smart owners get the coolant strength and pH checked annually, especially if towing, driving in hot climates, or if the service history is patchy. If the age or mix is unknown, a complete flush and refill by the book is a solid move.

• Check the expansion tank level cold — keep it between MIN and MAX.
• Only top up with the correct Ford‑spec coolant, use demineralised water in an emergency, then restore the mix ASAP.
• Never open the cap hot, pressure and temps can be nasty.
• After a refill, bleed air and run the heater on hot to purge bubbles.
• Look for sweet smells, coloured residue, or damp hoses — early signs of leaks.

Professional servicing should include a pressure test, thermostat and fan checks, hose inspection, and proper recycling of old coolant — it’s toxic to pets and wildlife.

Popular questions about 2017 Ford Kuga coolant

What coolant type does a 2017 Ford Kuga use?
The Kuga takes a long‑life OAT ethylene‑glycol coolant that meets Ford spec WSS‑M97B44‑D (often Motorcraft Orange). Some workshops may use the newer Ford Yellow OAT (WSS‑M97B57‑A1) after a complete flush. Stick with a 50/50 mix and never blend different coolant chemistries.

How often should the coolant be changed?
Ford documentation allows for up to 10 years/240,000 km in normal service. Given Aussie and Kiwi conditions, it’s wise to test coolant strength yearly and replace earlier if towing, seeing high ambient temps, or if the history’s unclear.

Can different coolant colours be mixed?
Mixing is a no‑go. Different inhibitor packs can react, reducing corrosion protection and potentially forming gel-like deposits. If changing types or colours, fully flush the system and refill with one Ford‑approved coolant that meets the correct spec.
