Parts for your 2018 Ford Kuga-Coolant

2018 Ford Kuga – Coolant

Coolant is absolutely relevant and used on the 2018 Ford Kuga. The 2018 Kuga’s petrol and diesel engines are liquid‑cooled, and Ford’s Owner’s Manual and workshop literature specify an ethylene‑glycol, long‑life OAT coolant that meets Ford’s WSS‑M97B44‑D family of specifications (Motorcraft/ Ford SuperPlus type products are typical for this model year). Those technical sources make it clear: the Kuga relies on engine coolant for proper temperature control and corrosion protection.

What does the coolant actually do? It carries heat away from the engine to the radiator, helps prevent freezing in winter and boil‑over in summer, and guards the alloy block, head, turbocharger and heater core from corrosion and scale. It also provides lubrication for the water pump seals. In short, if the coolant’s healthy, the Kuga runs cooler, lasts longer, and the cabin heater works as it should.

For this model year, Ford specifies a long‑life OAT coolant. Owners should use a product that clearly states it meets the relevant Ford WSS‑M97B44‑D spec for the Kuga’s market. Stick with the correct colour/type, don’t mix different coolant chemistries. A 50/50 premix (or concentrate blended with demineralised water) is typically recommended. Only check or top up when the engine is cold—undoing the cap on a hot system can cause scalding.

As part of regular servicing in Australia and New Zealand, it’s smart to have the coolant inspected at each scheduled service (often every 12 months or around 15,000 km, model and usage dependent). The factory fill is a long‑life coolant, with a replacement interval commonly in the “very long” range for this spec—owners should follow the exact interval listed in the Kuga’s handbook, as it can vary by engine and market. Replace sooner if there’s contamination, overheating history, or cooling system repairs. When changing coolant, a proper drain, flush, refill with the correct spec, and bleeding of air via the degas bottle procedure helps avoid hot spots and heater issues.

• Check the cold level sits between MIN and MAX on the reservoir.
• Look for leaks, sweet smells, white crusting, or swollen hoses.
• Watch the temperature gauge and heater performance, unusual behaviour can hint at low or aged coolant.
• Never mix types, if mixed accidentally, arrange a full flush and refill with the correct Ford‑approved OAT coolant.

Popular questions about 2018 Ford Kuga coolant

Which coolant type and colour should a 2018 Ford Kuga use?
The 2018 Kuga uses a long‑life, OAT ethylene‑glycol coolant meeting Ford’s WSS‑M97B44‑D family of specifications. In many markets this corresponds to Motorcraft/Ford SuperPlus (often orange). Always follow the label on the expansion tank and the Owner’s Manual for the exact spec for the vehicle’s engine and build date.

How often should the coolant be changed?
Ford’s long‑life OAT coolant typically has an extended service life. Many vehicles of this era quote a lengthy time and distance interval for the factory fill, the precise figure for a 2018 Kuga depends on engine and market, so the handbook is the authority. If the coolant tests weak, looks rusty/murky, or the system’s been opened for repairs, replace it sooner.

Can different coolant colours be mixed?
Best not. Mixing different chemistries can reduce corrosion protection and shorten service life. If different types have been combined, the safest play is to drain, flush with demineralised water, and refill with the correct Ford‑approved OAT coolant to the right concentration.
