Parts for your 2022 Ford Escape-Radiator cap

2022 Ford Escape radiator-cap: what’s actually fitted and why it’s different

For the 2022 Ford Escape, a traditional radiator cap on the top of the radiator isn’t used. Instead, the cooling system is built around a sealed radiator and a remote, pressurised coolant reservoir (often called a degas bottle) that has its own pressure cap. So if someone’s hunting for a “radiator-cap” on a 2022 Escape, it’s not relevant to this model — the only cap they’ll interact with is on the coolant reservoir under the bonnet.

This setup is confirmed in Ford’s technical literature. The Ford Workshop Manual for Escape/Kuga (Section 303-03A, Cooling System) specifies a pressurised degas bottle as the fill and pressure-control point, with the radiator itself remaining sealed. The 2022 Ford Escape Owner’s Manual points owners to the coolant reservoir cap for any topping-up and includes the usual “do not remove when hot” cautions. Ford’s parts catalogues also list a “coolant reservoir cap” for this model rather than a radiator top-tank cap.

Why the change? Modern engine bays are tightly packaged, radiators use lightweight plastic/aluminium construction, and a remote, high-mounted reservoir makes bleeding air and maintaining the correct pressure far easier. The cap on the reservoir handles pressure relief and vacuum return, keeps the system sealed, and helps reduce hot spots by letting air separate out. It’s a tidy solution that improves reliability and serviceability.

For owners and techs, the practical takeaway is simple: treat the coolant reservoir cap as the pressure cap. Only remove it when the engine is completely cold. If there are signs of coolant loss, staining around the cap, perished seals, or if the system isn’t holding pressure, the reservoir cap is a prime suspect and is inexpensive to replace. Always refit the cap firmly so it seals, and stick with a quality, correct-pressure replacement that suits the Escape’s engine and cooling system spec. Use only the coolant type listed in the vehicle’s owner’s manual, and never mix types.

Popular questions

Does the 2022 Ford Escape have a radiator cap?
It doesn’t have a cap on the radiator itself. The system uses a sealed radiator and a pressurised coolant reservoir (degas bottle) with its own cap. That reservoir cap is where pressure control and filling happen.

Where do you add coolant on a 2022 Escape?
Coolant is added at the coolant reservoir only, and only when the engine is cold. The translucent bottle is marked with MIN and MAX. Don’t remove the cap while hot.

When should the coolant reservoir cap be replaced?
If the seals are cracked, there’s dried coolant around the threads, it struggles to hold pressure, or after years of heat cycles, it’s wise to replace it. Use a quality cap that matches the factory pressure rating and follow the owner’s manual for coolant type.
