Hi. Sorry if this has been asked before. Tried a search but can’t find the answer. Is the Ford Super Premium Plus antifreeze WSS-M97B44-D pre-mixed or concentrate? Will be doing a 10yr coolant change soon and want to know if I need 6 litres of the above, or 3 litres plus water. Thanks. 

Concentrate

Thanks. Much appreciated. 

When the cooling system of the 1.0 ECOboost is completely drained (including engine block and heater matrix) 6 Litres of coolant in total will not be enough. When the coolant is drained from the radiator valve only 50% of the coolant will be drained. The rest of the coolant will stay in the system.

Also be aware that the cooling system needs to be vacuum filled. Without vacuum filling large amounts of air can be trapped inside the cooling system. Without the possibility to manually bleed the system (bleed valves) these amounts of air can easily result in engine damage.

Thanks for the info. Any tips for a proper drain and re-fill? Most of the guides I’ve seen are a simple drain, flush, re-fill and bleed while running the engine perhaps with some hose squeezing.

Without the appropriate equipment to force the coolant into the system under vacuum, you can't renew the coolant.  The "traditional" methods are irrelevant in terms of the 1.0 EB engine.

Great. Down to the local Ford stealer it is then. Thanks for the info. 

Is there much point doing a ‘mini re-new’ i.e drain the reservoir and radiator and re-fill with the couple of litres of new coolant? Will this still give issues? Just thinking that at least keeps some new coolant going in?

Jeez, I wish I had found this prior to refilling mine....

This sounds really weird. What is different (mechanically) about EB from other engines?

EBs are still around, aren't they?

Most modern Fords are meant to be vacuum filled.  Though the 1.0 EB should bleed through the degas hose without vac filling.  Just take care to make sure all the air is out before pushing the engine hard.

Direct injected, turbocharged EcoBoost engines run considerably hotter than conventional indirect injected, naturally aspirated engines and are therefore a lot less forgiving when running hot. Even the slightest overheating can (and usually will) result in serious damage.

The 1.0 EcoBoost is notorious for air pockets remaining trapped inside the engine block when not being vacuum filled properly.

These air pockets are extremely hard to remove without vacuum filling. Since air pockets are the main reason for localized overheating of the engine block it is extremely important to fill the coolant properly without introducing any air into the system


As said most Ford models that were introduced within the last 15 Years are prescribed to be vacuum filled.

Also worth pointing out that these engines don't have a cylinder head temperature sensor and if the coolant temperature sensor sits in an air pocket the overheating will not be detected in time to save the engine.

That happens when you try to type, watch the TV and have dinner at the same time.

Instead of typing "overheating" it should have been "serious damage" (now corrected.


Note that only the Focus MK3 does not have a cylinder head temperature sensor. The Focus MK3.5 has a cylinder head temperature sensor on the 1.0 EcoBoost.
