EB Coolant Flush

[Chops]

Is there a trick to doing a proper coolant flush on our EB’s?

I ask because my Lobo was built with the standard radiator & fan instead of the correct 4K radiator & fan.

Ford issued Customer Satisfaction Recall 25B34 to swap them out.

My local Ford Dealer is now doing the swap and coolant replacement. I’m confident it will be done correctly. However, I will inevitably check for leaks on my garage floor after it’s back.

But I also heard the EB needs to be “burped” correctly to avoid bubbles in the system and subsequent overheating? I will go down this rabbit hole myself - but just wondering if any forum members have personal experience on this procedure? Thanks!

Thank you - that link had what I was looking for:

• The EcoBoost "Burp" Hazard:Modern EcoBoost blocks are notorious for trapping stubborn air pockets in the cylinder head during a refill. If you don't bleed it perfectly, it will hot-spot and overheat. Using a vacuum-lift coolant refiller tool makes this effortless. If doing it manually, you will have to cycle the heater and "burp" the reservoir multiple times.
