I did coolant replacement on my 2017 Fiesta ST, and one thing I’d like to add is it helped immensely to remove the radiator bleed screw prior to refilling the degas bottle with fresh coolant. The bleeding procedure was a lot faster after doing this. Pretty much, I attached a small hose to the nipple where the bleeder screw is secured, and as soon as I saw steady coolant flow, I knew all the air escaped from the radiator.
I've owned cars since 1977 and have changed coolants many times, but the coolant change for my low-mileage 2016 Ford Fiesta is proving a problem. For a start, the Haynes manual states (extraordinarily): "As a guide, only two-thirds of the system's total capacity (5.8 litres or 10 pints) is likely to be needed for coolant renewal". But when I came to do the draining, only about 2 litres emerged, not even 4 litres. As advised, I then filled/ topped up with water and ran the car before draining again, only to produce a mere 2 litres yet again. I am at something of a loss at present. Also, worthy of note is the extraordinarily long process of running the engine to ensure no air locks. I shudder to think how much a service garage must charge for such a laborious task!
Do I need to flush the system too? Or just drain like you did in the video? If the system has not been contaminated that is, just regular preventive maintenance.
Hey there, I'm just looking to top up the coolant but my cap is stuck, I think it's cross threaded as it just keeps turning but doesn't come off. Any ideas how to remove it without damaging it and then putting it back on after I've topped it up?

Thanks for the info. On the vehicle in the workshop, there was no bleed screw, but I should point out that the manual excludes the ST models.
Lovely car. I wouldn't mind one myself.
Amazing I needed to see this
You're welcome!

There's no need to flush the system unless you have an overheating fault and suspect a blockage.
Great tutorial
Glad you think so!

As a last resort, try cutting the old cap off with a Dremel. It will cost you a new cap, but will save destroying the threads on the tank.
@@HaynesManuals yes was contemplating something like that. I pick up a new cap tomorrow and will have a look.
Why my ford fiesta 2013 suddenly drinking coolant? need to refill its resovoir every 500 kms no sign of leakage i live in uae
