Coolant flush on 2016 F-150 5.0
Greetings,
Question.I have, or am about to have completed a coolant system flush IAW Haynes manual instructions (using distilled water). I drained and flushed about 7 1/2 gallons of distilled water through the system, drain/fill/flush, until I was draining clear clean water from the radiator. Problem. I was only able to get a little over 1 gallon of new coolant (yellow/Motorcraft) into the system. Been trying to burp out the air bubbles, and still it won't take the rest. Is it possible that there's still a lot of water in the system? I hate to open the drain and lose new coolant. Any help is appreciated already. smile

Oui, c’est très probable qu’il reste encore pas mal d’eau dans le circuit. Sur beaucoup de moteurs, surtout modernes, tu ne peux pas vidanger 100% du liquide uniquement par la purge du radiateur. Il reste toujours du volume dans le bloc moteur, le chauffage (heater core) et certaines durites.Du coup, si tu as déjà fait plusieurs rinçages à l’eau distillée, ce que tu récupères maintenant est un mélange eau/coolant, et c’est normal que le système “refuse” de prendre la quantité totale de liquide neuf.
