I have a 2019 expedition with 48,000 miles on it I was told by the local Ford dealer that it is time to change out the coolant. He didn’t seem extremely savvy as far as if it should be exchanged or just an actual flush. I’m curious to see what the consensus is on that subject? Also as a sidenote what color is everyone’s coolant in the reservoir? Thanks
Ford recommends changing the engine coolant at six years or 100,000 miles on my 2015 Expedition.
The coolant reservoir and several coolant hoses failed at about 60,000 miles - so the dealer changed them and the engine coolant under Ford’s extended warranty. The water pump failed at 80,*** miles - so the dealer changed the engine coolant again when they changed the pump (under Ford’s extended warranty).
Dealers often “recommend” service - which is recommended to make them more money, not according to Ford’s service guidelines.
I did learn that Ford changed the coolant color (and maybe the formulation) on the coolant suggested for my vehicle - but I don’t remember what the new color is or the new Motorcraft part number.
Don’t always go by the color - go by what is recommended by the manufacturer.
