I'm assuming $80 in coolant marked up to $120 and an hour of labor at $220. So my guess is dealer costs are about $340. Am I close or did they assume 1.5 hours or more?

DIY, add in $20 in distilled water for some fill and drain cycles to 'flush' the system. Total $100.

It was about $300. I was at just over 60k miles and had a bunch of fluids swapped out all at once. The coolant flush seemed excessive but I was too lazy to shop around this time.

Ford long life coolant shouldn't need attention to 100-150K at least.

Make sure the dealer doesn't use the flush machines recycled coolant.
