My usual dysfunctional Ford dealership wants $160 to change the engine coolant, and says they don't recommend routinely changing the M/E coolant. Owner's manual says to change both.

Has anyone changed both systems and is it a DIY type of service? Would I need to flush the systems or just replace coolant? And what do you think about only changing the engine coolant?

Thanks

I have a 2005 FEH
