Coolant color/compatibility

[nate20gt]

I have a 2020 GT, my coolant was low and the local auto parts store said to use Motorcraft Gold to top it off since they were out of the orange and it's going away. I did but now I'm reading that it should have been the yellow not gold? Do I have to flush it now? Too many colors! Thanks.

I'm sure there's someone smarter who can tell you for sure, but afaik Ford recommends the Yellow not the gold.

Yellow can mix with the orange, but I don’t think gold can.

The coolant info is now stickied here at the top of this sub-forum:

Yeah, gold is a hybrid organic acid style coolant, it will definitely cause sludging issues over time. You need OAT or P-OAT to top these cars off.

Thanks for the replies. I had the dealer flush and fill it.
