Ford C-Max Engine Coolant & Inverter Coolant Change

I'm looking at different coolants that are capable of replacing the inverter and engine coolant on a Ford C-Max Energi Hybrid.

I believe this Peak Yellow coolant is a direct replacement.

However there are no certifications and since Ford issued a TSB for this model so I'm trying to find a precise replacement.

Has anyone gone down this road?

Is that the same as Ford Yellow aka Prestone Cor-Guard?

If so, just get the Prestone. It's much cheaper

I am looking at getting the Preston Platinum. I think I'm going to call and find out about their certifications for this coolant

I’d use the Prestone Platinum myself. Ford did say their new yellow coolant - also Prestone is OK for ones filled with Dex-Cool originally. Use the premix for the inverter, you want DI water ideally.

Thanks very much for that. I also ordered the Peak Yellow but I think the Platinum will be fine in the end. We needed more brake fluid this afternoon and the Prestone was among an amazing number of well-stocked brands at the Walmart.

I thought about the universals too. But I think spending $10 extra on an assured fit is the best choice in this situation.
