I have the same problem I think, gears were jumping then sudden overheating sign then steam .. when checked water tank was steaming out cream like liquid…

car still starts fine.

no creamy stuff in when checked the engine oil filler cap.

so, can it be just oil cooler with maybe faulty pump or oil cooler or both?

is the engine ok? Gearbox?

What’s the fix?

If you've got creamy coolant, stop driving immediately and take it to a specialist lest you destroy the engine which will likely cost more to repair than buying a new car.
