does any one know what this is?

My DA55 motor has this yellow solid crude lifting the paint on the water pump (primary fluid circuit)
It may be related to a leak of the green coolant?
If the case is aluminum then it I don't know of a yellow aluminium based corrosion product
If is is a corrosion product I would like to known.
Regards

Perhaps it is a yellow chromate priming paint. Do you have a photo of the area that you can share so that we can see exactly what it is that concerns you?
