Guardian 75D coolant

Does anyone know if it is ok to use zerex G-05 coolant in a Guardian 75D if I flush the cooling system?

Guardian 75D coolant

Hi, . I just did a simple search within this very forum section, and came up with this thread item from a few years ago. It may help you.
The search function within iRV2 is often quite helpful. Try it sometime.
Offer all thanks to member Honeymoo 2.
