I guess I was just reading about the new gold coolant by Motor craft and was wondering if it was better than the orange that came stock?The 6.7L PSD has shown no cooling system concerns related to the coolant itself that I am aware of. Problems that I HAVE seen are related to lack of maintenance and the MIXING OF COOLANT TYPES. I am with HEAVYASAULT in that there really isn't anything necessarily "better" than the Motorcraft Orange coolant that will make any discernible difference.
So has anyone made the switch to the new Yellow coolant? I have both my systems completely flushed out and want to know is the Yellow coolant compatible with my 2012 components? Thanks for your help!Orange stuff requires maintenance and the new yellow/green stuff is maintenance free. That would be the reason I could think of. The test strips needing to be in date, adding additive or replacing it if the test strips indicate. If Ford thinks a different formula poured into the same engine becomes hands off for 5 years then I would think that is less risk that it is maintained wrong and the oil cooler stops up or whatever might ever be known to us in the future to happen.
