adding coolant

[moosey42]

Is it ok to add zerex g-05 to the ford gold coolant? The bottle says to do a 50/50 mix. Is this the best mix ratio to use?
Thanks

Yes, Zerex G05 is correct if you have the Original coolant in your system. I would recommend a 50/50 ratio unless you are in extreme temps. Most other guys that I talk to also run 50/50
