I recently flushed out my entire system in my 2000 to Zerex G-05 coolant 50/50 with distiled water. I was unaware at the time that the G-05 already contained the needed SCA additives so I added 2 bottles of the stuff from the ford dealership to the mix. Is this gona be a problem if so please advise so I can fix the situation ASAP. Thanks

 

Okay, well I did a search and tward the end of 18 pages of threads I found a few threads that state your not supposed to add additive to the gold Zertex G-05 coolant and that your also not supposed to use the gold stuff in motors earlyer than 2002. So Im gona flush out the system again tomorow and replace with the green stuff and additive. So after reading many posts about coolant and what to do, I have learned that you need to go back and read even more to get the whole story and all the facts not just a few recent posts. I just hope that I havent harmed my motor.
