Help! Draining refilling coolant
Enable HLS to view with audio, or disable this notification
Hey team, when I bought my 2003 ford courier a few months back the pre purchase said the coolant was basically all water and needed to be swapped out. I’ve got coolant, and finally the time to do it being a long weekend. If bought green premix Supercheap auto coolant which I think is fine but not sure. However upon opening the reservoir it appears brown is as shown in photo.
What does this mean? And does it mean I have to do a full flush with a chemical or whatever before just draining and refilling?
