03/04 Cobra Coolant Flush.

[skratpiece]

I recently hit 50K. The coolant has never been flushed and I think it's time to flush it now. I'm not familiar with the coolant system, can someone tell me how to flush and fill. What is the best fluid to replace with? Thanks.

I found this link with a long write up. Should I follow this?
