When I do my coolant flush I still do it the old way:
1. Drain Coolant
2. Add 100% water to cooling system, start engine and let idle for 5-7 minutes with heater on full blast.
3. Repeat process 4-5 times.
4. When I add coolant at the end, I put in a 60% mixture to make a roughly 50% mixture.
It's more time consuming, but very easy. This was the method stated in old repair books, and a mechanic buddy of mine said they did it this way for many years.
Just wondering if I'm the only weirdo doing it this way.
