Coolant Tips- 50/50 is the most commonly recommended ratio.
- Never exceed 70% coolant — it actually reduces cooling efficiency.
- Never use pure water — it corrodes and has a higher freeze point.
- Don't mix different coolant types/colors.
- Flush the system every 30,000 miles or per manufacturer spec.
- Use distilled water, not tap water, to prevent mineral deposits.
