AOA dear all,
As compared to water, coolant have higher boiling point and lower freezing point.
Coolant is usually used for following reasons:
1. Prevent Overheating
2. Avoid Rusting
3. And as an Electrical Insulator
I discussed the issue with my mechanic a few days ago. He said any coolant will do the work and the good combination is 75% coolant and 25% water.
I have been using 50/50 so far in my Khyber, now I will switch to said 75/25.
Best Regards and Safe Driving,
