I live in a hot country, do I need to use coolant in my radiator.
There are 2 schools of thought,
1. I have been told that if you add coolant to your system when it has been run with distilled water, chemicals in the coolant will harm your system? reason given over the years there has been slight corrosion and some of the chemicals in the coolant will make it worse
2, If you change to a coolant, the chemicals in the coolant will halt the corrosion. Any comments? please
