Thanks guys for all the feedback. Indeed here because of the high temperatures antifreezee is not an option. I will look into what type of coolant can be an option or even distilled water with some sort of lubricant. My car just get driven to the track ocassionaly, and that is like a 15 min drive. And raced on the track. So long street drives is not a concern.
It is a street and strip vehicle, however is pretty much used only on the track and barely on the street.
