So my old Capri recomends a 50/50 Ethylene Glycol antifreeze-Water mix as per the owner's manual.
The other day returning from a loong 1600 Km road trip i noticed my temp gauge was climbing more than usual, almost to the max, so i pulled over and carefully opened the rad cap, more than a bit of coolant escaped from the radiator, i continued to the nearest gas station and put in some cheap distilled water in it, after that it no longer overheated and it seems to be fine, i was doing 80-100 Mph for about 100 Km ( 60 Miles ), outside temps was around 35C ( 95F ).
I am currently using green ethylene glycol coolant, pre mixed 75% water and 25% ethylene glycol, it was changed last year.
Should i go up to a 50% coolant or go lower than 25%? Where i live we never see temps below 0C ( 32F ), the hottest summer days it might be 40C ( 104 F ).
