its not baba yung engine temp mo pag binago mo ang ratio......

try kung eh explain yung nabasa ko...... assuming may ratio kang 60(di water):40(coolant) then yung na achieve na temp. resistant mga 500C - claim by manufacturer (exag # lang) then ngayon binago mo ang ratio to 50:50 yung claim ng manufcaturer ai 600C (big #'s again for the sake of comparison). Somehow yung engine temp. mo ai 450C so 50:50 solution isn't pratical coz the 60:40 can still resist the temp.

The 50:50 solution is advisable if the engine temp somewhere higher than 500C. Talking of >500C tapos pag ginamit mo yung 60:40 chances are iinit yung engine mo cause its beyond control enviroment of 60:40 solution.

I'm open for correction kung mali ang pagka-intindi ko sa script ng coolant manufacturer
