:)bhaiyon stop fighting with own experience & come back to original topic, last time during service at 3s dealer Toyota eastern motors, they cleaned my radiator & filled with ordinary water saying that coolant(toyota original) one was less so we flushed it & now its whole water, next time we will change with coolant, now time has come I need to change oil change & radiator soon, I have no plan to go to 3s now, so please tell me which one will be best in this hectic 50C temp. : putting whole 100% green coolant of nasa(almost 4-5 bottles will come @ Rs. 250 each almost 1250 max.) or put pink color Toyota coolant(with 50 50) with water ,cost is 1350 but I don't wanna add water, I want to put only coolant so which one will be best. nasa, pyra or any other brand available in Karachi. one more thing wat is difference between orange,pink,red & green coolant , is there any difference in specifications or just color difference according to brand
