hey cl, i need a lil help. driving to work today I realize my car is over heating. so i was in a hurry i went to auto zone and buy coolant but i buy %100 coolant not the 50/50. so i was wonder if can use that or do i have to use 50/50? i got a gte with aluminum radiator and a intercooler as well. btw my car is sc300. thank you for your help and answer.

 

no. i would mix it first. u dnt want to mess ur engine up for something as simple as mixing the coolant. also use sterile wated. i know it sounds stupid but it will prevent rust in a huge way.

toyota uses a red coolant iirc. but i use the autozone one too and its fine.

 

you can use it its not going to hurt anything just mix it up l ater when u get home.

 

Straight antifreeze does not absorb heat well.
Your engine may run a bit warmer than usual.

... and its distilled water, not quite sterile

 

get some water, preferably distilled, as it does not have minerals in it that will rust your cooling system components. then get a gallon jug and mix half and half. you get 2 gallons of 50/50 so u have some extra
