what is proper coolent to top off...which will mix with existing coolent ?????? Thanks

 

well when i left my over flow tube off (i forgot to put it back on )

i used

"peak global lifetime" the one in the gold colored jug...

or goto the dealership and buy your self a gallon...

 

Toyota Red Long Life Coolant (OEM).....DO NOT MIX OTHER COOLANTS UNLESS IT SAYS ITS COMPATABLE WITH TOYOTA RED OR TOYOTA APPROVED.....If its only to fill your overflow use it straight out of the bottle if its going directly into the radiator 50/50 coolant/water mix should be used

 

distilled water is a must when mixing the two together...
