Hello all I plan to perform a coolant flush in a couple of days once I get my hands on some Toyota red. Currently when I check my reservoir it's pretty much empty but I don't run hot. When I look in the reservoir the little coolant that is there looks red. My question is can I go buy some coolant or distilled water for the time being just to get the level up in the reservoir until I perform the flush or should I leave well enough alone. My LC is a 00 and is new to me I have been driving it for only two weeks now. Thanks for the help.
