ok, I just bought my first supra and it has a few problems. The one that I'm worried about is my car keeps loosing coolent while driving. I have to put about a half galon in it every time I go to drive it. I have all new hoses and thermastat my oil color is fine I just don't know where it could be going any help would be cool. I know this is probably a dumb question but bare with me I don't know much about toyotas'.:1zhelp:
