I just got a mk3 last month, new to the supra thing i bought it cause it was nice and seemed like a good deal. The guy i got it from had the guts of the termostat removed so it would run cooler. not a very smart guy, but I put a new water pump, termo, radiator, cap and hoses. When i rod on it or just drive it fro a while my coolant pushs out my overflow hose. Could any one tell me why this is. Ive tried alot but only thing i think it could be is a blown head gasket which was already done before so im not tryin to do that if it could be something else.
