i was looking around under the hood my my recently acquired 97 gtp. i popped open the radiator, and it has a orange color to the coolant. but what puzzled me was i opened the reservoir and its gray, and feels like grease on your finger....car doesnt over heat, or smell like its burning, temp gauge only gets to around 150ish. but still blows hot heat and what not. any ideas on what this could be? i checked the oil and its still clear and not milky. i just dont know where to start with this car. any ideas would be greatly appreciated
