Was driving my 2015 st from school and the engine light came on and my temp gauge went all the way up and my engine seemed to be cutting out. Stopped and turned my car off. Waited about 5 minutes and started it again and the temp gauge was at operating temps. Wasn't cutting out. So I drove it home like 3 blocks going really slow like 10. Came home opened the hood and there is a light tan clearish oil all over my radiator, throttle body/intake manifold. Engine oil is at a good level and not dirty. Transmission shifted fine. But the coolant/antifreeze reservoir is empty. And I didn't think antifreeze is oily and almost clear. What could be up? Don't see how I could have cracked my block from overheating or anything because the temp gauge went down so fast. And since I still had a normal level of engine oil. Power steering seemed fine and I don't get how that could cause the engine to overheat and act weird. Last night I changed my shift bracket bushings. Idk if I accidentally dropped something into the engine by a moving part causing something to get punctured. Any ideas? Most likely will end up towing to a local shop if I can't figure it out.
