We have a coolant leak which appears to be comming from the back of the engine. From looking underneath it is comming straight down and hitting the headers. However we can not find any leaking hoses. It was overheating so I turned on the heat to get some of it out of the car but no heat was comming from the vents. Just cold air. Any idea what this could be or where I should check for the leak? I have been reading and can only think of the heater coil? When the car is running antifreeze is pouring out from underneath and white smoke/steam is comming from the engine compartment.
