there is a smell of coolant coming through the air vents any time i use my heater on my 306 diesel.

sometimes it even comes out in the form of steam.

car engine temp ok and coolant levels are not going down by much.

also there is a relay attached to the front of the car near the radiator fan. its not the green one inside a triangular box but its close to that. its cylindrical in shape. im just wondering what it does???

thanks for the help
