    This is for anyone who owns and has knowledge re the cooling system of the E46 3 series coupes.

    I own a 2006 325Ci in Sydney and today, WITHOUT WARNING, I lost all my coolant. .Soon after that, I realized my engine was overheating and went in the red-zone.. I pulled over after a few hundred meteres and turned the car off and had it towed...What I'm worried about is ..have I damaged the engine gasket??? .. I opened the hood and saw no visible signs of damage and the engine head didn't seem to overheat..

    Any feedback of comments are welcome .. I'm seriously very worried about this..

    usually there is a weep hole on the bottom of the water pump when the bearing starts wearing out, it breaks a seal and anti freeze will drip from directly from the front of an engine. you do not mention year make or model or mileage of your vehicle, loosen the radiator cap just enough to keep pressure from building up, and keep the overflow topped off and check the radiator when it is cold to be sure there is enough coolant, this may buy you some time, but you need to get under the truck and find out where it is coming from. I would not go jumping to head gaskets and the other stuff mentioned, always look for the simple fix first, this could just be a loose clamp, so tighten up the clamps first, and start looking around under the truck to get an idea what the problem is

      Hey thanks for the reply ...its a car not a truck lol ...and secondly what had happened was that one of the radiator hoses cracked and in turn broke the bleeder screw, temperature sensor and expansion tanks...I have warranty so it was all covered and fixed .. all I had to pay for was the radiator hose..
