If you didn't know already, I picked up a 300m on Wednesday. It had a coolant leak. A dealer replaced the tube under the intake that connects the reservoir and heater lines to the intake. Well, they went out of business and the guy who owned the car at the time was SOL when he found out it still leaked. I bought the car pretty cheap and tore into it right away. Well, here is the source of the leak. The NEW tube is missing a bracket to hold it on. It is a dealer only part, so, I will try to make my own bracket for it and have somebody at work weld it on.
