The winter beater e30 has developed a bad coolant leak. I'm trying to get an idea of what the problem is, but I find I really don't know much about these cars. The leak is close to the firewall but down low. It's not the heater core hoses that are leaking.
I took a look at the diagram, and I'm suspecting it has something to do with the throttle housing assembly. Why the hell does it have water hoses connecting to it again? Where does hose #15 go? Also, could the leaking hose be #14? I can't get under my car to look.
