Coolant System Leak - HELP
I have a '91 318i.
This summer my engine kept getting hot. I replaced the fan clutch, then the thermostat. But still, there was a small leak in the radiator/coolant system -- because I had to keep adding coolant. This small leak turned into a huge leak yesterday, after the fitting on this one part broke. I need help figuring what this part that broke is called. (the piece i'm holding in my hand is the fitting that broke -- thus a big leak)
I had to take off the airbox to get to this piece, and the drawing I made can give you more of an idea of what this specific piece is.
I need the help of you bimmer techs/geniuses in finding out:
1. what this piece is called,
2. how/where to order a new one (if you know a good supplier)
3. any tips on installing a new one
