Car broke down (HELP PLEASE)

A few days ago this happened:
Just purchased a 1992 325i about 7 days ago. The OBC kept displaying, check coolant level; so I did and it was at the line. I filled it up to the top of the rad to be safe. However, it kept displaying the same thing on the OBC. So I thought that perhaps the sensor was screwed. Today the car over heated! The top part of the rad that sticks out on the top were the hose fits onto, broke off. So I managed to put the hose on the rest of what was pertruding out of the rad, and it held without leeking. The car keeps overheating though. I can only drive a few blocks and it overheats. Does anyone know if it's the water pump or thermostat?
Thanks guys,

MY LUCK!!!!

Soooooo, I have replaced the water-pump (metal) with a new one, and a new rad as well as a thermostat. However it still overheating!!! Also, there still isn't any hot air coming out of the vents.
Any help would be greatfully appreciated.

After replacing the water pump, rad and thermostat... no hot air coming out of the vents can also be contributed to the heater coil. I had a similar problem on my Grand Am GT, where the A/C and heat wasn't working... turned out that the condenser leaked oil into the heater coil. After both were replaced, it was ok.

For the overheating... stumped there. Best bet is to have it checked out by someone.

oh oh!!!

looks like yer cooling system was not bled properly or theres an air trap. who installed all the new parts?

tip (if yer willing to ge Dirty!)- find the highest point of yer cooling system that is bleedable, sometimes theres a screw over the therostat and open it. turn on yer heater full blast and leave it that way. fill up the coolant resivour but not completely to the top.
fill up till coolant comes out from the highest point opened. close it and turn on the car and only idle it(don't rev it), squeeze some of the main hoses abit too push out air. monitor the temp and if it over heats again send it to a shop that knows beemers cause it could be internal!!

i'm sorry that i cannot explain it better cause i have to be there!
Good luck

Sounds like something is plugged perhaps in your rad.

one more thing if your car over heats again, don't dump cool water...or any water period on these motors.....that cracks the head.

just let it cool down on its own...so you can comfortabliy touch it (head) with your hand before restarting.
