So I've got a '91 318is that's been having issues overheating lately. I flushed the radiator, but noticed the distilled water wasn't circulating when I first started so I decided the water pump must be bad. I've now replaced the water pump and thermostat and the car still overheats and still doesn't seem to be circulating coolant. Anyone know what the issue could be? It's also got an electric fan that's working right so I know that's not the issue

If bleeding it is a different process than that I haven't bled it, but would like to know how.sigpic

Having air in the system could definitely contribute to overheating issues. Also might want to consider replacing the thermostat, simple process that ended up solving my overheating issues.

Air, or tstat is stuck. IDK the condition of your car, but a bad head gasket can cause overheating problems.
You should just go ahead and replace the t stat. After that, open the bleeder, with the engine on, then fill it up until its full. Then, it may take a minute for the thermostat to open, when it does, it may take some more coolant.
Also, a tip for bleeding, jack the front of the car up and turn the heater on while you're bleeding.Last edited by MrBurgundy; 11-16-2017, 03:14 PM.

Do you have the issue at speed or only when still? Perhaps the issue is a bad fan clutch?sigpic
