E-34 (535i) Radiator Question

[BnglowBill@xxxxxxx]

I recently had my oil changed and thought it was leaking afterwards.  After 
having the leak checked I realized it was actually coolant from the plug on 
the driver's side bottom of the radiator.  I tried to tighten the plug just a 
bit so I didn't strip it, but it seems that it was already stripped.  When I 
removed the plug, very little coolant came out.  I'm not reeeeal familiar 
with the radiator on an E34, but shouldn't I have seen the radiator drain 
when the plug came out???  Is this a common problem with these radiators?  
Any help is appreciated!

Thanks
