cold E-30

[JHahn22@xxxxxxx]

Hello Folks,
My 89 325i seems to be running very chilly.  I just got the A/C working 
again, (with R-134 conversion), and the engine coolant temp guage is barely 
out of the Blue section.  It was running at a little under a 1/4 of the 
guage, but now it seems to be dropping some.  The outside temp did drop about 
20 degrees in the past couple days, but. . .
How reliable are the temp guages on these cars?  Would a T-stat being stuck 
open cause this perhaps?  
Also, how quickly would a fan missing two blades start damaging other 
components because of lack of balance?  THe missing blades are separated by 
one intact blade, if that says how off balanced it is.  The fan originally 
was an 11 blade fan I believe.  I have the replacement, just haven't had time 
to put it on yet.
Thanks,
Jake
