E30 M3 coolant temp 3/4 way hot - solved !

[GAK-WEE_LOW@xxxxxxxxxxxxxxxxxxxxxxxxxxx]

     Hi
     
     Thanks for all the response on my '89 M3 running 3/4 way temp in 
     stop-and-go-traffic.
     
     In summary, the fan clutch was bad and the fuse to the aux fan was 
     blown. After changing the fan clutch and the fuse all is cool and 
     normal. The temp now doesn't go pass 1/2 way.
     
     By process of elimnation.
     
     Not water pump, because the temp was normal on highway and when car is 
     cruising along.
     
     Not thermostat, because the car doen't go to red after a start.
     
     I eliminated the possiblity of a blocked/choked radiator because it 
     was change 4 year ago.
     
     No leaks, because I did not loose coolant.
     
     Mail ordered a (expensive M3) fan clutch from Bavauto and replaced it 
     today and all seems fine. I was told that the 318i (much cheaper) fan 
     clutch may work on the E30 M3 but I didn't want to risk it.
     
     Thank all,
