I found out that my cooling fans are not working properly.
One fan starts at about 230 to 240 degrees which is not good as we all
know. Both fans spin freely any ideas on where the sensor or module might be that these fans are controlled by.

Why isn't it good? Assuming you have an LT1 the factory settings are main fan on at 228 and the aux fan on at 237. If both fans are doing that you are good. If main fan is not coming on then next question is does it come on with the a/c? It should.

observe a what temp the fans come on and post the #'s

That sound correct. I still would lower the temps a bit, as they run that hot for emmisions. I like my main fan to come on at 205* off at 190, secondary try 7 or so degrees hotter... My oppinion...
