---  I don't agree.  My coolant gauge isn't working properly,  and my rad fan 
circuit works fine always.  And I run the rad switch  disconnected per Keiths 
diag page, my 4th v8 running this way (and no  hooking up the other sensor 
doesn't change the issue).   I'm pretty convinced that the circuit trace in the 
instrument cluster isn't  giving the proper resistance on a lot of 
'misdiagnosed' overheat v8's.   Keith gives a good diagnostic run down of fan operation, 
but the *very* first  test is to confirm what you think is happening (overheat 
indicated on the  guage), really is.
 
In the KISS strategy, it's the right thing to do first.
