[DML] Re: Fan trouble

["Harold McElraft" <hmcelraft@xxxxxxx>]

Jumper or connect the two wires at the otterstat. Do the fans come 
on? If they do - then the otterstat is not activating the fans for 
one of several reasons including a bad otterstat. You should check 
the temperature of the coolant pipe at the otterstat with a temp gun 
to monitor heat of coolant at otterstat. If they do not come on when 
jumpered then you have a wiring problem you need to trace down.

otterstat or if I turn on the AC. I have tried two different (new) 
otterstats from two different vendors. The otterstat is pointed 
downwards and I have manually bled the system at the water pump and 
the upper right  radiator location. The pipe in which the otterstat 
is located is angled upwards towards the rear, so presumably any air 
should rise above the otterstat. I have also installed a Fanzilla, 
new thermostat, self bleeding kit, a new temperature guage and 
sender and the fluid in the fill tank is well above the hose 
connection point. I have not found any leaks in the system. When 
driving, the temperature guage will rise well above the point at 
which the fans should turn on, if I turn on the AC, the fans kick in 
and the temperature drops. My next plan is to drain the system 
completely and refill it. What else may I have missed ?
