[V8] It's that time of year...related to O2 Sensor Gas Mileage Thread :-)

[Ingo Rautenberg]

Huh?  Help YOU?  Lol.  Seriously, I will be happy to help when I can.  
Possibly this weekend, probably next weekend (depending whether I'll  
be doing business over the weekends).  About time you got that rack  
replaced, Zay!  And that labor is dirt cheap.  Why do I have a  
feeling that guy will be swearing up a storm?  Lol.

Your front coolant temp sensor is either flakey or the connection  
is.  When it gets a bad signal it causes the coolant gauge to go to  
full overtemp and the super duper cyclone fan is activated. The  
sensor is the one just to the right of the throttle body and plugs  
into the intake manifold (black sensor top).  The lead is  
ridiculously short and tight, which I surmise is part of the  
problem.  Coolant tank leaking from the seams indicates overpressure  
of the coolant system.  No fix for the tank except for replacing the  
tank.  But first find out why it's splitting.  Cylinder head gasket  
leak?  Clogged radiator?  bad thermoswitch at radiator?

Good luck my friend!
