[Chevelle-list] Is there really a "high flow water pump?"

[Brad Waller]

As Trooper originally stated, dropping the thermostat temperature will 
not affect overheating one iota. If you have a call that runs cool the 
160 will let it run as cool as 160.  But once it is open it is no 
different than a 180 or a 195 thermostat.  If the car is running hot, 
that all happens at 230+ degrees, long after all the thermostats have 
fully opened.

Other than a high modified car, any car with a working radiator and fan 
with a shroud should not overheat.  If you overheat, it is because the 
engine is not tuned properly or the cooling system is out of whack.
