        Valid Point > To a Point ~ Let's consider this ~ If WW is able to create a Condition that Improves Heat Transfer From Eng' Metal to Coolant & Coolant to

Radiator Metal & Coolant to Thermostat then the Thermostat Could Conceivably Sense Heat Changes More Quickly & Therefore Respond More Quickly to those

Temp' Changes ~

        But ~ Also To Be Considered > Since Our Temp'Gauges & Temp'Sensors Only Supply Us with the Temp' of the Coolant, We can Only Assume that We

know the Actual Temp' of the Eng' ~ Since We Don't have PistonTop or Cylinder or Head Temp' Sensors, We just have to have Faith that the Coolant is able

to give Us & The ECU accurate info with which We & The ECU can develop an Educated Guess as to the Actual Temp' Conditions present within the Eng' ~ 

        Let's Surmise ~ If WW Actually Lowers Heat Transfer, thereby Leaving The Heat in the Eng'Metal & also Being LessAble to Transfer the Heat that it is

able to collect to the Temp' Sensor, It Would Appear To Us, Via the Temp'Gauge, that WW Was Indeed Keeping the Eng' Cooler when in Actuality it Would 

Only be keeping the Coolant Cooler ~

        Yet Another Thing to Consider > The ECU makes Its Educated Guesses as to the Conditions In & Around The Combustion Chamber, in part, from Temp'

Info It gets from the Coolant Temp' Sensor ~ So ~ If WW Does Alter the Heat Transfer Ability of the Coolant, Up or Down, That Temp' Info Could Indicate to

the ECU that the Conditions In & Around The Combustion Chamber Are Not What They Actually Are ~ That Could Get Confusing to the ECU if Coolant Temp

was Telling it it Needed to Go Rich & The O2Snsr was Telling it it Needed to go Lean (or VisaVersa) ~
