S5 aluminum water pump necks

[Max777]

Have you considered the fact that there will only be an accurate reading in this location when coolant is actually passig directly over it?

Is this not a big issue? Everywhere I could find, most people dont like to put a temp sensor in a location after the thermostat (ie upper radiator hose) because of this.

As far as a purchase goes: Well, i would if I didn't spend $80 on a brand new plastic one from Atkins....
