Thanks again Scott.

It's been a while since I've used an infrared gun at various points on
the engine. I'll measure the head and outlet at head. Was just being
somewhat lazy.

I was referring to the 'expansion bottle vent'.  That's all there is
on my engine swap.

Good to know the temp II sensor is always inputting to the ECU.

Neil.
