Hi Zoran,

Good to know - one data point is better than none!

Since plastic is a poor thermal conductor, the
coolant temperature may not correlate well to
the temp on the exterior of the pipe, where
we can measure it.  So my questions/concerns
when measuring temps include:

-what if it's windy?
-how warm is the engine? (duh)
-what if it's warm outside?  What if it's cold?

Certainly a ~2 degree difference vs. a ~20 degree difference
should be easy to spot, but it's hard to know...  What if
the difference is only 10 degrees, for instance?

I suppose I should get off my butt and wander outside
with the pyrometer and get some numbers, instead of
asking you, right?  :)
