Some time ago I had a wheel bolt welded to my metal pipe that bolts
to the water pump with the thought athat some day i'd find a 14x1.5
VDO sending unit for my on top of dash VDO temp gauge.  Now that I've
found a sending unit and it's arrived, I screwed it in last night

The question is; I this an optimal place to measure water temp?  The
factory chose up by the thermostat for their gauge, and I'm noticing
that the oil temp(unit down where the oil filler tube used to be a la
Ken Lewis design) reads higher than the coolant temp.  How does the
oil get hotter than the coolant or is the metal pipe area the coldest
the coolant gets?  I would think being that close to the exhaust and
all that it should read hotter than the oil at least until 15' or so
of highway driving.  Yes, I have a 150C gauge and the complimentary
150C sender, so it's not a mismatch of resistance or whatever.  I
will ocntinue to play with it some more and observe and report back.

Inquiring minds wanna know.
