I respect Scott's comment but i will decent on this one.
We went the 100% crazy route when we thought my gauge was reading high (7/8)
and sometimes red light on warm days. New sensor, stat, radiator, wiring
check, voltage stabilizer/reguator ect. Finally got the infered gun and
compared locations and temps to my buddies 2.1L and we took exact temp
readings but our gauges showed different data. it's hard to say what is
"dead on" with these gauges. I did tons of research with Bentley, VDO and VW
tech manuals trying to figure out all Ohm readings for a given temp. Lot of
work and poor data out there to find that different resources gave slightly
different Ohm readings for arbitrary gauge readings. I've got the sources
for those interested.
Combine this to a gauge that reacts wide and slow due to the radiator being
so far forward and I've never been a huge fan of the temp gauge on these
things for the often OVERCOOLED vanagon engine.
