They way my mechanic explained to me was this..."once the water
is no longer surrounding the sensor, the sensor will reflect the air
temp,
which is much lower than the coolant was"...so, that is why my temp
guage 1st spiked ... for 3 - 5 (as the coolant started heating up) min
of
driving, then seemed to return to normal...even though I was really way
low on coolant........The guage does not reflect motor temp, just
coolant
or coolant cavaity (if empty) temp.....And yea, I agree there is a
dampner
factor built into the guage or sensor , so the guage is a bit more
stable........My mechanic told me he has seen the 940t's get so hot
and overheated...all the plastic pieces in the engine compartment
were melted and totaled......and, if you l@@k at my 93 940t...there is
a
hell of a lot of plastic under the hood.....
