I have an 84' Jetta w/1.7L engine. The water temp. needle goes to the
little dot after the LED indicator. While idling, the needle goes a hair
above that and the fan comes on and the needle drops back to the dot,
and the fan cuts off. The temp sensor/sender is a month old. Is this
gauge behavior correct? The LED doesn't come on while eng. is running.
Here is a ASCII representation of the gauge.

start and end of the thick solid
white lines on the gauge.

yup...thats normal

My Jetta does the same thing

Yep it's normal.

Hey man

Let me be the guy who disagrees here. I dont find it normal, unless
you consider your car running too hot normal. Yes they do run hot, but
yes they aso can overheat and yes they can also catch fire. WIth that
said, will yours catch fire? Probably not. I experienced the same
thing with two of my Jettas. I replced the fan switch with one that
comes on at a lower temp, also I replaced the thermostat with a
"full-flow" model(opens pretty much right away, and not a good
application in really cold weather) I also installed a switch under my
dash that is powered from acc. voltage(turns off when car is off). So
the bypass switch essentially allows me to turn on the rad fan at my
whim, and in the summer I leave the switch on all the time. I also
flushed the rad which is a pain in the ass as there is no petcock from
which to truly drain the stuff out. All in all, IMHO they run too
hot, and it can be 'fixed' or at the least monitored to a better
degree than just hoping its normal.

Just cause you're paraniod, doesn't mean they're not after you
right ;-)

What do you mean by too hot, what's the temperature in degrees? Thermostats
on most older VWs open just about 180degrees with running temps about 190
give or take a few degrees. From memory the fan would come on just over
200degrees. Now if your VW has AC the fan runs 100% of the time anyways as
long as the AC is on.

I replaced mine with a 165 degree 'full flow' as mentioned for
performance driving as my engine is far from stock.


If you want to insult me, save it for email flames. You only show your
ignorance in the subject matter by throwing in your silly little
comments in a group where other people are sharing experiences, not
voicing idiotic opinions and being assholes. BUT since you started I
will retort because I would hate to let a half-wit who knows nothing
unless he reads it from someone else, to get the last word. I have
personally restored from deaths door three mark II jettas and
experienced similar problems in regard to heating in two of them, you
call it paranoid, but it beats sitting on the highway wondering why
your car is steaming away, which is what you basically suggest, again
showing you have no clue and probably have your car serviced and ask
your mechanic all kinds of moronic question so you can post in here.

If you broadened your horizons a little and saved your pennies from
pumping gas you could go to warm cimates and see for yourself the
burned out wrecks of over-heated cars which have caught fire.
ANYWAYS...... I digress....

I was only pointing out that if your car runs 'too hot' (which is a
matter of opinion varied from car to car) then there are steps you may
take to allow your car to run cooler during rush hour stand still
traffic in the hot summers, or other such scenarios.

I have a 165 degree thermo, and yes I installed a manual way to turn
on my fan, as did my friend who races a Porcshe RS America(look it
up). His car was suffering from heating issues as well, and it was his
idea. BUT i guess since he is a german mechanic who specializes in
race cars, you would know better than he and I..... dumbass.

Apologies and thanks to those of you, who like me, just want to share
and learn about their cars, I rarely if ever would reply to something
like this but I wont let some numb nut flame me in here, especially
someone that posts his 2 cents everywhere but never offers any decent
advice.
