what is the average operating temp of this car? also, at what temp do the fans turn on
i seem to be running hot yet have not seen the fans turn on. what temp is the fan switch set for? And, what is the average operating temp of the Jetta? mine is running about 195 or so.
Most engines water cooled engines run at about 90 c (195 f). The fan should cut in at about 100 - 110.. I had a 98 Passatt and that ran at a constant 90 so I would imagine that you're Jetta is the same.
your fans turn on when your thermostat opens, which is anywhere between 180 f to 215 f
if your fans are not turning on it may be a temperature switch located on the side of the radiator move the connector around while its running to make sure there is not a bad connection otherwise you could replace it its a fairly cheap part
if you jump the terminals 1-2 low fan speed should occur jump 1-3 high fan speed should occur if this works replace thermo switch on the radiator
