that´s simple
at ALL gen1 (and gen2 better too and at ALL water cooled motors too)
always have a look / an eye on the measuring surface of the feeler if it is shining clean / if not (as usual
) clean with 1000-2000 sandpaper
thatfor you have to put it out
- best while replacing the coolant.
ok at the gen2 it is a very tricky job because its feeler is only hard to get reached / turned out & in
because it´s hided LH under the throttles and behind lots of wires.
generally said:
- if the surface/measuring area isn´t clean the feeler measures the wrong temperature, the fan starts later and later and the coolant temp rises to .....
- by that also the pressure in the water based system rises to deathyfying bars
- what in the end may destroy / blow through the head gasket
- what then can! be seen by watermarks inside the cylinder.
that all the movement of the feeler from radiator to the RH pipe/hose and
its cleaning (over time a kind of dirt layer forms on the measuring surface, which then becomes a kind of insulation and falsifies the measured values) prevents a very lot.
and
if the gasket hasn´t been blow yet the movement to "the right" can bring (and keep) the pin in your temp.-gauge in the odo back to middle and to stay there,
even if you have 39°C outside AND stop ´n go in a traffic jam
what i experienced some years ago exactly that way !
"the temp.-pointer stayed in the middle as if been stopped by a nail."
