So this is my first winter with the Mystique.
over the summer I watched the temp gauge hang uncomfortably warm, but did some searching and found thats normal.
lately as the temps have been around freezing, my temp gauge dosnt come off of cold unless its getting some rpm's, like 2k. driving in trafic it seems ok untill I turn the heat on then the gauge quickly drops to cold again.
is this normal for the ztech?
could I have a worn waterpump impeller?
:confused:
reciently changed the t-belt w/goodyear+ motorcraft thermostat

my Zetec always seemed to run fairly consistant, unless in traffic in the summer. Original water pump and all. Get a scan tool and watch the coolant temp live, that will let you know what is going on.
 
ok watching the data,
gauge dosnt move into normal range until 175
pointed at R 201
blower fan on high and it drops to 187 under N
 
sounds like you just need to replace the sensor for the gauge as those temps sounds about normal.
