Help all .
I am having some problems with the Temp Gauge in my truck . It will sometimes go from 1/2 way to all the way in a split second .
I then stop and get out and check with my non contact thermometer . and it ant the case !!! I just for fun replaced the thermostat and temp sender . But it still not playing nicely
with the other bits . Any ideas . Thinking of pulling the dash and sending away for test and repair .
