I was wondering if anyone is having the same problem as myself? Under some semi-hard driving my car temp. gauge will drop from normal to almost cold. Is this something normal??? Does anyone else have this problem??? What could this be???

 

When I was running with the stock thermostat I never saw the needle move once it was settled.

 

yeah...i was having the same problem....the factory gauge just isnt very accurate...
i installed a gauge and now i have a more accurate reading.....

anywhere from 180-140 under hard driving conditions
