I have a 2002 GT 3.8L and the temp gauge indicates the engine isn't getting warm enough.
160 is the first line and 210 is the next line with a temp number. There is a longer line in the middle of the two so I figure that is 185.
The gauge is running midway between 160 & 185, therefore I'm guessing it is running about 173 degrees.
I bought a new thermostat and rubber gasket today but it is like 5 degrees outside right now.
Do you think my stat needs replacing & do I need to drain the radiator to do this or do I just unbolt the housing and hope the antifreeze doesn't pool up on the motor and make too much mess?
