hey guys, as the weather gets cold, ive noticed that the cavy wont pass the 150 degree mark on the temp gauge. i replaced head gasket and water pump earlier this year but have not had any overheating issues or not reaching normal operating temperature until then. i have to drive the car for about an hour before it gets to normal temp. Could it be the thermostat? that would probably be the easiest and cheapest thimg to replace. car has 50k miles and its an 03 5speed. any suggestions?

I would check if the fan is working all the time keeping the engine cool if it is not then yes probably the thermostat stuck open or too low in degrees.

I would say the theromstat is stuck open. I would go ahead and replace that, and you should be good to go.
