Your cooling fans may be coming on or you might have a low temp thermostat. Either way, a cool engine is better than a hot engine.
An open thermostat would keep the engine from heating up to normal operating temperature. The sensors effected can only report what they sense. The "check engine" light may throw a code like "P0116" (engine coolant temperature circuit range/performance problem).
There wont be any leaks, the car wont overheat and it will stay in the normal operating temperatures.
If the temperature gauge is reading below normal operating temp after driving a little while it may be that your thermostat is stuck open. I replaced my thermostat and it fixed mine.
That year engine requires a 195 degree thermostat due to the computer system/sensors. It is NORMAL for that engine temperature to run between 195 to 210 degrees depending on the seasons and how you are using it.
If the car is overheating or if the temperature gauge is not coming up to normal operating temperature which is normally half way up the gauge then the thermostat needs replacing. As the water pump should be replaced at the same time as the cam belt every 90,000 miles, you should also replace the thermostat and coolant.If the car is overheating or if the temperature gauge is not coming up to normal operating temperature which is normally half way up the gauge then the thermostat needs replacing.

Not sure if by your question you mean the thermostat opens slow and the engine overheats or if you mean the engine takes a long time to warm up. If the engine is overheating, more than likely the thermostat is stuck in the closed position and needs to be replaced before engine damage is caused because of overheating. If the engine is taking a long time to warm up, the thermostat is probably stuck in the open position and has to be replaced so the engine can reach its normal operating temperature in a shorter time.
Two symptoms of faulty thermostat which would more than likely require replacement of same: (1) engine overheats quickly (2) engine takes too long or doesn't reach normal operating temperature
That is normal, It is a thermostat
If the thermostat is broken in the closed position the engine would overheat rapidly. If it was broken in the open position the engine cooling system would not reach normal operating temperature and the heater would produce only warm air. Take the thermostat out and put it in a pan of water on the stove. When the water gets to around 200 deg F, the thermostat should open. If it doesn't it needs replaced. Observe carefully that you have not installed the thermostat upsidedown.
Ingeneral, the fan will run only if the temperature of the radiator is above the normal range. If the fan is running, then the radiator must be over temp unless the radiator fan thermostat or it's relay is defective. If the radiator truly is over temp then you have a larger over-heating problem You state the thermostat was replaced. if you replaced the fan thermostat then either the radiator really is over temp and it is doing what it should, or there is a problem with the thermostat-fan relay or switch. If you replaced the engine thermostat that controls the flow of coolent between the engine and the radiator, then that probably wasn't your problem and you should look elsewhere for an overheating cause. I would start by determining if the engine actually is overheating or not. If it is, I would look for coolent system problems like the engine thermostat (if you didn't replace it already), water pump, leaks, scale build up in the radiator, or blockages in the system. If the engine isn't overheating then I would consentrate on the fan, fan thermostat and relays.
No this is not normal. Depending on the color of the smoke, the engine is either burning oil, or the fuel/air mixture is off and the fuel is not burning fully.
In the "Normal" range? Lower than normal could be a bad thermostat Does heat work?
