Comment 1
Tried that and replacing the thermostat and the sensors was not an option on the repairpal estimator. My check engine light has been coming on and when they did the diagnostics it said that my engine was at 72 degrees celsius (I drove it over 40 minutes and in in the mountains). -

Answer 3
The thermosstat in under the intake manifold on the top of the engine. The engine should not have to be removed, although, the thermostat is electronically controlled and is an expensive part.( A couple hundred dollars i think.) Are the fans running constantly? If so, try replacing the temp sensors first for approx $20.00-40.00 ea for parts. There are two.. Also you might want to try disconnecting the battery for a minute and see if the problem goes away. -
