Remove the clamp -1- and then remove the coolant hose -2- from the coolant thermostat housing.

Remove the bolts -arrows- and remove the coolant thermostat housing with the thermostat from the engine.

Clean the sealing surface for the O-ring.

Replace the O-ring and lubricate it with coolant.

Install the coolant thermostat housing to the cylinder block and tighten the bolts evenly to 15 Nm.

A lot more involved than the above "text" implies.

Thank's for adding the vid links Thomas. I'm sure though once he looked under the hood he would have seen that the steps I posted were more than meets the eye.

Have you check that you are actually overheating? The CTS is at the rear of the cylinder head

Test the coolant temperature sensor -hot and cold this will tell you something

It's farfromgroovin.

This is a job that is more than 3 hours for a pro to do. The engine has to be placed into a service lock position that entails removing the front bumper.

Do you still want to attempt this yourself? There are detailed instructions available if you do.
