there has been a recall on some year cruz about coolant leaks. Check with NHSTA.gov to see if you are included. If not you will have to replace housing hoses and any plastic connections around thermostat housing that carry coolant.
Chevy Cruze Antifreeze or coolant leaks typically appear in the thermostat housing of affected vehicles, though it can also leak from the recovery tank house or the throttle body heater inlet pipe in cars with 1.8L engines

Hello Kamran, Your vehicle output speed sensor is located on the transmission tail housing. You can find some images by searching "Google" - 2011 Chevy Cruze Output speed sensor location.

My experience has been causes for over heating was.
leak and low coolant, fan not running if you have 2 fans one come on when A/C is turned on the other comes on when engine reaches operating temp. I have had thermostat stuck closed, radiator cap not sealing, fan fuse or relay, temp sensor not working temp sensor could keep your fan from coming on, I have also had to change a couple radiator but it was due to leak. I have heard of some where radiator was blocked up, I think those were issues of stop leak was used for many years.

Error codes are multiple digits not single.

Scanning/Retrieving codes gives an Automotive Technician basic info......Usually with multiple possible scenarios for the cause of said code(s).Throwing parts at an improperly diagnoised vehicle is what you are now facing....Time for a pro.

Without being able to be there to point it out, I'll attach a link and picture to help show where the actuator is located. It's on the right side of the heater housing, under the dash.

It should look like this:




Here is an exploded view of all heater parts.
The actuator will be part # 45 in the diagram.
