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.

Knock sensors are always in contact with the block near the crank. Call the dealership and speak to parts department and they can tell you right where it is on your vehicle by the vin.

Set park brake..,wear safety glasses.., Raise truck front suspension and place on strong Jack stands for space..Or else crawl under it...The sensor you speak of is normally mounted above the oil pan in the engine block...The oil pressure sensor is normally at the center of block just above the oil pan..However there should also be a crank sensor but it will not be in the center of block....It should be at the rear of engine..cam sensor should be at front of engine...Look at passenger side of engine..

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.

This belt should be under the covers that are in front of the engine. I must caution you that the belt is not placed exactly in the correct position you may have engine failure.

The fuel filter on the Cruze is underneath the car on the passenger side. To access it:
• Remove the aerodynamic housing
• Keeep an oil pan underneath to catch the residual fuel
• Use a wrench to open up the filter, and once you see the O ring, start unwinding by hand
• A housing will drop out with the fuel filter-put some pressure, and you can remove the fuel filter.

Any good parts store sells them and just about any service center should be able to install one for you.

I assume you have a 6.6L V-8 installed in the truck. If so, the block heater is located on the Right Side of the engine block in the center Freeze Plug boss.
