Nice write-up. You seem to be referencing another tutorial on how to drain, but there's no link. And given the number of problems people have had getting all the air out, I can't help but think there's something missing on the refill.
How-To: Replace 2011-2016 Cruze 1.4L Coolant/Water Outlet
How-To: Replace 2011-2016 Cruze 1.4L Coolant/Water Outlet
Overview:
The coolant/water outlet on the 1.4L Turbo engine has a high rate of failure and typically begins to leak at the joint between the water outlet and the recovery tank hose. The repair involves replacement of both the water outlet and the recovery tank hose. The two should be replaced at the same time.
Tools Required:
- E10 Socket w/ ratchet
- Flathead screwdriver
- In-lb torque wrench (Available on Amazon.com)
- Hose clamp pliers (Available on Amazon.com) (Note: some people try to use pliers for these clamps, but doing so makes the job significantly more difficult. I recommend picking up this tool.
- A clean 1+ gallon bucket
Parts Required:
25193922 Coolant/Water Outlet (Available on Amazon.com)
13251447 Recovery Tank Hose (Available on Amazon.com)
Procedure:
Unless a coolant flush has been performed recently, it would be a good idea to flush the cooling system when this part is replaced. Begin first by draining the coolant, using the following tutorial: https://www.cruzetalk.com/forum/129...uze-antifreeze-coolant-flush.html#post2740610
Note: you will see some extra oil hose in this tutorial that go to my bypass filter. You will not have these hoses on your car, so don't be alarmed if you don't see them.
Remove the clip holding the recovery tank hose onto the water outlet and pull the recovery tank hose out.
Separate the recovery tank hose from the retaining clip shown here:
Using hose clamp pliers, remove the hose clamp at the connection between the recovery tank hose and the coolant reservoir, and remove the hose with a twisting motion.
Using hose clamp pliers, slide the hose clamp down the hose shown here, and remove the hose from the water outlet.
Disconnect the throttle body wire by sliding back the locking retainer (you can use a flathead screwdriver). Using a flathead screwdriver, loosen the intake hose and remove it from the throttle body as shown below. Not shown in this picture, I also removed the wiring connector from the sensor mounted to the top of the intake tube.
Disconnect the O2 sensor harness. You don't absolutely need to disconnect this, but it makes your job a bit easier to do so. There's a plastic retaining clip that you need to slide upward at the same time as you pull outward. This took me a bit of time to get off, but a bit of wiggling and pulling the retaining clip upward and it eventually came loose.
Using hose clamp pliers, slide the hose clamp down the radiator hose, and remove the radiator hose from the water outlet.
Disconnect the wiring connector that goes into the water outlet.
Using hose clamp pliers, slide the hose clamp down the heater core hose, and remove the heater core hose from the water outlet. This will be located underneath the throttle body.
Using the E10 socket, completely loosen the three bolts holding the water outlet.
Remove the water outlet. On mine, the gasket was stuck to the cylinder head. Remove the gasket, and wipe off the surface of the cylinder head to ensure it is free of debris.
Install the new water outlet and torque the E-10 bolts to 71 INCH-POUNDS.
The new recovery tank hose has a retaining clip on the end of the hose. Remove the retaining clip as shown with a screwdriver:
Reconnect all of the hoses and wiring connectors. Don't forget to put the retaining clip back onto the recovery tank hose once reinstalled.
Refill the cooling system through the coolant reservoir.

Here are some things I'd like to add after doing the water outlet myself. Perhaps they can get merged into the main write up.
You may be able to skip removing the white/purple/black throttle body wire (mine didn't come off easily). It seems the only reason to remove it is to reach the throttle body intake hose clamp. I just reached a screwdriver around the wire to disconnect the clamp.
I REALLY wish there was a way to remove the throttle body intake hose since it's always in the way. I rotated it 90 degrees counter clockwise and wedged it in front of the engine. I don't recommend doing this because it's really stiff and you'll be putting a lot of torque on it, so do it carefully if at all.
The blue O2 sensor wire has a junction which is connected to the top of the water outlet by a clip. Disconnect it by sliding the boxy junction down off the clip.

As XR described, you can disconnect the junction with the "plastic retaining clip that you need to slide upward at the same time as you pull outward." Here's a picture of that process.

Even though you've drained coolant from the radiator, there's still about one cup of coolant in the engine. When you remove the water outlet, that coolant will dump out everywhere. One option for catching that is to have a large plastic sheet or tub under the engine since it will drip down from the front and back of the engine. A better option is to lay some clever plastic sheet under the water outlet, catching and diverting the coolant to a cup under the car, then carefully remove the water outlet sensor so the coolant flows out its small hole.
After removing the water outlet, you may need to take the O2 sensor wire clip from the old outlet and move it to the new outlet. Use pliers to press in the wings on the back of the clip, then push it out through the hole. Be careful, it may be fragile due to age. Insert it into the new water outlet. To reattach the O2 sensor wire, slide the junction on to the clip up from the bottom.

If you are talking about the cap o-ring, just replace it.
