2014 LT program car, Pull Me Over Red, 1.4T Auto
Welcome Aboard!So I’ve recently been having issues with my Cruze .. in January I got the “AC off Due to high Engine Temp” message … got the code read and it was my thermostat . Replaced that and everything was “fine” … couple months down the road had to replace PCV and MAP sensors ..
About a month ago I noticed the my Valve cover and gasket were bad .. the noises it was making were horrible … replaced that and once again I thought I was fine . Fast forward to Two weeks ago I noticed when I was on the highway I loss acceleration and my car felt like it was about to die .. but no CEL. I quickly decided to turn off of the highway and pull over at that time I noticed white smoke and instantly thought my head gasket was gone . I found it to be the lower radiator hose had a leak and it was under pressure causing coolant to spray on hot parts of the engine hence the white smoke . I fixed that and my mechanic bleed the lines . No issues and this weekend I got the A/C off due to high engine temp message again but my car wasn’t overheating nor did I have a check engine light . But I noticed the temp needle would float between the C and the middle mark .. still no overheat . I decided to change the engine coolant temp sensor (I am aware that there is two in this vehicle im just trying things here lol ) and the needle still floats around but no CEL or A/C message .. any ideas on what I should do now ?

Make sure you have properly "burped" the system. This is a brief How-To care of Dhpnet:
1- close the radiator drain plug.
2- lower the vehicle
3- vehicle should be level
4- Loosen the vent screw on the radiator
(vent screw is located at the top, right (passenger) side of the radiator)
NOTE: Close vent screw when coolant begins to flow from the vent screw.
5- Add a mixture of 50/50 DEX-COOL antifreeze and clean drinkable water to the bottom line of the bleed nozzle on the coolant surge tank. When the coolant level stabilizes, add enough coolant to reach the bottom line of the down pipe hole.
6- Start the engine. After the engine starts, verify that the coolant level reaches the bottom line of the down pipe hole.
7- Install the surge tank cap
8- warm up the engine. Run at 2,500 RPM until the engine cooling fan turns ON.
Note: If the heater core has been replaced, let the engine run for 2 minutes at 2,000-2,500 RPM. This ensures complete venting of the cooling system.
9- Turn the engine OFF and allow the engine to cool down.
10- Remove the surge tank cap.
11- Check the coolant level and fill to the COLD mark if necessary.
12- Inspect the concentration of the engine coolant, using GE-26568 tester.
13- Rinse away any excess coolant from the engine and engine compartment.
NOTE: After a test drive let the engine cool down and check the coolant level again. Adjust the coolant level to the COLD mark if necessary.
If it still is giving issues it is time to check the sensors.
