Coolant boiling, no overtemp on gauge.

2013 Cruze 1.4L turbo. Coolant is boiling out of reservoir when running. The gauge never shows any indication of getting too hot. Thermostat is new, new reservoir tank and cap. Not leaking any coolant anywhere, only when it boils over. Passenger side going into the radiator the hose feels cold, driver side of the radiator hose is really hot. Compression check was good, cylinder leak down test was good. I’ve vented the coolant system properly also, any help would be greatly appreciated. Thanks in advance.

Hi, friend.

The problem that your chevy has already happened to me... and it's easy to solve. cooling system has air and that is why the passenger side hose is cold and the driver side hose is very hot.
you only have to remove the air that the system has and you have to do it in the following way: you must loosen the screw on the upper part of the thermostat and when you do it you will hear the air come out, you must wait until it pours a little coolant and with that is enough, then you tighten the thermostat screw again and start the car and wait for the thermostat to open. You will notice when you open the thermostat that the hose on the passenger side will get hot and the radiator will get hot.
lucky friend.
