This is a 2011 Chevy Cruze 1.4 L Eco with 116xxx miles on it.
The other night I made it home from driving about 30 minutes from work and when I turned the car off I heard some noises. I looked under the hood and noticed it boiling at the tank. I did replace the reservoir a few months back due to the fact it had a crack in it and was leaking coolant. Did a flush and when I added new coolant I burped the system as I was told.
Everything has been fine until that night. I let the car sit over night purchased a new cap and checked the car and the coolant level was low so I topped it off put the new cap and took it for a spin. After some time of driving everything seemed good until at one point I came to a stop and I noticed some smoke. I parked and turned it off and seen coolant on the side of the engine That came from the reservoir which was boiling again.
I noticed as well there was some coolant that leaked from the coolant temperature sensors, but was told that wouldn't have a major issue from the guy at Autozone which he was the one who said replace the cap in the first place stating it could be a pressure problem. Also someone recommend replacing the thermostat so I will be changing that as well as the coolant sensor this week and dumping out the coolant and flushing it again but is there anything I should know about this issue?
Could it be something else or is this the symptom of something else? At this point I'm not driving the car I don't want to cause anymore damage. Also I checked the coolant level now and it's almost empty at the tank. Will the coolant level being low have something to do with the boiling?
