I have a 2013 Chevy Cruze. Every couple days the thermostat raises in temp, when I check the reservoir for coolant it boils over or is empty. Had the thermostat and reservoir cap replaced.

My normal mechanic said he’s not sure what’s wrong (not sure if it’s the truth or he’s genuinely confused).

I used to see leaks underneath the driver side when I would come back to my car, the temps are about 25-33F now so it’s not hot here.

This has been an issue for a while but it’s gotten real bad really recently (1-2 months).

Any advice or recommendations are appreciated, real big car noob. Thank you.
