Overheated

2007 CHEVROLET EPICA

Hi expert technicians.
I have a Chevrolet Epica 6 cylinders and 2000cc model 2007
Lately I noticed some time the care overheated and the temperature indicator show a high temperature and it lose the water in the plastic container.
When it become cool I refill the water container and it will be OK for about 10days.
I have to keep checking the water level all the time.
When it overheated the water come out from the plastic container cover which works as relief valve.
Please advise what to do?
Thanks.
MSM

If the engine is using coolant and you have no leaks then we need to find out if it is a head gasket.

Let's start with the basics and find out if the system will hold pressure using these couple of guides:

If it holds pressure then we need to get the engine hot and then test it for a head gasket issue.

Here is a guide that will help with this:

You can also use this guide to do a compression test but this is not as definitive as a head gasket test.

Please run through all this info and let us know what you find. Thanks
