Hi can anybody tell me why my probe when up to temperature (2.5 v6) is leaking water from the top of the coolant plastic bottle please.

Thank you

Now coolant bottle is to the top

The water in it isn't hot just slightly like warm

Now left the car cool and water level has dropped

It will be along the lines of what has been said on Facebook, either the cap near to the expansion tank is leaking, or you have air in the system causing the pressure to build, or a thermostat that isn’t opening.
