coolant is vanishing

[jeet]

when the coolant started going down the service adviser said that the radiator has a leak that i cant see and he can.

are there any other reasons for the coolant vanishing?

thanks

Only leak can reduce the coolant level, i hope leak is external and not internal. As internal leak is from engine head gasket and that is one expensive to fix to change the head gasket.

If external, it cud be anyway from small to medium fix like hose leaking, radiator core leaking, thermostat etc.
