....clean up the entire area including expansion tank, caps, hoses and radiator and look for areas where there are cracks or splattering

perhaps like ennui mentioned, there's a small small crack somewhere and maybe the water vaporized through the crack when hot...maybe you should get a second opinion from another mechanic...

 

[Ennui78]

Take the car to a mechanic and perform a 'pressure test' on the expansion tank. You may notice bubbling at a crack, or a leak in any of the hoses. That's all I can advise for now, really.

just change the expansion tank and the water hoses.

It time to change it..

Dicky,

This happened to me and bmtroubleyou. When the car overheats the expansion tank will automatically releases the coolant through the cap of the expansion tank. Therefore, after you have let the car cool down and open the cap, you noticed that the coolant is low or during driving the warning indicator appears.

According to Auto Bavaria. The car overheat is caused by water pump failure or termostate jammed. They cannot be certain so they will change both.

Perhaps you can ask your mech to check both of it. Hope this will help a bit.

Cheers
