I picked up a 2000 2.7 986 Boxster a few months ago, its been a great car bar the fact it slowly looses coolant. I took it to a local garage that I know well, they diagnosed that the water pump needed replacing and did so. However it is still loosing coolant, albeit slightly slower. It is booked back in, in a few days with this garage but I wanted to do some research of my own first.

It looses about 1cm on the meter on the side of the expansion tank in the rear boot over the space of about a month. The rear boot stinks of coolant after the car has warmed up and you can smell it sometimes if you drive with the windows or roof down too.

I pulled away the carpet to check for an expansion tank leak, but was all bone dry and seemed fine. I do have some condensation above the expansion tank on the inside of the boot lid? I wondered if this was normal or maybe the lid isn't sealing properly? Other than this im really hoping its not the head gasket or something bad like that....

Thank you for any suggestions.
