I was hoping for the expansion tank issue as well. I searched on "Check Coolant Level" and it seemed about 1/2 were expansion tank and 1/2 were valley pan gaskets. Today is just not my day (I dropped my Blackberry breaking the trackwheel as well. It wasn't when I heard the price of the repairs although that would be a better story).

The tune-up includes spark plugs, filters and I think all of the Inspection II checks.
