There was a crack at the bottom of the tank of the 300SD. A quick RTV patch seems to be holding. FWIW, the SD runs at a lower system pressure than the other cars if the cap rating is any indication.

95 S420
91 300SE
87 300SDL
83 300SD

In the 560SEL there is in fact 2 expansion tanks. There is one above the left passenger tire w/rad cap on it, and another overflow reservoir in the wheel well. It can only be seen if the inner liner is removed with about 10 bolts. I ended up ordering a new expansion tank from fastlane, just because it's so damn hot here in Arizona.!!!
