Narrative:

Departed aus for las. Climbing through FL210 approximately 95 NM west of aus, flight engineer noticed engine #3 strut overheat light illuminate. He notified me, then pulled out the 'engine strut overheat light' checklist. I had the first officer and flight engineer work the checklist while I flew and worked the radios. After completing the checklist, it was determined a precautionary shutdown of engine #3 was necessary. I declared an emergency, requested a turn back to aus, and requested emergency equipment standing by. I then advised senior flight attendant to inform the passenger. I called for the 'engine failure precautionary shutdown' checklist which the first officer and flight engineer worked. It was then determined we would be over maximum landing weight, so I called for the fuel dump checklist and notified ATC. We dumped approximately 4K pounds of fuel. Notified ATC of fuel dump termination. I then called for the '2 engine landing' checklist. We continued inbound, landed VFR uneventfully on runway 17R aus, taxied to the gate on 2 engines and terminated the emergency.
