Narrative:
At 400 AGL on climbout I noticed an eng oil temp EICAS message. I then got the QRH in hand ready to be read to the captain. At this time the oil temp was in the caution range. The checklist directed us to retard the throttle slowly until the oil temp returned to normal. It did not; rather the oil temp was now in the red range. The checklist then directed us to [place the] fuel control switch to cut off. Once the engine was shut down the temp steadily decreased. The captain then declared an emergency and he advised ATC that we would need to jettison fuel. ATC cleared us to an intersection to hold and dump fuel. However a level 3 cell was over the intersection; so the captain then requested holding further south to avoid weather. The fuel jettison checklist was commenced and jettison lasted approximately 30 minutes. Dispatch was contacted and advised of our intention to return. The captain advised the lead flight attendant of our situation and told her not to prep the cabin for an evacuation. Passengers were then notified of our situation. Once at max landing weight; we prepared for an ILS approach. The approach and landing were executed and concluded uneventfully. Fire and rescue followed the airplane to the gate and no abnormalities were noted.
