Narrative:

At FL370; cruise flight; 'left engine hydraulic pump overheat light' with 'EICAS; left system reservoir full and normal.' shut down pump per checklist. 20-30 minutes later; in cruise flight; 'left hydraulic system reservoir' with 'EICAS left system quantity zero'. Ptu working normal went through all checklist. Declared inflight emergency. On base leg; configured early (ptu status message. Ptu not backing up 'left system' due to no 'hydraulic quantity') manually extended flaps to 20 degrees; manually extended gear. Landed uneventfully with no nosewheel steering. Turned aircraft off runway 14R with differential power and brakes stopped on taxiway and got towed to gate.
