The lower hose, under the distributor. Two bolts hold the cover on. Make sure you replace the thermostat with an exact match. The thermostat has a small hole in the thermostat. When installed this hole should be at the 11:00 position.
I would get the replacement thermostat from Toyota, just ask for one from a '91 Corolla.
