thermostat location on 2003 Nissan altima
On a 2000 Nissan Altima, the thermostat is typically located near the engine, at the end of the upper radiator hose. To access it, you usually need to remove the radiator hose and the thermostat housing, which is bolted to the engine. It's advisable to ensure the engine is cool before attempting to locate or replace the thermostat.
No it should fit into the housing along with the thermostat. Try putting the rubber in first, then the thermostat. remember the rubber is malliable so it will conform to the opening, then insert the thermostat
