Its right below the air box. you will see the bottom radiator hose hokked up to it. the cover/housing is held by 3 bolts. whole bunch of coolant will come out when you take off the housing, so hae a drain pan ready right under the transmission. good luck.

It should be located where the lower radiator hose connects to the engine, and there you should find the thermostat housing. Be sure when installing the new thermostat that the spring side of the thermostat is installed towards the engine.

After you change the thermostat you might have to remove the upper radiator hose from the radiator to pour coolant back into the block, or the engine might not have any coolant getting into it until after the thermostat has opened up, and by then it would be too late and the engine will over-heat. Also, be sure to bleed the trapped air from the cooling system by using any bleeders in the cooling system.

Nissan sentra 1994 use termostat

if you're referring to the thermostatic valve in the coolant line, then yes, yes it does have that. it's located at the end of the upper radiator hose (return line) close to the engine. it's inside of what may look sorta like an elbow pipe.

I need to change out the thermostat on 1997 Nissan Sentra.

The thermostat is located near the back left of the engine if you are looking in with your hood open. It is inconveniently located next to several other hoses and wires. Your best bet is a racheting screwdriver with a 10mm socket. It is accessible from the top side. If you replace the thermostat and you experience over heating, it is most likely just air trapped in the housing. Run your car and warm it up, let it cool down, open radiator cap and add coolant. Repeat a few times and that should purge the air.

Find the big hose that comes out of the top of the radiator and follow it to the engine and that is where the thermostat is located. My advice is to be sure to get a factory thermostat and rubber gasket as it makes installation much easier. I have done it both ways and the factory one is easier to install.

Follow the bottom hose around the back of the engine and over to the passenger side. This hose ends up almost directly behind the front/top hose (where the thermostat should be...but that would be too easy). Unbolt 3 bolts holding the housing on, pop off the housing, and the thermostat should just pop right out.
