Question about 1993 Nissan Sentra 4 Door
I can't see the thermostat. Where is it located and how do I get at it to replace?
The thermostat will be located in a removable housing at the engine end of the lower radiator hose coming from the radiator. It will have two bolts holding it on. It takes a lot of patience to get it on and off, smaller hands make it easier, generally a socket is the best way to go at it.
Drain about 1 gallon of coolant from the radiator
Remove this housing (radiator fluid can drain from this point if you already didn't do it)
Make note how thermostat is installed
Clean both surfaces
Install new thermostat and gasket
Re-fill coolant slowly to prevent an air lock
Start engine and look for leaks
Run engine to normal operating temperature with heater on
Re-check coolant level
Simple as that though it is a pain to get on and off. Let me know how this turns out.

You upper radiator hose connects to a flange w/ 2 screws on the engine. Unscrew the two bolts, i believe it's a 10mm, or a 12mm. Once opened, the thermostat should be there. Keep note of the orientation so you have no problems when putting a new one in.

Trace the upper radiator hose to the mounting area on the intake manifold. Loosen the hose clamp on the manifold end of the hose and remove the hose. Pull the thermostat out of the intake manifold.
