The thermostat is behind the upper radiator hose...remove the upper radiator hose and loosen and then remove the two bolts on the outlet (where the upper radiator hose ends) The thermostat is inside that outlet...Another thing to check is if there is water in the oil...If there is water in the oil then it could have a head gasket problem..Did you ever replace the thermostat? If it is stuck then it would also cause overheating...Excessive exhaust backpressure because of a clogged catalytic converter could also cause overheating..Also check belt tension and condition. A loose belt that slips may prevent the water pump from circulating coolant fast enough and/or the fan from turning fast for proper cooling...Another thing it could be is a faulty Water pump -- Any wobble in the pump shaft or seepage would call for replacement. In some instances, a pump can cause an engine to overheat if the impeller vanes are badly eroded due to corrosion or if the impeller has come loose from the shaft. The wrong pump may also cause an engine to overheat. Some engines with serpentine drive belts require a special water pump that turns in the opposite direction of those used on the same engine with ordinary V-belts... Also check the Fan -- With mechanical fans, most overheating problems are caused by a faulty fan clutch, though a missing fan shroud can reduce the fan's cooling effectiveness by as much as 50% (depending on the fan's distance from the radiator) which may be enough to cause the engine to overheat in hot weather or when working hard.

Hi,
The top radiator hose is connected to the thermostat housing, bolted to your engine. It's an easy enough job and isn't expensive. Make sure you get a gasket with your new thermostat.
I hope this solves your problem. Good luck!

SOURCE: 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.

unfortunately these engines are known for this condition and for head gasket failure.with engine cold pressurize cooling system with spark plugs removed.look down into holes with flashlight after about ten minutes.....im betting youll see a puddle of coolant on piston...usually its cyl# 2 or 3.i cant think of any other possibility for system repeatedly airlocking other than a head gasket.good news they are probably one of the easier ones to replace.

Daughters 95 Sentra overheated this weekend. Lost a/c and cruise started to flash.... Could this be a thermostat. She said all fluids looked good and no leaks...


yes, the thermostat could be stuck closed.

I would still flush the system and install new antifreeze at least every 3 to 5 years.

Looks like this 95 Sentra needs servicing.

Good luck to you.

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.
