Can anyone easily explain how to change a thermostat?

The car is a 92 sentra. I Need to change the thermostat, can anyone easily explain what I need to buy, and step by step how to change it? I know a little bit about cars (I can identify what the thermostat looks like) But really need to fix my car asap without paying someone else to do it. THANKS!!!Can anyone easily explain how to change a thermostat?
You'll need a new gasket along with the thermostat. The thermostat is located where the top radiator hose connects to the engine. There should been a metal housing that you'll have to disconnect, using a socket wrench and probably a 1/4 or 3/8 inch driver. Take out the old thermostat and gasket, clean off any remaining gasket with a putty knife clean it well, make sure you don't get any debris in the opening. Put in the new thermostat and gasket. Tighten the metal housing back up. You should be able to do this without having to disconnect the upper radiator hose. Good luck.Can anyone easily explain how to change a thermostat?
You're welcome. Glad to be of help. Did you do it by yourself?

You need to buy the thermostat and gasket.

Follow the top radiator hose down to the engine, the hose will goto the thermostat cover. There should be 2 bolts holding it on. Take out the 2 bolts and pry off the cover which will be attached to the hose. Pull out the old thermostat, replace with new. Put new gasket on then cover back over the thermostat and bolt it down. Thats it.
Though most procedures listed here are correct the first step is to drain about 1 gallon of coolant from the radiator at the drain plug in the bottom of the radiator, this should be done while the engine is cool. If the fluid is not drained you will have it drain through the thermostat opening when you remove the cover. Also if your engine is overheating you could have a low coolant level, bad water pump, blown head gasket, cracked head, cracked block etc.
Go to the library, and look for a Chiltons car manual. they will have your year and model. and copy the pages. A thermostat will cost you between $3.00 and $5.00. they are not that expensive. If your car is getting overheated, it may be a fan that cools your radiator. You might want to ask a Parts man, if it is the thermostat.
If the temp gets hot when first warming up, then cools down and works fine, then maybe your stat is bad. Or if it doesn't get warm, maybe...

Otherwise, you have other problems that someone said is caused by a stat.
The top radiator hose goes to the engine.

You need to remove that part, it is inside of that.

Be sure you don't put it in upside down,it will go in wrong.

Be sure to clean all the old gasket off before replacing new gasket.....

read the directions.

Good Luck
