i need to know how to change thermostat 1994 chevy suburban... i heard its easy but i have never done it before, also wondering if anyone knows why my temp. gauge isnt working and what would make it work?? my car overheated today and i heard i should change the thermostat but i also would like to get the temp gauge working so i know next time there is a problem lol thanks in advance!
 
Can we assume its a 350 V8..the Thermostat can be found at the opposite end of the Top Radiator Hose looking from the radiator, in other words where the radiator hose hooks to the engine. Its a Aluminum adapter plate with two machine bolts. You remove those two bolts after you have removed the hose and you will find the thermostat. Notice how its mounted in there..and replace with a new one with a new gasket.
The Temperature gauge sensor will be on the right side as you face the engine, near the first spark plug. It looks like a brass plug with a wire connected to the center of it...
Both parts are very easy to replace.
