if you are able to take it so, then put it in a pot with water, turn up 2 a boil...if ur "stat" opens that's good.....if not..bad.....and it should reclose when you let it cool off...

As far as I know this works.

Start the engine cold and make sure you have enough water (cold) in the radiator to see it after the cap has been removed.

Start the engine and let it idle. Put the tip of your finger into the water in the radiator.

After the engine begins to heat up the thermostat's function is to open and allow the water to flow through the block. When this happens the water will suddenly get very warm. If this doesn't happen the Thermostat is either bad or the water pump isn't working.
