Mostly, if you suspect that the thermostat is faulty, it is more cost effective to purchase a new one as they are not very expensive. To check remove first of all the thermostat. Look for excessive corrosion or damage on this device. Replace with a new one should either condition occur. Then put it in water 25° hotter than that stamped on it. Since most Chevrolet V8 and V6 engines have thermostat at 195 degrees, the temperature of water will be just about 220 degrees Fahrenheit. In this water that must be well stirred, then submerged, its valve should open entirely. Remove it by using a piece of bent wire and then put it in water which is 10 degrees less than the figure indicated on its body. In most cases cooler water temperature should read about 185 degrees Farenheit. At this temperature, fully close thy valve on thy thermostat. Reinstall if satisfactory or buy another like-temped one for the purpose of installing.
