Question about Cars & Trucks
Stuck thermostat can be stuck open (which means engine never gets warm enough, which means heater blows cold and gas milage suffers and maybe check engine lite comes on) or can be stuck closed (which results in overheating). Newer cars have two temperature sensors, one which controls a dashboard display, and another which tells the computer how warm the engine is and the computer adjusts fuel mix. On most cars, it is simple to remove the thermostat and replace it. Once removed, you can inspect it using finger pressure to try to make it open. If at room temperature it is already stuck open, replace it. If it is closed, you can put it in a pan of water (not one you ever use for cooking!) and heat it to 180-195 degrees to see if it opens. BEWARE - some cheap parts store replacement units are of poor quality. As cheap as this part is, use the best you can buy - maybe even from the dealer. Good luck.
