I want to locate and change the thermostat.
The thermostat is easy to find. Follow the upper radiator hose where it clamps onto the engine. The part that the hose clamps onto is a cover for the thermostat. Check the hose and make sure that it's in good shape; if there's soft spots, worn spots, or places where oil has gotten onto it and softened it, you will want to replace it as well. If so, you will want to drain about a half of a gallon out of the radiator first, then proceed. If you're keeping the hose, you can use a clamp and a couple of pieces of metal or wood to clamp the hose shut to keep it from leaking all over. After the hose is clamped, remove the clamp that holds the end of the hose to the engine, then remove the two bolts that hold the thermostat cover on. Remove the cover, clean the area up, making sure it's dry. Lift the thermostat out, and put the new one on exactly as the old one was. It is possible to put it on backwards, and that will cause huge problems. after the thermostat is in place. Taking the gasket that should come with the thermostat, if it's a flat gasket, put a bit of High-temp silicone sealant on it, spreading it thinly over the entire gasket. place the gasket in place, and bolt the cover in place. If it uses a rubber o-ring, replace as well, but silicone is not required. After the cover is bolted in place, reattach the hose, remove the clamp keeping it from leaking, and replace any antifreeze that you may have lost. Moniter for leaks for the next couple of weeks, check when you fill it with gas and check oil.
