I need to replace the termastat- Where is the termastat and how is it taken out?

Follow the upper radiator hose from the radiator to the engine. The hose will be attached to the thermostat housing which is fastened to the engine with two bolts. While the engine is cold, remove these two bolts and lift up the housing to expose the thermostat. Replace the old thermostat with a new one. An auto parts store employee can help you purchase the correct thermostat for your particular application. When you install the new thermostat, be sure to use the rubber gasket that comes with it. Make sure you don't put the new thermostat in upside down. Sounds silly, but it does happen. Bolt the housing back down, careful not to over tighten the bolts since they most likely will be going into aluminum. Replace any antifreeze that may have been lost with a 50/50 solution of antifreeze and water. You can buy this already premixed by the gallon wherever you buy the thermostat.

THE THERMOSTAT IS INSIDE THE WATER PUMP HOUSING. WHICH HAS WATER PIPES CONNECTED AND TAKES ITS DRIVE POWER FROM THE ENGINE DIRECT.YOU HAVE TO DISCONNECT THE RUBBER PIPES AND UNBOLT THE WATER PUMP OFF THE ENGINE BLOCK.THEN IT COMES APART AND THE THERMOSTAT IS IN SIDE ODD LOOKING THING MAKE SURE TO REPLACE ANY GASKETS IF THEY ARE WORN AND RESEAL IT IN REVERSE ORDER TO REMOVAL.GOOD LOOK FIFTYCALKID
