On this model the thermostat can be found by following the LOWER radiator hose to where it attaches to the engine. The hose is typically attached to a fitting behind which is a gasket and the thermostat. The gasket needs to be replaced when the thermostat is replaced.
General procedure: Make sure the engine is cool. Loosen hose clamp where lower radiator hose attaches to engine - pull forward. Place clean pan under hose to catch coolant that might spill out. Pull hose off. Catch coolant in pan. Remove bolts on the fitting that the hose was attached to. Remove gasket. Remove thermostat (note how it was positioned and which side was facing out before removing -- there may be an alignment notch). Install the new thermostat (the way the original was sitting,with the little "barbell" at 12:00) and gasket. Re-attach hose fitting w/bolts. Re-attach hose and clamp. Put coolant that spilled out back in radiator. Start engine and allow to warm up and check for leaks.
Note - If you need to remove your alternator so as to access the nuts holding the thermostat cover remember to disconnect Battery before removing the alternator leads to prevent shorting.
