if your motor is the 3.4 then you dont have to worry bout the exst pipe since the thermostat housing has a slotted hole were the pipe is, but beware that those two 10mm bolts are somtimz very tight so youll probly need little extra leverage, otherwise its simple

first you need drain engine coolant down below thermostat. what engine type 3.8 or 3.4 need to know.the 3.8 engine thermostat housing on top intake follow top radiator hose to thermostat housing.the 3.4 engine you have to remove air filter housing with air inlet duct with mass air flow sensor.you have to remove throttle body with coolant hoses.go to auto parts store buy new throttle body hoses old ones will be hard to remove might have to cut two small hoses also buy new throttle body gasket also. before you can remove throttle body unit you have to remove accelerator cable and downshift cable from bracket bolted to throttle body.once throttle body remove then you can remove thermostat housing bolt remove replace thermostat.

FIRST YOU HAVE TO DRAIN COOLANT LEVEL BELOW THERMOSTAT THEN.TO REMOVE THERMOSTAT YOU HAVE TO REMOVE AIR FILTER DUCT AND MAF SENSOR TOGETHER.HAVE TO DISCONNECT ACCELERATOR CABLE AND TRANSMISSION SHIFT CABLE FROM THROTTLE BODY BRACKET. YOU HAVE TO REMOVE THROTTLE BODY UNIT REMOVE THE SMALL COOLANT HOSES FROM THROTTLE BODY,YOU NEED TO GO TO DEALERSHIP TO BUY THE SMALL COOLANT HOSES ATTACHED TO THE THROTTLE BODY.WHEN YOU REMOVE THE THROTLLE BODY UNIT.THEN YOU CAN REMOVE THERMOSTAT HOUSING TO REPLACE THERMOSTAT.YOU NEED TO BUY NEW THROTTLE BODY GASKET DONT REUSE OLD ONE.IF DO YOU WILL GET A VACUUM LEAK AND HAVE HIGH IDLE PROBLEM.
