To remove the thermostat you first have to remove the throttle body, it is on the top of the motor on the right it has one bolt and two nuts holding it down. When you remove the throttle body disconnect the air intake tube and make sure all hoses and electrical connectors are removed, the throttle cables do not have to bedisassembled to remove the throttle body. Move the throttle body up and away from the intake to gain access to the thermostat housing. Make sure you have something under the upper radiator hose to catch the coolant and loosen the hose clamp and remove the hose from the housing. the housing has two 13mm bolts holding it down remove them. If the thermostat doesn't come out by hand use some pliers to pull it out. Make sure the rubber gasket on the thermostat comes out with it. Also when you put in the new thermostat make sure it has a new gasket on it. If the thermostat and gasket come separately make sure you put the gasket on the thermostat with the pointed edge facing the engine block. Make sure you have a good throttle body gasket and it wasn't damaged in disassembly Reassemble in reverse of disassemble make sure all hose clamps are tight and electrical connectors are connected. Finally top off the radiator reservoir. P.S. don't try to remove the exhaust pipe on top of the engine to get to the thermostat bolts, it is impossible to get off unless you remove the exhaust manifold not worth the hassle the throttle body is easier to remove. Good Luck
