Hello I will help you with your question,
The thermostat is buried behind the accessory bracket above the water pump. The upper radiator hose attach's to the thermostat housing. It can be a bear to change unless you have an angle grinder with an extension drive to hold a 2" scotch pad to remove the old gasket material.If you do not have this capability the bracket will need to be removed as the procedure below shows.
Look this over and let me know what further questions you have about this
