If you have an automatic transaxle, remove the exhaust manifold. Next, drain the cooling system. Remove the thermostat housing to water pump.
Remove the thermostat housing to water pump feed pipe. Finally, remove the t-stat. Reverse the process to replace.

Here is a picture of the item discussed. Check to make sure the maniflod needs removed to access it prior to removing it.

Let me know if this help, or if you have other questions. Also, make sure you use the same type of coolant as is in the system. If it's Dexcool, DON'T CHANGE IT.
