Hi,

Replacing the thermostat isn't too hard. Just make sure to keep all coolant away from animals. It is very toxic.

To get you started, here is a link that explains how to replace an engine coolant thermostat in general. It can be used to help guide you.

If you look at the attachments below, they provide the directions and pics specific to this vehicle for replacement.

I hope this helps. Let me know if you have additional questions.

Take care,

Joe
