        Replacing the thermostat on a vehicle usually isn't too hard to do. The only difficulty I have encountered when replacing thermostats on some vehicles is accessing the thermostat itself because of other things you have to remove on certain vehicles. Just about all thermostats will require removing a radiator hose connection, and either a thermostat cover housing or in some cases the water pump itself, there are other parts that may need to be removed depending on the type of vehicle you have.
