My temperature gauge moves down to the cold setting then back into normal range. Not sure if it's the Thermostat or something major. If it's the thermostat how can I replace it myself.
Do you
have the same problem?

Replace the thermostat-start here

Drain the engine cooling system so that the engine coolant level is below the water thermostat.

Disconnect the upper radiator hose from the water hose connection.
Remove the three water inlet connection retaining bolts. Remove the water hose connection.
Remove the gasket and water thermostat from the water hose connection. Do not reuse gasket
