    Q:
    How to check and replace a Thermostat in a cooling system on Saturn LS? Posted by Marybelle L.
    A:
    Before replacing the thermostat, inspect the coolant level, drive belt tension, and temperature gauge operation. In 2004 models, remove the exhaust manifold heat shield, drain the coolant, remove the thermostat cover, and replace the thermostat. For V6 models, remove the intake manifold, and disconnect the radiator hose.
