    Q:
    How to replace a thermostat in a cooling system? Posted by Customer
    A:
    To remove the thermostat, disconnect the cable from the negative terminal and drain the cooling system. Loosen the hose clamp and remove the hose from the thermostat housing, or the thermostat housing cover with the radiator hose attached if the clamp cannot be accessed and remove the thermostat cover mounting bolts and detach the housing cover.

    Q:
    How can you determine if the thermostat is stuck closed for the 2006 Cadillac DTS? Posted by Customer
    A:
    If the engine runs hot and the upper radiator hose is not hot, it suggests a stuck closed thermostat, which also needs to be replaced.
