Q: How do you remove and replace the thermostat in a Cadillac CTS?
A: To remove and replace the thermostat in a vehicle, disconnect the cable from the negative battery terminal and drain the cooling system. On V6 engine models, loosen the radiator hose clamp and detach the hose. Remove the bolt holding the outlet pipe, oil dipstick tube, and engine lifting bracket, then pull the outlet pipe and O-rings. Remove the intake manifold and the thermostat housing fasteners. Press down on the thermostat and rotate it to clear the locking ears, then remove it. Remove the coolant pipe front and rear fasteners, as well as the pipe to thermostat housing fasteners, and remove the pipes from the thermostat housing. Remove the thermostat cover fasteners, detach the cover and thermostat, remove the cooling fan assembly, and disconnect the radiator hose clamp.
