I have had to change it 2, and it is a royal pain in the butt. There are two bolts holding the housing on, however the housing is located underneath the throttle plate. so that being you have to remove the throttle plate and even then its a pain in the butt to get to the housing bolts.

Replace the thermostat.
where do i find the thermostat for 99 cavalier
at or near the thermostat housing
The thermostat is located in the thermostat housing at the engine end of the top radiator hose.
weher thermostat locaked for impala 2001
Look where the top radiator hose connects to the engine(water pump).
right on top on the intake. it is where to top radiator hose connects to the motor.
In the connection at the radiatorhose and waterpump Follow the upper radiator hose out of the radiator. When that hose connects to your engine, the thermostat is in there.
Its located under the throttle body or follow the upper radiator hose til it hits a semi round housing. There is 2 bolts to remove it. First you have to drain the radiator fluid of course. I am changing the thermostat right now on my 2001 Chevy lumina and I see I will have to also remove the throttle body to get to the thermostat housing
