The labor time to replace a thermostat on your 2000 Olds Intrigue, is about one hour. How much it costs depends on the Hourly Shop Rate at the repair facility that you select. Just ask them what their hourly rate is & that will also be your labor expense. Also, cost of the thermostat, around $15.00.

No one would sell the thermostat by itself.
