Can you run your 2001 Malibu without a thermostat?

Yes, you can technically run a 2001 Malibu without a thermostat, but it is not advisable. The thermostat regulates engine temperature, and without it, the engine may run too cool, leading to inefficient fuel combustion and increased emissions. Additionally, running without a thermostat can cause the engine to take longer to reach optimal operating temperature, which may result in performance issues and potential engine damage over time.
