Can you run a 2003 Jeep liberty sport without a thermostat?

Yes, you can run a 2003 Jeep Liberty Sport without a thermostat, but it's not advisable. The thermostat regulates the engine's temperature, and without it, the engine may run too cool or too hot, leading to potential damage or inefficient performance. Additionally, the lack of a thermostat can affect the vehicle's heating system and overall fuel efficiency. It's best to replace a faulty thermostat rather than remove it entirely.
