Can you run Ford Mondeo without a thermostat?

Yes, you can technically run a Ford Mondeo without a thermostat, but it's not advisable. The thermostat regulates the engine's operating temperature, ensuring it warms up efficiently and maintains optimal performance. Without it, the engine may run too cold, leading to increased wear, reduced fuel efficiency, and potential issues with emissions. It's best to replace a faulty thermostat rather than remove it entirely.
