A persistent myth among some motorists and mechanics suggests removing a vehicle's engine thermostat will help it run cooler, especially in hot climates. This article debunks that idea, explaining the thermostat's crucial role in engine performance.

• The thermostat regulates engine temperature, ensuring it warms up quickly, reduces wear, and improves fuel efficiency, not just preventing overheating in hot weather.
• Automotive engineers like Christopher Anyembe emphasize that thermostats are designed for internal engine temperatures, not ambient weather.
• Removing a thermostat can lead to increased fuel consumption, more engine wear, and mask underlying cooling system problems, rather than solve them.
