The thermostat is equipped with a temperature-sensitive wax or liquid that expands and contracts in response to changes in temperature. When the engine starts and is cold, the thermostat remains closed, preventing coolant from circulating through the radiator. This allows the engine to reach its optimal temperature more quickly. Once the engine warms up to the predetermined temperature, the thermostat opens, letting coolant flow through the radiator to dissipate heat and keep the engine from overheating.

The primary role of tires is to provide safety. They are designed to grip the road, enabling vehicles to accelerate, steer, and stop effectively.

Tires with sufficient tread depth can channel water away from the contact patch, reducing the risk of hydroplaning during rainy conditions. Regularly checking the tread depth and replacing worn-out tires is crucial for maintaining safety on the road.
