The coolant system is a closed-loop system designed to regulate engine temperature. Think of it like the circulatory system of your car. The main components include the radiator, coolant reservoir, water pump, thermostat, and various hoses and tubes. Coolant circulates through these parts, absorbing heat from the engine and releasing it to the environment.

1.1. Key Components of the Cooling System

• Radiator: The radiator is where the coolant cools down. It's usually located at the front of the car and looks like a series of tubes and fins.
• Coolant Reservoir (or Overflow Tank): This tank holds extra coolant and allows for expansion and contraction of the coolant as the engine heats up and cools down.
• Water Pump: The water pump is responsible for circulating the coolant throughout the system.
• Thermostat: The thermostat regulates the coolant flow. It opens and closes to maintain the engine's optimal operating temperature.
• Hoses and Tubes: These connect the various components, allowing the coolant to flow.

1.2. The Coolant's Role in Engine Health

Coolant performs two primary functions:

• Heat Transfer: It absorbs heat from the engine, preventing overheating.
• Corrosion Protection: It protects the engine components from rust and corrosion.
