1. Core: The core is the main section of the radiator, typically consisting of a network of tubes and fins. The coolant flows through these tubes, dissipating heat into the surrounding air through the fins.
2. Inlet and Outlet Tanks: These tanks are located at either end of the radiator core. The inlet tank receives the hot coolant from the engine, and the outlet tank directs the cooled fluid back into the engine.
3. Radiator Cap: The radiator cap is a pressure-release valve that maintains the optimal pressure within the cooling system. It ensures that the coolant does not boil over by allowing excess pressure to escape.
4. Thermostat: The thermostat regulates the flow of coolant based on the engine temperature, ensuring that it operates within the ideal range.
5. Coolant Reservoir: This is an overflow container that collects excess coolant from the radiator, which is then reused when needed.
6. Cooling Fans: These fans help to dissipate heat from the radiator by drawing air through the core, especially when the vehicle is stationary or moving slowly.

1. Overheating Engine: If the engine temperature frequently rises above the normal range, it could be due to a malfunctioning radiator.
2. Coolant Leaks: Puddles of coolant under the vehicle or a noticeably lower coolant level could signal a leak in the radiator or associated components.
3. Discoloured Coolant: Coolant that appears rusty or has debris indicates contamination and may suggest internal corrosion.
4. Low Coolant Levels: Constantly needing to top up the coolant could imply a leak or inefficiency in the cooling system.
5. Steam from the Bonnet: This is a clear sign of an overheating engine, often caused by a radiator problem.
6. Strange Noises: Gurgling or knocking sounds from the engine area can indicate trapped air or coolant circulation issues.

1. Prevents Corrosion: Fresh coolant contains inhibitors that prevent rust and corrosion, which can damage internal components of the radiator and engine.
2. Enhances Cooling Efficiency: Clean coolant ensures optimal heat transfer from the engine to the radiator, maintaining the engine’s performance.
3. Reduces Overheating Risk: By removing deposits, a flushed system allows the radiator to operate effectively, reducing the likelihood of engine overheating.
4. Extends Component Life: Regular maintenance, including fluid flushing, can prolong the life of the radiator and other cooling system parts.
5. Improves Fuel Efficiency: A well-maintained cooling system helps the engine run smoothly, improving overall fuel efficiency.
