What are the requirements for a Class 4 MOT test, specifically concerning cooling systems?

A Class 4 MOT test evaluates a vehicle's condition and performance to ensure it meets legal standards for road use in England, Scotland, and Wales. While specific requirements regarding cooling systems are not explicitly mentioned in the provided context, they are still crucial components of a vehicle's overall health and safety.

For engine cooling systems specifically, it is important to check that all essential components, such as radiators, coolant hoses, and fans, are present and functioning properly. Leaks in the system can lead to overheating and potential engine failure, so any leaks or signs of damage should be addressed before a MOT test. Additionally, ensuring that the cooling system is clean and free from debris will help maintain optimal performance.

The DVLA (Driver and Vehicle Licensing Agency) provides guidance on vehicle maintenance, including engine cooling systems, which can be a valuable resource for understanding specific requirements related to your vehicle's make and model.
