Iare both cooling fans supposed to work together on the Jaguar XJ8?

Yes, both cooling fans on the Jaguar XJ8 are designed to work together to regulate engine temperature effectively. The fans typically operate in tandem to provide optimal airflow through the radiator, especially under high load or when the engine is heating up. If one fan is not functioning, it can lead to overheating issues, so both should be operational for proper cooling performance.
