Latest Insights and Technical Information
As of July 10, 2020, it is advisable to test the hydraulic pump by connecting a 12v power source to the larger connector. Be cautious, as the pump draws a significant amount of current during normal operation. Jaguar vehicles feature two independent hydraulic systems, Hyd-1 and Hyd-2, each with a 6-litre reservoir capacity. These systems are powered by the engine and are crucial for the convertible top’s functionality.
Common Issues and Maintenance Tips
One common issue with Jaguar hydraulic systems is the solidification of hydraulic fluid, particularly in models from 1997 to the mid-2000s. This can lead to blockages in the lines, especially in the valve area. Regular maintenance and fluid changes are essential to prevent such issues.
Maintenance Tip:
Always use the Jaguar-recommended green mineral-based hydraulic fluid for your convertible top pump. This ensures optimal performance and longevity of the system.
Accessing and Refilling the Hydraulic Pump
Accessing the hydraulic pump can be tricky. In certain models, you can remove a back panel to reach the motor. Always check your vehicle’s manual for precise guidance. When refilling, pay close attention to avoid overfilling or using the wrong fluid type.
