Fixing Leaky Cruise Control Bellows on 1980-1987 Jaguar XJ6 and Most XJS Models
If you own a 1980-1987 Jaguar XJ6 or most XJS models, you may encounter issues with the cruise control system due to a leaky rubber bellows. This component plays a crucial role in maintaining proper cruise control function, and leaks can lead to failure.
Identifying the Issue
The cruise control bellows is a simple rubber piece with two metal end caps. Over time, the rubber can degrade, leading to leaks where the bellows meets the metal caps. If your cruise control is not working properly, inspecting this component should be one of your first troubleshooting steps.
DIY Fix: Sealing the Bellows
- Remove the Bellows: Carefully detach the unit from the cruise control system.
- Inspect for Leaks: Look for visible cracks or separations around the metal end caps.
- Apply Gasket Sealant: Use a high-quality gasket sealant to create a tight seal between the rubber bellows and the metal end caps.
- Reassemble and Test: Once the sealant has dried, reinstall the bellows and test the cruise control system.
Additional Troubleshooting
If sealing the bellows does not resolve the cruise control issue, other electrical components in the system may require testing. Be sure to check the vacuum lines, control module, and associated wiring to ensure everything is functioning correctly.
This simple repair can restore cruise control functionality and help you avoid unnecessary part replacements. Keeping your Jaguar’s cruise control in working order enhances driving comfort and maintains the vehicle’s originality.
