When should Jaguar XJS spark plugs be replaced?

When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.

What should I do if I see leaks under my XJS?

Don't ignore puddles of fluid under your Jaguar XJS. It could signal a coolant leak, brake fluid leak, or an oil leak. Let any one of these leaks linger and it could cause engine damage.

Are hard starts and stops bad for my Jaguar XJS engine?

Hard starts and stops put extra wear and tear on engine components. Smooth, gradual starts and stops, on the other hand, are a great way to help your engine run better. They can also help maximize your fuel economy.

Enhance Jaguar XJS Performance with a Tune-Up

Is it tune-up time? If you tend to ignore your car until something goes wrong, it might be time to change your ways, especially if you want your 1986 Jaguar XJS’s engine to last for a long time. Regular engine tune-ups can optimize your XJS’s power on the road. They're designed to help your engine start easier and run more efficiently, so you can enjoy improved fuel economy and lower emissions. When you follow the guidelines specified by Jaguar for your vehicle’s tune-up schedule, you can rest assured you’re investing in your XJS’s long-term engine performance.

Engine Tune-Up for Jaguar XJS

The Firestone Complete Auto Care location in your community offers several Jaguar XJS engine tune-up services. One option is the standard Firestone Tune-Up. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. A second service option replaces the air and fuel filter in your XJS. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your XJS. The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your XJS can determine what kind of service it needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
