What happens if my Jaguar XJS spark plugs fail?

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?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

Are some driving habits better for my Jaguar XJS engine than others?

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.

Tune Into Your Jaguar XJS

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 1989 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, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by Jaguar, you’re taking vital steps toward keeping your XJS’s engine running smoother, longer.

Jaguar XJS Engine Tune-Up Services

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1989 Jaguar XJS. One option is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. The second service focuses on your XJS's filters, specifically replacing the air filter and fuel filter. 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. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your XJS's mileage and maintenance history can uniquely impact its tune-up needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
