Will it hurt my Jaguar XJ6 to drive with old spark plugs?

Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on Jaguar’s recommendations.

What should I do if I see leaks under my XJ6?

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.

What do hard starts and stops do to my XJ6 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.

Tune Into Your Jaguar XJ6

Is your engine overdue for a tune-up? If you tend to ignore your car until something goes wrong, it could be time for a new way of doing things, particularly if you want to keep your 1991 Jaguar XJ6 in tip-top shape. Regular engine tune-ups can optimize your XJ6’s power on the road. They're designed to help your engine start easier and run more efficiently, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you get routine engine tune-ups based on Jaguar's recommendations, you invest in your XJ6's long-term health and engine performance.

Jaguar XJ6 Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Jaguar XJ6 engine tune-up services. One option is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. Another service option pays special attention to the filters in your XJ6. Specifically, we replace the fuel filter and air filter. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your XJ6's fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Consider this when choosing a tune-up service for your XJ6: your vehicle’s maintenance record and mileage can determine which service is best. 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.
