What happens if my Jaguar XJS spark plugs fail?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What does a puddle underneath my Jaguar XJS mean?

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

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.

How frequently do I need to get my Jaguar XJS fuel injectors cleaned?

The frequency at which car fuel injectors should be cleaned can vary depending on several factors, including the type of fuel used and the driving conditions.

Tune-Ups to Help Your Jaguar XJS Run Better

Is it tune-up time? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, particularly if you want to keep your 1987 Jaguar XJS in tip-top shape. Routine engine tune-ups can bring power back to your XJS. Tune-ups help your engine start smoothly and run efficiently, so you can enjoy improved fuel economy and lower emissions. When you get routine engine tune-ups based on Jaguar's recommendations, you can rest assured you’re investing in your XJS’s long-term engine performance.

Engine Tune-Up for Jaguar XJS

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1987 Jaguar XJS. The standard Firestone Tune-Up is one service option. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus 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). 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.

Where Should I Go for My Jaguar XJS Tune-Up?

Schedule your next 1987 XJS engine tune-up service at Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Jaguar, or make a service appointment if you notice any of these symptoms from your engine: decreased gas mileage, "rough" idling or stalling when stopped, knocking noises in the engine, or a lit up check engine light on your dashboard.

*Ask a Firestone Complete Auto Care teammate about full terms and conditions for warranties.
