When should Jaguar XJ12 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 does a puddle underneath my Jaguar XJ12 mean?

Don't ignore puddles of fluid under your Jaguar XJ12. 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 XJ12 engine?

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.

Tune Into Your Jaguar XJ12

Is it time for an engine tune-up? If you usually wait until your car has an issue to take it in for service, now is the time to work on that habit, especially if you drive a 1994 Jaguar XJ12. Regular engine tune-ups can optimize your XJ12’s power on the road. Tune-ups help your engine start smoothly and run 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’re taking vital steps toward keeping your XJ12’s engine running smoother, longer.

Jaguar XJ12 Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Jaguar XJ12 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*. Another service option pays special attention to the filters in your XJ12. 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 XJ12's fuel injectors, throttle body, and throttle plate. This can improve your fuel system’s performance (and therefore, your engine’s performance). Keep in mind that your XJ12'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. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
