What happens if my Lexus LS400 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 LS400?

Don't ignore puddles of fluid under your Lexus LS400. 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.

What do hard starts and stops do to my LS400 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.

Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

Enhance Lexus LS400 Performance with a Tune-Up

Is it tune-up time? If you tend to ignore your car until something goes wrong, now is the time to work on that habit, especially if you want your 2000 Lexus LS400’s engine to last for a long time. Routine engine tune-ups can bring power back to your LS400. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you get routine engine tune-ups based on Lexus's recommendations, you’re taking vital steps toward keeping your LS400’s engine running smoother, longer.

Engine Tune-Up for Lexus LS400

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 2000 Lexus LS400. The standard Firestone Tune-Up is one service option. 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 LS400's filters, specifically replacing the air filter and fuel 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 LS400's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your LS400 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.
