When should Chevrolet Trailblazer EXT 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 do I do if I see a pool of liquid under my Chevrolet Trailblazer EXT?

Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.

What do hard starts and stops do to my Trailblazer EXT engine?

You can make your driving habits more engine-friendly. Hard starts and stops can increase the stress on engine parts, especially over many years. Boost your fuel economy and care for your engine by using gradual, smooth starts and stops instead.

Chevrolet Trailblazer EXT Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Chevrolet Trailblazer EXT engine tune-up services. The standard Firestone Tune-Up is one service option. The standard Firestone Tune-Up includes new spark plugs (and installation!), a thorough inspection of engine components, and a lifetime parts warranty*. A second service option replaces the air and fuel filter in your Trailblazer EXT. 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 Trailblazer EXT's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Keep in mind that your Trailblazer EXT'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.
