When should Chevrolet Blazer spark plugs be replaced?

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 Chevrolet’s recommendations.

What do I do if I see a pool of liquid under my Chevrolet Blazer?

Don't ignore puddles of fluid under your Chevrolet Blazer. 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 Blazer 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 Chevrolet Blazer

Is it time for an engine tune-up? If you're the type of driver who waits for something to go wrong with your vehicle, now is the time to work on that habit, especially if you want your 2003 Chevrolet Blazer’s engine to last for a long time. Regular engine tune-ups can optimize your Blazer’s power on the road. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by Chevrolet, you’re taking vital steps toward keeping your Blazer’s engine running smoother, longer.

Routine Engine Tune-Up Service for Your Chevrolet Blazer

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Chevrolet Blazer 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 Blazer. 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 Blazer. The result? Restored fuel system performance. Consider this when choosing a tune-up service for your Blazer: your vehicle’s maintenance record and mileage can determine which service is best. 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.
