What happens if my Mercury Cougar spark plugs fail?

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 Mercury’s recommendations.

What does a puddle underneath my Mercury Cougar mean?

Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.

Are hard starts and stops bad for my Mercury Cougar 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.

Enhance Mercury Cougar Performance with a Tune-Up

Is it tune-up time? 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 1989 Mercury Cougar. Routine engine tune-ups can bring power back to your Cougar. Tune-ups give your engine a boost in efficiency, which can lead to lower emission levels and better fuel economy. When you follow the guidelines specified by Mercury for your vehicle’s tune-up schedule, you’re taking vital steps toward keeping your Cougar’s engine running smoother, longer.

Engine Tune-Up for Mercury Cougar

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Mercury Cougar engine tune-up services. The first 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 Cougar. 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 Cougar's fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Consider this when choosing a tune-up service for your Cougar: your vehicle’s maintenance record and mileage can determine which service is best. If you’re not sure what services are the best fit for your car, let us help! Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.
