Will it hurt my Mercury Cougar to drive with old spark plugs?

Replace spark plugs on time or about every 30,000 miles or so. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.

What does a puddle underneath my Mercury Cougar mean?

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.

Are hard starts and stops bad for my Mercury Cougar 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.

How frequently do the fuel injectors in my Mercury Cougar need to be cleaned?

Tune Into Your Mercury Cougar

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, particularly if you want to keep your 1985 Mercury Cougar in tip-top shape. Routine engine tune-ups can bring power back to your Cougar. Tune-ups give your engine a boost in efficiency, which can mean better fuel economy (a win for you) and lower emissions (a win for the environment). When you take your car for regular engine tune-ups as recommended by Mercury, you can rest assured you’re investing in your Cougar’s long-term engine performance.

Engine Tune-Up for Mercury Cougar

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1985 Mercury Cougar. The first is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. Another service option pays special attention to the filters in your Cougar. Specifically, we replace the fuel filter and air filter. Our third service is a thorough cleaning of the fuel system. During this type of tune-up, we use a three-step process to get rid of harmful varnish, dirt, and carbon deposit buildup in your Cougar’s fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Keep in mind that your Cougar's mileage and maintenance history can uniquely impact its tune-up 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.

Where Should I Go for My Mercury Cougar Tune-Up?

If you’re looking for 1985 Cougar engine tune-up services, head to Firestone Complete Auto Care. Follow Mercury's recommended maintenance schedule or book an appointment as soon as you notice one of the following: shaking while the engine is idling, poor fuel economy, an illuminated check engine light on your dashboard, or a knocking sound when the engine is running.

*Ask a Firestone Complete Auto Care teammate about full terms and conditions for warranties.
