What happens if my Cadillac Seville 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 Cadillac’s recommendations.

What does a puddle underneath my Cadillac Seville mean?

Don't ignore puddles of fluid under your Cadillac Seville. 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.

Are some driving habits better for my Cadillac Seville engine than others?

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.

How often should I clean my Cadillac Seville fuel injectors?

The frequency at which car fuel injectors should be cleaned can vary depending on several factors, including the type of fuel used and the driving conditions. Some manufacturers generally recommend a fuel system cleaning as part of your general car maintenance, or as needed based on symptoms of poor fuel system performance.

Tune Into Your Cadillac Seville

Is your engine overdue for a tune-up? If you usually wait until your car has an issue to take it in for service, it might be time to change your ways, especially if you drive a 1986 Cadillac Seville. Regular engine tune-ups can optimize your Seville’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 get routine engine tune-ups based on Cadillac's recommendations, you invest in your Seville's long-term health and engine performance.

Engine Tune-Up for Cadillac Seville

The Firestone Complete Auto Care location in your community offers several Cadillac Seville engine tune-up services. The first is the standard Firestone Tune-Up. It includes a complete visual inspection of engine components, installation of new spark plugs, and a lifetime warranty on parts*. Another service option pays special attention to the filters in your Seville. Specifically, we replace the fuel filter and air filter. 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 Seville. The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your Seville can determine what kind of service it needs. A one-size-fits-all engine tune-up procedure doesn’t necessarily exist. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

Where Should I Go for My Cadillac Seville Tune-Up?

Schedule your next 1986 Seville engine tune-up service at Firestone Complete Auto Care. Consult your vehicle’s recommended service schedule from Cadillac, or make a service appointment if you notice any of these symptoms from your engine: decreased gas mileage, "rough" idling or stalling when stopped, engine knocking, or an illuminated check engine light.
