What happens if my Mitsubishi Montero spark plugs fail?

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 do I do if I see a pool of liquid under my Mitsubishi Montero?

Don't ignore puddles of fluid under your Mitsubishi Montero. 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 Montero 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-Ups to Help Your Mitsubishi Montero Run Better

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 could be time for a new way of doing things, especially if you want your 1989 Mitsubishi Montero’s engine to last for a long time. Routine engine tune-ups can bring power back to your Montero. They're designed to help your engine start easier and run more efficiently, which can lead to lower emission levels and better fuel economy. When you take your car for regular engine tune-ups as recommended by Mitsubishi, you’re taking vital steps toward keeping your Montero’s engine running smoother, longer.

Engine Tune-Up for Mitsubishi Montero

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1989 Mitsubishi Montero. One option 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 Montero. 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 Montero's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your Montero: your vehicle’s maintenance record and mileage can determine which service is best. 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.
