What happens if my Isuzu Trooper 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 Isuzu’s recommendations.

What do I do if I see a pool of liquid under my Isuzu Trooper?

Don't ignore puddles of fluid under your Isuzu Trooper. 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 hard starts and stops bad for my Isuzu Trooper engine?

Hard stops and starts can lead to premature wear on your engine’s components. Lighten up that lead foot and opt for steady, fluid starts and stops instead. Your engine (and your passengers!) will thank you.

Tune-Ups to Help Your Isuzu Trooper Run Better

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 1990 Isuzu Trooper’s engine to last for a long time. Periodic tune-ups can bring more power back to your Trooper’s engine. Tune-ups help your engine start smoothly and run efficiently, so you can enjoy improved fuel economy and lower emissions. When you follow the guidelines specified by Isuzu for your vehicle’s tune-up schedule, you can rest assured you’re investing in your Trooper’s long-term engine performance.

Isuzu Trooper Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to Isuzu Trooper engine tune-up services. The standard Firestone Tune-Up is one service option. 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 Trooper. 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 Trooper'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 Trooper: 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! Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.
