1989 Nissan D21 Tune-Up & Engine Service

Tune Into Your Nissan D21

Is it tune-up time? 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, particularly if you want to keep your 1989 Nissan D21 in tip-top shape. Periodic tune-ups can bring more power back to your D21’s engine. Tune-ups give your engine a boost in efficiency, so you can enjoy improved fuel economy and lower emissions. When you take your car for regular engine tune-ups as recommended by Nissan, you can rest assured you’re investing in your D21’s long-term engine performance.

Engine Tune-Up for Nissan D21

Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1989 Nissan D21. 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 D21. 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 D21’s fuel injectors, throttle body, and throttle plate. The result? Restored fuel system performance. Here’s something to remember when choosing services: the mileage and service history of your D21 can determine what kind of service it 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.

1989 Nissan D21 Engine Tune-Up Q&A

  • When should Nissan D21 spark plugs be replaced? 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 Nissan’s recommendations.
  • What should I do if I see leaks under my D21? Don't ignore puddles of fluid under your Nissan D21. 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 D21 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.
