1990 BMW 525i Engine Tune-Ups & Maintenance

Tune-Ups to Help Your BMW 525i 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 might be time to change your ways, particularly if you want to keep your 1990 BMW 525i in tip-top shape. Regular engine tune-ups can optimize your 525i’s power on the road. 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 get routine engine tune-ups based on BMW's recommendations, you’re taking vital steps toward keeping your 525i’s engine running smoother, longer.

BMW 525i Engine Tune-Up Services

Your nearest Firestone Complete Auto Care location has several options to choose from when it comes to BMW 525i engine tune-up services. 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 525i. 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 525i’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 525i can determine what kind of service it needs. This means that a tune-up service that’s a great fit for another car may not be optimal for yours. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

Questions About 1990 BMW 525i Engine Tune-Ups

  • When should BMW 525i spark plugs be replaced? When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.
  • What does a puddle underneath my BMW 525i mean? Don't ignore puddles of fluid under your BMW 525i. 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 525i 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.
