Your Guide to 1986 GMC S15 Scheduled Maintenance

Take care of your GMC S15 and it'll take care of you. With proactive maintenance, your S15 could be on the road well past the 200,000 mile mark. So, you want to care for your car, but you’re not sure when to get certain services. There's no need to guess when it's time to get S15 maintenance, and no need to wait until something goes wrong. Just follow your 1986 GMC S15 maintenance schedule!

This recommended maintenance schedule is written by the auto manufacturer, GMC themselves. Scheduled maintenance services can vary depending on driving conditions, climate, and other factors; however, there’s a good chance that your vehicle’s recommended maintenance services will include oil changes, tire rotations, brake pad replacement, filter changes, and fluid checks and exchanges. Scheduling routine service appointments is one of the best ways to help extend your S15's life, keep you safer on the road, and prevent common 1986 GMC S15 problems.

Essential Maintenance to Keep Your GMC S15 Running Newer, Longer

Come to Firestone Complete Auto Care for manufacturer-recommended routine maintenance on your 1986 GMC S15 and our technicians will jump right in with a Courtesy Check. A Courtesy Check helps "set the stage" for your service and catch any small problems before they turn into big repairs. Every Courtesy Check will include a visual inspection of your S15. We’ll check your head and tail lights, fluid levels, filters, tires (and their alignment!), and windshield wiper blades. We’ll also perform a free battery check to determine your battery’s charge level.

Think you could be due for a new battery in your 1986 GMC S15? If your current battery is more than three years old, it may be time for a replacement (batteries typically last somewhere between three and five years). Yours may need to be replaced sooner depending on your driving habits and climate. Taking short trips or exposing your car to extreme temperatures (like in the dead of winter or heat of summer) could reduce the life expectancy of your GMC S15 battery. Sure, you could wait until your battery is completely dead, but it’s a much wiser decision to replace it before you need to. If you keep driving on a battery that can't hold a charge, you run the risk of being stranded when your battery finally gives out (and no one can predict where that might be!). Your GMC S15 won't be going anywhere without a strong battery.

Staying on schedule for battery replacements and motor oil changes can support your engine’s overall performance and keep your 1986 GMC S15 running newer, longer. See GMC's recommendations for oil change intervals for your 1986 S15 in the chart at the top of this page. Don’t forget, though, that weather conditions in your area or your personal driving habits can affect this interval. Talk to a Firestone Complete Auto Care technician to know when to change your oil. We can also answer any questions you have about what type of oil to use for your 1986 GMC S15.

Periodic service to the steering system in your GMC S15 can help you keep control of your vehicle at all times (plus, it can make for a smoother ride!). That's important if you plan on taking the road less traveled! Trust our technicians to inspect system components and if needed, perform GMC S15 suspension and steering services. These might include wheel alignment, power steering fluid flushes and replenishments, ball joint lubrication, wheel bearing replacement, and strut replacement. Prevent damage or premature wear and tear on your GMC S15's steering system with regular maintenance.

If you skip recommended GMC S15 services, you (and your engine) could quickly lose your cool when there's a problem on the road–especially if that problem is an overheated engine or broken A/C. Don’t sweat it, though! Our technicians can take care of those issues, too. At Firestone Complete Auto Care, we have what it takes to provide top-notch service for your GMC S15 engine heating and cooling systems, as well as your air conditioning. Is your GMC S15 radiator in need of replacement? We’ve got your back. A/C smelling musty? We’re here to fix that, too. Firestone Complete Auto Care is your one-stop shop for 1986 GMC S15 maintenance and repairs.

We can help you keep your vehicle (and your life!) running smoothly. Many of our locations have weekend and evening hours for your convenience.

Take an active role in maintaining your 1986 GMC S15. Get answers to common GMC S15 maintenance questions and learn more about caring for your vehicle.

  • When should I have GMC S15 alignment checked? Check your car for pothole damage! If you’ve recently hit a pothole (or even if you don’t remember hitting one… they can be sneaky!) check your tire treads, tire sidewalls, and wheels for damage. Potholes can also knock your car out of alignment, so have your alignment checked if you suspect you’ve driven over a rough patch of road lately.
  • When should I use high mileage oil in my GMC S15? Do you have more than 75,000 miles on your GMC S15? If so, request to switch to high mileage oil at your next oil change. This type of oil is specially formulated to keep aging engine parts in the best possible condition.
  • Can GMC dashboard warning lights wait? Because there might be a problem under the hood. Those warning lights are there for a reason! As soon as you notice that one’s illuminated, take your GMC S15 to Firestone Complete Auto Care so you can address any small problems long before they worsen.
