Maintenance for Your 2015 GMC Sierra 3500 HD
How often should I service my 2015 GMC Sierra 3500 HD?
Here’s Why 2015 GMC Sierra 3500 HD Scheduled Maintenance Matters
Take care of your GMC Sierra 3500 HD and it'll take care of you. With the right maintenance at the right time, your Sierra 3500 HD 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. It can be overwhelming, but fortunately, there’s a resource that takes the guesswork out of routine Sierra 3500 HD maintenance. Just follow your 2015 GMC Sierra 3500 HD maintenance schedule!
The recommended maintenance schedule is put together by GMC, your vehicle manufacturer. Depending on driving conditions and climate in your area (as well as other contributing factors, like your personal travel habits), your car’s scheduled maintenance needs may vary; in most cases, though, recommended maintenance will consist of services like tire rotations, vital fluid checks/exchanges, filter changes, brake pad replacement, and oil changes. Staying on track with routine service appointments can help your Sierra 3500 HD perform better, increase your vehicle safety, and help you avoid expensive repairs caused by 2015 GMC Sierra 3500 HD problems later.
Overview of Essential GMC Sierra 3500 HD Maintenance Needs
Bring your 2015 GMC Sierra 3500 HD to Firestone Complete Auto Care for factory-recommended maintenance services and an expert technician will begin by performing a Courtesy Check. This Courtesy Check can establish a baseline of what may need to be addressed during your service appointment. Each Courtesy Check includes a free battery test and an inspection of your Sierra 3500 HD's windshield wiper blades, head and tail lights, filters, fluid levels, tires, and alignment.
Think you could be due for a new battery in your 2015 GMC Sierra 3500 HD? 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). Depending on the climate where you live and your habits while driving, your Sierra 3500 HD may need a replacement battery sooner. 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 Sierra 3500 HD battery. It can be tempting to try and get as much life out of your battery as possible, but it’s smart to check it regularly and replace it before it gets too weak. Otherwise, your battery could die unexpectedly, leaving you and your Sierra 3500 HD stranded. Your GMC Sierra 3500 HD won’t even be able to start with a weak battery, much less get you where you need to go.
In addition to maintaining a strong battery, investing in regular oil changes can support your engine’s overall performance and keep your 2015 GMC Sierra 3500 HD running newer, longer. See GMC's recommendations for oil change intervals for your 2015 Sierra 3500 HD 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.
