Your Guide to 2021 GMC Sierra 1500 Scheduled Maintenance
Take care of your GMC Sierra 1500 and it'll take care of you. With the right maintenance at the right time, your Sierra 1500 could be on the road well past the 200,000 mile mark. But how do you know what service to get and when? It can be overwhelming, but fortunately, there’s a resource that takes the guesswork out of routine Sierra 1500 maintenance. It’s as easy as following the recommended maintenance schedule that’s been written specifically for your 2021 GMC Sierra 1500!
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; in most cases, though, recommended maintenance will consist of services like oil changes, tire rotations, brake pad replacement, filter changes, and fluid checks and exchanges. Staying on track with routine service appointments can help your Sierra 1500 perform better, keep you safer on the road, and prevent common 2021 GMC Sierra 1500 problems.
Overview of Essential GMC Sierra 1500 Maintenance Needs
Bring your 2021 GMC Sierra 1500 to Firestone Complete Auto Care for factory-recommended maintenance services and our technicians will jump right in with a Courtesy Check. The Courtesy Check helps us see what we’re working with under the hood, and allows us to alert you to any potential problems before they worsen. During a Courtesy Check, we’ll always check your battery, then we’ll move on to inspect your Sierra 1500’s head and tail lights, tires, fluid levels, alignment, and windshield wipers.
Could your 2021 GMC Sierra 1500 be ready for a new battery? 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. Extremely hot or cold temperatures can take a toll on your GMC Sierra 1500 battery, and so can frequent short drives. While you could wait until your battery fails and you hear the dreaded "click," you're better off replacing it before then! Otherwise, you may find yourself (and your trusty Sierra 1500) stuck in the middle of nowhere. Your GMC Sierra 1500 won't be going anywhere without a strong battery.
Ensuring you always have a well-charged battery can help your car’s overall performance, and regularly scheduled oil changes can help your 2021 GMC Sierra 1500's engine run smoother. To learn how often GMC recommends you have the oil changed in your 2021 Sierra 1500, check out the information table at the beginning of this page. Keep in mind that your oil change interval could be different given your driving style and climate. Come in and speak with a Firestone Complete Auto Care technician to find out how often to change your oil. We'll also help you understand what type of oil to use for your 2021 GMC Sierra 1500.
Maintaining your GMC Sierra 1500 steering and suspension system can improve ride comfort and help you maintain control of your vehicle. When it comes to steering and suspension, you want to catch small problems before they turn into big (and expensive) ones. Bring your car to Firestone Complete Auto Care, where our technicians can check your car’s steering components and, if necessary, perform GMC Sierra 1500 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 Sierra 1500's steering system with regular maintenance.
Without routine GMC Sierra 1500 maintenance, 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 Sierra 1500 engine heating and cooling systems, as well as your air conditioning. Need a new GMC Sierra 1500 radiator? We got it. Is your A/C blowing hot air? We’re on it. Firestone Complete Auto Care is the place to go for 2021 GMC Sierra 1500 maintenance.
