About 1991 Nissan D21 Tires

Apart from finding the right tire size, there are a couple of other factors to consider when buying Nissan D21 tires like how and where you drive, and how much you want to spend. When evaluating your driving conditions, think about where you live (countryside vs. city vs. mountains) and the kind of unexpected weather you're likely to experience. Many drivers who live in states that experience all four seasons choose to purchase two sets of tires: one set for winter, one set for summer. Other drivers prefer the convenience of all-season tires. They make one trip to the tire shop and they're pretty much ready for rain, light snow, or sun!

Next, consider your driving style. If you're a diehard off-roader, you have very different tire needs than a highway commuter who doesn't leave the paved path. Talk to a tire technician at Firestone Complete Auto Care for help choosing the best tire for you, or start shopping for Nissan D21 tires online.

1991 Nissan D21 Tire Questions

  • Why check Nissan tire inflation? A small decrease in tire pressure can have a big impact on your driving. Maintaining proper tire pressure can help improve braking time, increase fuel economy, and boost tire lifespan.
  • Why are there numbers on the side of my Nissan D21 tires? Your tire sidewall numbers tell you the recommended load carrying capacity, speed rating, treadwear, traction, and tire size. Talk to a tire technician to learn how to read Nissan tire numbers.
  • Can I check the tread depth on my Nissan tires at home? Stay on top of your tire tread depth to help avoid a dangerous drive. You can check tread depth with a penny. Hold the penny so that Abraham Lincoln is facing you, then place your penny into a tread groove upside down. If you can see the top of Abe’s head, your tread is shallow and it might be time for new Nissan D21 tires. Grab a penny. Hold the so that Abe Lincon's head is facing you and his hair is pointing toward the ground. Then, place the penny into a tread groove.

For example, mainly driving on highways and gradually braking can help increase the lifespan of your brake pads, and carrying hefty loads or riding your brakes can shorten it.
  • Does brake fluid leak when the car is off? Your D21 brake system is a closed hydraulic system, which means that the brake fluid should not leak out of the system under normal circumstances. However, over time, the various components of the brake system can wear out or become damaged, which can cause brake fluid to leak out of the system.

Answers to Nissan D21 Alignment Questions

  • Are there road conditions that can hurt my Nissan D21 alignment? When it’s safe to do so, avoid driving over potholes or hitting curbs. These road obstacles can wreak havoc on your wheel alignment, as can wear and tear from rough road conditions.
  • How frequently should you get a wheel alignment for your D21? Generally, it’s wise to have your alignment looked at around every 6,000 miles or 6 months, whichever happens first. You should check your D21 owner’s manual to verify Nissan’s suggested interval.
  • Do you need to get your D21 wheels aligned when you get new tires? While you don’t necessarily need to get an alignment when putting new tires on your D21, it’s still a good idea. Ensuring your wheels are properly aligned can help support optimal handling, tire wear, and fuel efficiency.

1991 Nissan D21 Engine Q&A

  • Why does the check engine light in my D21 turn on when I start my car? It’s usually normal for your check engine light to turn on upon ignition. This is just your D21 testing its circuits. The dash light shouldn't stay on. If it does, you might want to bring your vehicle in for service.
  • Why is my Nissan D21 making engine noise? Unusual noises can signal a problem with your Nissan D21 engine. Tapping or knocking could mean you're low on oil. Whistling could mean a belt is misaligned or there's an intake leak. Squealing can indicate a loose fan belt, and grinding might be coming from the brakes, not the engine.
  • What could damage a Nissan engine? Certain driving habits can hurt your engine. These habits include driving on an empty fuel tank, revving your engine while the vehicle is in Park, or slamming the gas pedal while the engine is still cold. Steer clear of these habits to help protect engine performance and efficiency.

Frequently Asked Nissan D21 Tire Repair Questions

  • Can I drive my Nissan on a flat tire? A flat tire that’s not addressed can take a terrible toll on the rest of your car. Until you have it repaired or replaced, drive your D21 as little as possible to reduce your risk of damage to the wheels and alignment – or further damage to that already struggling tire!
  • Can I use an emergency/temporary sealant to fix my Nissan's flat tire? Fast fixes are a mixed blessing. They’ll help you get your Nissan D21 to Firestone Complete Auto Care, but don’t count on them to keep you on the road for very long. Using a temporary sealant may also void a Bridgestone or Firestone tire warranty.
  • Why do the tires on my D21 keep losing air?  If your D21 tires are always losing air, you may have a puncture, damaged wheel, or leaking valve stem.

About 1991 Nissan D21 Scheduled Maintenance

Instead of waiting for an issue to arise with your D21, you can stay ahead of problems before they even begin.

1991 Nissan D21 Maintenance Q&A

  • What do I do if I hit a pothole in my Nissan D21?  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 switch my Nissan D21 to high mileage oil?  Got 75,000+ miles on the odometer? Consider high mileage motor oil. High mileage oil is formulated to address the specific problems encountered by high mileage vehicles, or those with more than 75,000 miles. It can help reduce oil consumption, smoke, and emissions from older Nissan D21 engines.
  • Can Nissan 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 Nissan D21 to Firestone Complete Auto Care so you can address any small problems long before they worsen.

Answers to Your Nissan D21 Car Battery Questions

  • Why doesn’t my Nissan D21 battery stay charged?  A battery that won't hold a charge is almost as good as dead. The battery might be old. Or, you may have a habit of leaving your car doors open and the lights on overnight. Stop by for a free battery test at your local Firestone Complete Auto Care to learn more about the state of your battery.
  • How long can I expect my car battery to last?  Car battery lifespan varies depending on a few factors, including driving conditions, accessories, how well it’s maintained, and the type of battery. On average, a car battery lasts about three to five years.
  • Why is there white, flaky stuff around my D21’s battery post?  If you notice white, crusty stuff around the battery terminals of your D21, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your D21’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

1991 Nissan D21 Oil Change Service

Your 1991 D21’s oil should be changed according to Nissan’s recommended oil change intervals. No matter the mileage, your D21 may need its oil changed ASAP if your check engine light is on, you hear engine knocking, sense an oil smell in the cabin, or notice excess vehicle exhaust. You may also need an oil change more frequently than Nissan recommends if you haul heavy loads, frequent dusty roads, enjoy off-roading, or go long distances at low speeds.

Your local Firestone Complete Auto Care has the right 1991 Nissan D21 motor oil: either synthetic or conventional. Check your owner's manual and talk with a technician to select the right Nissan D21 oil, whether it's Quaker State® Advanced Durability™ conventional oil, Pennzoil® High Mileage Vehicle® motor oil, Pennzoil Platinum® Full Synthetic motor oil with PurePlus™ Technology, or Shell Rotella® heavy-duty engine oil. In an oil change service, a technician will change your D21's oil, replace and recycle your used oil and oil filter, inspect all of your other filters, top-off important fluids, and visually inspect the rest of the vehicle. Get professional engine care by making an oil change appointment for your D21 today.

1991 Nissan D21 Oil Change Questions

  • Why is the oil light on in my Nissan D21?  The oil change light in your Nissan D21 could be triggered by an overdue oil change. However, if the oil pressure light is on, you may be dealing with low engine oil, a failing oil pump, a clogged oil filter, or a malfunctioning oil pressure sensor.
  • Can I change my Nissan oil on my own?  Changing engine oil at home isn’t as simple as it’s made out to be. You’ll have to figure out how to properly dispose of the oil and buy special tools. Having your oil changed professionally can not only reduce the risk of something going wrong during the service, but it’ll also help your car perform smoothly down the road.
  • Why is my Nissan exhaust smoke gray or blue?  There could be an oil leak and your engine is burning oil. Time to have a qualified technician check things out. The leak could be caused by several issues like leaking valve seals, damaged piston rings, or worn cylinder walls.

1991 Nissan D21 Tune-Up & Engine Service

Routine engine tune-ups can bring power back to your D21. Your local Firestone Complete Auto Care offers a range of engine tune-up services for your 1991 Nissan D21. The standard Firestone Tune-Up is one service option. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. Another service option pays special attention to the filters in your D21. Specifically, we replace the fuel filter and air filter. The third tune-up option is a fuel system cleaning service, which is a three-step process that removes varnish, dirt, and carbon deposits on your D21's fuel injectors, throttle body, and throttle plate. This goes a long way in boosting your fuel system’s overall performance. Consider this when choosing a tune-up service for your D21: your vehicle’s maintenance record and mileage can determine which service is best. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

*Check with a teammate at Firestone Complete Auto Care for complete terms and conditions regarding warranties.

1991 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. Spark plugs are small but mighty. The spark of electricity that the plug emits across a small gap creates the ignition for the combustion needed to start your car. Without that spark, your car won't start.
  • What should I do if I see leaks under my D21? Puddles could indicate an oil leak, coolant leak, or brake fluid leak– all of which can critically hurt your engine. Have your engine inspected as soon as you spot a pool of liquid in your usual parking spot.
  • How frequently do the fuel injectors in my Nissan D21 need to be cleaned? Factors like fuel type and driving conditions can affect how frequently you need to clean your D21 fuel injectors. Some manufacturers recommend a fuel system cleaning as part of routine maintenance, or as needed if your vehicle is showing signs of poor fuel system performance.

Suspension Service & Repair for 1991 Nissan D21

During the first few years you had your 1991 Nissan D21, you and your passengers probably enjoyed a ride that was smooth and balanced. Now, however, things are starting to feel a little rough. Maybe your D21 jolts, pulls to one side, or makes a weird sound when you drive over a speed bump or turn. As soon as you notice that something’s “off” with your 1991 Nissan D21, bring it in for suspension and steering service. We'll get to the root of the problem and, if steering and suspension service is needed, we’ll explain what your car needs and how much it’ll cost to get it done. We won't begin any work without your permission.

1991 Nissan D21 Steering & Suspension Questions

  • Why does my Nissan D21 bounce so much?  Excessive bouncing in your Nissan D21 might be due to damaged struts or shocks that are unable to absorb road bumps effectively, causing your vehicle to feel more like a pogo stick than a smooth ride.
  • Why does my D21's nose dive down when I hit the brakes?  The forward momentum and weight transfer to the front wheels during braking can cause your D21's front end to dip forward. A damaged or faulty suspension system may fail to distribute the weight and force effectively, causing the front end to dip even more.
  • Does tire pressure and tread depth impact my Nissan's suspension?  Maintaining your tires can help reduce strain on the suspension, nd also let you know when it's time to replace your tires. A faltering steering and suspension system could lead to uneven tire wear.

A/C Service for Your 1991 Nissan D21

Technicians at Firestone Complete Auto Care are ready to help you address your 1991 Nissan D21 A/C problems. In this A/C performance inspection, we’ll check out the current condition of your 1991 Nissan D21 A/C system to evaluate what repairs are necessary (if any). We’ll test overall system performance, check for any leaks, and measure the system pressure.

Let's say we repair your 1991 Nissan D21 A/C system. We will also perform an A/C evacuation and recharge. To do this, one of our technicians will remove the refrigerant in your A/C system (if there is even any left to remove). Next, they will evacuate the system according to Nissan's recommendations. The A/C system is recharged with new refrigerant.

Frequently Asked Questions for 1991 Nissan D21 A/C Systems

  • What’s making my D21 A/C put out warm air? Maybe your A/C starts cool but then gets warm. Or maybe it never gets cold in the first place. Either way, your A/C troubles could be traced back to a clogged expansion valve, faulty compressor clutch, blown fuse, or leak.
  • How does my A/C system get a leak? To put it simply, age and moisture are some of the main causes of leaks in your A/C. Over time, rubber gaskets and seals can wear out, which pushes much-needed refrigerant out of your D21’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
  • Why does my vehicle have to be moving for my D21’s A/C to work? There could be issues with one or more components in the air conditioning or electrical system. Your D21 may have a faulty cooling fan or low refrigerant.

Transmission Services for 1991 Nissan D21

The transmission delivers power from the motor to your wheels so that you can drive at your desired speed. Because your transmission is responsible for converting the right amount of power into the right amount of speed, even the smallest transmission problems should be addressed right away. Nissan D21 transmission problems can present themselves as shifting delays, grinding when accelerating, a feeling of shakiness, or a burning smell or whistling sounds coming from under the hood. Let Nissan D21 transmission problems linger and you could see your fuel economy decrease or discover that your D21’s not even driveable. Our technicians are trained to service 1991  Nissan D21 transmission systems according to vehicle manufacturer recommendations. Schedule an appointment at your local Firestone Complete Auto Care at the first sign of transmission problems to help diagnose, treat, and prevent major transmission issues.

Questions About 1991 Nissan D21’s Transmission

  • Does my D21's transmission fluid need to be inspected?  Caring for your Nissan D21’s transmission fluid is a great way to help it perform. About every 30,000 to 60,000 miles is a good timeframe for having your transmission fluid inspected and perhaps changed. Service intervals can vary depending on how you use your Nissan, so check with your technician first. Luckily, leaks and low fluid levels are easy to spot and inexpensive to fix.
  • Is it possible for transmission fluid to leak from my Nissan D21? Yes, your Nissan D21 can develop a transmission fluid leak. As your D21 ages, parts of the transmission system might wear out or break down, leading to a leak and possible transmission issues. Common causes of transmission fluid leaks include worn seals, a damaged transmission housing, a loose or cracked transmission pan, an overfilled transmission, or faulty transmission lines.
  • Can I still drive my Nissan D21 if it has a transmission fluid leak?  It’s not advisable to drive your D21 if it’s leaking transmission fluid. Your transmission system needs transmission fluid to function properly, and a leak can lead to significant problems, such as overheating or reduced performance. You might even experience transmission failure.

1991 Nissan D21 Inspections

At Firestone Complete Auto Care, we perform a multi-point Courtesy Check during any vehicle service. To start, one of our technicians will check the battery in your Nissan D21 to find out how much charge is remaining on it.

1991 Nissan D21 Vehicle Inspection Q and A

  • How do I know if I should have an inspection on my Nissan D21? You drive your car, day in and day out, so you know it best. If you notice unusual engine noises or you can’t shake the feeling that something is 'off,' start with a Courtesy Check to stay ahead of potential issues.

  • When should I get a complete vehicle inspection for my Nissan D21?  The best time to have a complete vehicle inspection done on your Nissan D21 is when you notice something is off but you can’t locate the issue yourself. Schedule an inspection if you experience any unusual symptoms, such as unfamiliar dashboard indicators, strange engine noises, or steering changes. An inspection can be especially beneficial before a road trip for the simple peace of mind. You can feel confident in your adventure!

1991 Nissan D21 Radiator Repair & Service

Keeping up with regular radiator maintenance in your 1991 Nissan D21 is crucial to keep your engine in the best possible shape for years to come. Nissan recommends that you replace coolant (also called antifreeze) at certain intervals, but it’s also wise to keep an eye out for signs of a failing radiator. You could be on the verge of a radiator-induced engine breakdown if you notice leaking coolant, overheating, or an illuminated low coolant dashboard light.
