Choosing 1989 Nissan D21 Tires

Apart from finding the right tire size, you also want to think about a couple of other things when getting new Nissan D21 tires like which tire brands you like most and where you drive. 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. Drivers in states that fully experience all four seasons often buy two sets of tires: one set for winter, one set for summer. Other drivers buy one set of all-season tires instead. That way they don't have to return to the tire shop and their vehicle is always ready for sun, rain, and light snow!

Your personal driving style is the next factor to consider. If you're an avid off-roader who yearns to pioneer new paths, you have very different tire needs than a highway commuter who doesn't hit the hills very often. 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.

1989 Nissan D21 Tire Questions

  • Is Nissan tire inflation important? The right tire pressure can make all the difference. Proper tire inflation helps increase fuel economy, improve braking time, and boost tire lifespan! Even a small change in tire pressure can impact your driving.
  • Why are there numbers on the side of my Nissan D21 tires? The numbers on your tire sidewall give you information about tire speed rating, traction, treadwear, tire size, and load carrying capacity. Chat with a tire technician to learn how to read the numbers on your Nissan tires!
  • Is there an easy way to check Nissan tire tread depth? 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.

  • How long can I expect my D21 brake pads to last? You can usually get around 30,000 to 40,000 miles out of your brake pads, but how and where you drive your D21 can affect this. Hauling large loads or riding your brakes can shorten their lifespan, while smoothly braking and mostly sticking to highways can help your brake pads last longer.
  • Is it bad if my D21 is leaking brake fluid when off? Your D21 brake system is a closed hydraulic system, so a brake fluid leak likely means you have an issue in your brake system. Over time, brake components can wear out or get damaged, causing a brake fluid leak.

These could all be signs of drivetrain damage you don't want to ignore. Take action quickly to catch repairs or replacements before something more severe happens.
  • What causes a D21’s malfunction indicator light (MIL) to illuminate? Engine problems, transmission problems, faulty sensors, electrical issues, misfire issues, and connector problems could all cause your D21’s malfunction warning light, or better known as the check engine light, to illuminate.
  • How concerning is a drivetrain malfunction in my D21? Don't ignore a drivetrain malfunction in your D21. As soon as you notice a problem, have it checked by a professional mechanic to diagnose the issue and carry out any necessary repairs.

1989 Nissan D21 Alignment Services

An alignment involves making adjustments to your Nissan D21's suspension system, which serves to attach your wheels to your vehicle. During the service, calculated changes are made to the angles of your tires. This is so that your tires hit the road at an optimal angle for your vehicle’s performance — just as Nissan intended. When you bring in your 1989 Nissan D21, we’ll perform an alignment check first. After that, we can adjust your wheel alignment angles until they match Nissan’s recommended measurements.

Questions About Nissan D21 Alignment

  • What can knock my Nissan D21 out of alignment? Hitting a pothole or curb can alter your wheel alignment. So can general wear and tear over time.
  • How often does your D21 need a wheel alignment?  Check your D21 owner's manual for Nissan's recommended interval. It's generally a good idea to check your alignment every 6,000 miles or 6 months, depending on which comes first.
  • Do you need to get your D21 wheels aligned when you get new tires? It’s likely not a requirement to get an alignment when you install new tires on your D21, but it's a smart idea to do so anyway. An alignment can help ensure even tire wear, smooth handling, and better fuel efficiency.

1989 Nissan D21 Engine Q&A

  • Why does the check engine light in my D21 turn on when I start my car? Generally, your check engine light turning on upon ignition is not a bad thing. It’s just your D21 firing up its circuits. The light should turn off in a bit, but come see us if it doesn't.
  • Why does my Nissan engine sound different? Strange engine sounds can be a sign something’s off in your Nissan D21. Knocking or tapping could be a symptom of low oil. A high-pitched whistle could signal an intake leak or misaligned belt. Squealing can be traced back to a loose fan belt, and grinding might be a sign of brake problems rather than engine issues.
  • What could damage a Nissan engine? Certain driving habits can damage your engine and should be avoided. These habits include 'running on fumes,' revving the engine while still in Park, or pushing 'the pedal to the metal' before the engine has warmed up.

Nissan D21 Tire Repair Questions

  • How soon should I have my flat tire repaired? 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? A temporary sealant may be able to help you get to a repair location safely. But temporary or emergency sealants could possibly damage TPMS sensors, and in some cases may even void the warranty on your Bridgestone or Firestone tires. If your tire needs extensive repair, sealant can add time and labor costs to the process.
  • What is causing the tires on my D21 to keep losing air? Your D21 tires might keep losing air due to a leaking valve stem, puncture or hole in the tire tread or sidewall, or damaged wheel.

Top Nissan D21Car Battery Questions

  • Why doesn’t my Nissan D21 battery stay charged? A battery is in its final hour when it will no longer hold a charge. The battery may be too old. Or, you may have been leaving your car doors ajar and the cabin light at night. Stop by for a complimentary battery check at your favorite Firestone Complete Auto Care and get a handle on your car battery’s health.
  • How long do car batteries last?  A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.
  • Why is there white, crusty buildup on my D21’s battery post?  The white, flaky stuff that can build up around your D21’s battery terminals is known as corrosion. Acid leaking from your vehicle’s battery post can have a chemical reaction with the air, leading to an accumulation of the white, powdery substance over time. Corrosion can affect the flow of electricity between your battery and the electrical system in your D21, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.

Oil Changes for 1989 Nissan D21

Your 1989 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 knock knock knock coming from the engine, sense an oil smell in the cabin, or notice excess vehicle exhaust. You might need an oil change more frequently than what’s recommended by Nissan if you regularly haul heavy loads, drive in dusty areas, enjoy off-roading, or drive at low speeds for long distances.

Whether it’s synthetic, conventional, or a blend of both — your local Firestone Complete Auto Care has the right oil for your Nissan D21. Talk with a teammate and consult your owner's manual before picking a motor oil. At Firestone Complete Auto Care, you can choose from the following oils: Quaker State® Advanced Durability™ conventional oil, Pennzoil® High Mileage Vehicle® motor oil, Pennzoil Platinum® Full Synthetic motor oil with PurePlus™ Technology, and Shell Rotella® heavy-duty engine oil. During an oil change, an auto technician will change your D21’s oil, replace and recycle the old oil and filter, inspect all of your other filters, top-off essential fluids, and visually inspect the rest of the vehicle. Make an appointment for an oil change service today and let the oil experts take care of your D21's engine.

Oil Change Q&A for Your 1989 Nissan D21

  • What does it mean if my Nissan D21 oil light comes on?  Your Nissan D21 oil change reminder light might illuminate if it’s been too long since your last oil change. On the other hand, the oil pressure light might illuminate due to a clogged oil filter, a faulty oil pressure sensor, low engine oil levels, or a malfunctioning oil pump.
  • Can I change my Nissan D21 oil at home?  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 D21 spewing blue or gray exhaust smoke?  Your engine could be burning oil due to a leak.  It may be time for a pro to take a look. A leak can be caused by a variety of issues including faulty valve seals, blown piston rings, or damaged cylinder walls.

1989 Nissan D21 Engine Tune-Ups & Maintenance

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 1989 Nissan D21. One option is the standard Firestone Tune-Up. This includes the installation of new spark plugs and a visual inspection of your engine’s components, plus a lifetime warranty on parts*. The second service focuses on your D21's filters, specifically replacing the air filter and fuel 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 can improve your fuel system’s performance (and therefore, your engine’s performance). Here’s something to remember when choosing services: the mileage and service history of your D21 can determine what kind of service it needs. Talk to a technician about your driving style, mileage, and service history to learn more about your vehicle's specific needs.

*Ask a Firestone Complete Auto Care teammate about full terms and conditions for warranties.

1989 Nissan D21 Engine Tune-Up Q&A

  • Will it hurt my Nissan D21 to drive with old spark plugs?  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? Don't ignore puddles of fluid under your Nissan D21. 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.
  • How often should I clean my Nissan D21 fuel injectors? The cleaning schedule for vehicle fuel injectors varies depending on your driving conditions and the type of fuel you use. Some manufacturers suggest cleaning your fuel system as part of routine maintenance, while others will recommend it on an as-needed basis if you’re experiencing poor performance. Reference your Nissan owner’s manual for exact guidelines.

Suspension Service & Repair for 1989 Nissan D21

When you first bought your 1989 Nissan D21, you probably enjoyed a smooth and steady ride. But these days, things are starting to feel a bit rough. Perhaps your D21 feels bouncy, sways to one side, or makes an unusual noise when going over a speed bump. The first sign of trouble is the best time to bring your 1989 Nissan D21 in for steering and suspension repairs. We'll get to the root of the problem and, if your D21 suspension system needs repair, we'll explain all of your options and the potential cost.

1989 Nissan D21 Steering & Suspension Questions

  • Why is my Nissan D21 bouncing excessively?  If your shocks or struts are in bad shape, they can’t dampen road bumps like they should. This can cause your D21 to bounce more than usual.
  • Why does my D21's nose dive down when I hit the brakes?  When you brake, the forward momentum combined with your vehicle's weight sends a lot of force to the vehicle's front end. A bad suspension can cause all that weight and force to push the front end downward.
  • 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.

Convenient & Local 1989 Nissan D21 A/C Service

Technicians at Firestone Complete Auto Care are ready to help you address your 1989 Nissan D21 A/C problems. During an A/C performance check, we'll determine the condition of your 1989 Nissan D21 A/C system to evaluate what repairs are necessary (if any). This check will include an examination of system pressure, a visual inspection, and a leak test.

While your 1989 Nissan D21’s air conditioner is being serviced, we’ll also do 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). Then, they’ll perform an evacuation (also known as a discharge) on the entire system per Nissan guidelines. Finally, we’ll recharge the A/C system with new refrigerant.

Frequently Asked Questions for 1989 Nissan D21 A/C Systems

  • Why do I get hot air from my D21 A/C? If your car’s air conditioning isn’t blowing cold air at all (or it tries, then turns warm), you could have a clogged expansion valve, a faulty compressor clutch, a leak, or a malfunctioning fuse in the system.
  • What can cause an A/C system leak?  A/C system leaks are often due to a combination of age and moisture. Rubber seals and gaskets naturally degrade over time, allowing refrigerant to exit and moisture to enter your D21's A/C system.
  • Why won’t my D21’s A/C cool the vehicle when the car is stopped? 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.

1989 Nissan D21 Transmission Service

The transmission delivers power from the engine to the wheels so that you can drive on your terms. Because your transmission is responsible for converting the right amount of power into the right amount of speed, a small transmission issue can put a big dent in your D21’s performance. 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. If you don’t pay attention to Nissan D21 transmission trouble you could see your fuel economy decrease or discover that your D21’s not even driveable. Our technicians know how to service your 1989 D21 up to Nissan-recommended standards. As soon as you suspect something’s wrong with your D21’s transmission, book an appointment at your local Firestone Complete Auto Care to help diagnose, treat, and prevent major transmission issues.

1989 Nissan D21 Transmission Q&A

  • 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.
  • Can Nissan D21 transmission fluid leak? 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.
  • Is it okay to drive a D21 with 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.

Vehicle Inspection for 1989 Nissan D21

When you bring your vehicle to Firestone Complete Auto Care for any service, we’ll automatically do a multi-point Courtesy Check. First, a technician will pop the hood on your Nissan D21 and test the battery to determine how much charge remains. We’ll follow the battery inspection with a visual check of your Nissan D21’s filters, lights, wiper blades, fluid levels, belts, hoses, tires, and alignment.

While every visit to your local Firestone Complete Auto Care includes a Courtesy Check, you can also request a Complete Vehicle Inspection for your 1989 Nissan D21 if you suspect there may be a bigger problem. During a Complete Vehicle Inspection, we’ll visually check everything that’s on the list for a Courtesy Check. Additionally, we’ll perform an examination (by hand!) of your steering, suspension, brakes, and exhaust system. This inspection is aimed at informing you of any major problems that could require preventative maintenance.

Depending on where you live, your local Firestone Complete Auto Care may be able to perform state-mandated inspections or safety tests on your vehicle. Specific requirements for these types of inspections vary by state.

1989 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.

1989 Nissan D21 Radiator Q&A

  • Why is the coolant light on my Nissan dashboard on?  Pay attention to the temperature gauge and lights on your dashboard. If a low coolant warning light comes on or your dashboard temperature gauge keeps rising, it’s likely that your engine is about to overheat (and could leave you stranded on the road). Wait for the engine to cool down, then have your coolant system checked immediately at your nearest Firestone Complete Auto Care.
  • What is causing my D21 to overheat?  Low coolant, a damaged cooling fan, a faulty water pump, a malfunctioning thermostat, or a clogged radiator could all cause your Nissan D21 engine to overheat.
  • What can cause a D21 radiator to make boiling or rumbling sounds? If your radiator sounds like it's boiling or rumbling, you could have air pockets in the cooling system of your D21. You might also have a damaged radiator cap (super easy to fix!) or a clogged radiator.
