About 1986 Nissan D21 Tires

Beyond the correct tire size, there are a couple of other factors to consider when buying Nissan D21 tires like where and how you drive, and what tire brand you trust most. Think about where you live (countryside vs. city vs. mountains) and the kind of unexpected weather you're likely to experience when evaluating your driving conditions. It's not uncommon for drivers in states that experience all four seasons to buy more than one set 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!

Your personal driving style is the next factor to consider. If you're a big off-roading fan who forges paths where others can't, you have very different needs than a long-distance commuter who sticks to the highway. Visit your local Firestone Complete Auto Care for help selecting the tire that's right for you, or get started by browsing tires that fit your Nissan D21.

Engine Q&A 1986 Nissan D21

  • Will a temporary sealant fix my Nissan's flat tire? Temporary sealants will solve your problem… for a little bit.

1986 Nissan D21 Maintenance Questions

  • What should I do after hitting a pothole in my Nissan D21?  You know your Nissan D21 better than anyone else, so you’ll know if something doesn’t feel right while driving. Have your alignment checked (and adjusted if necessary) as soon as you notice a pulling steering wheel to prevent suspension damage or uneven tire wear.
  • When does my Nissan D21 need high mileage oil?  If your Nissan D21 has ticked past 75,000 miles, consider switching to high mileage oil at your next oil change to give your engine what it needs to go another 75,000 (or more!). High mileage oil: make it a high priority!
  • Why are my Nissan dashboard lights on?  It's better to get them addressed as soon as possible. An illuminated dashboard light means something in your vehicle isn't functioning like it should.

1986 Nissan D21 Oil Change Service

Nissan recommends changing your 1986 D21’s oil at regular intervals. No matter the mileage, your D21 may need its oil changed ASAP if your check engine light is on, you hear knocking sounds coming from the engine, sense an oil smell in the cabin, or see an excess amount of vehicle exhaust. You might need an oil change more frequently than what’s recommended by Nissan if you regularly haul heavy loads, frequent dusty roads, go off-roading a lot, or go at low speeds on long distance trips.

Whether you need high mileage oil, synthetic oil, or conventional oil, you'll find the right 1986 Nissan D21 motor oil at Firestone Complete Auto Care. 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. During your oil change service, a technician will change your D21's oil, replace and recycle your used oil and oil filter, check all of your other filters, top-off essential fluids, and visually inspect the rest of the vehicle. Let the experts take care of your D21’s engine by making an oil change appointment today.

Oil Change Q&A for Your 1986 Nissan D21

  • Why is my Nissan D21 oil light illuminated?  If you’re overdue for an oil change, it might trigger your Nissan D21 oil change reminder light. If the oil pressure light is illuminated, it could be due to low engine oil, a failing oil pump, a malfunctioning oil pressure sensor, or a clogged oil filter.
  • How hard is it to change Nissan D21 oil at home?  Changing your own oil isn't as convenient as you might think. It requires special tools and old oil must be disposed of properly. Having your oil professionally changed reduces the chances of something going wrong with the oil change, but also with your vehicle down the road.
  • Why is my Nissan D21 exhaust smoke grayish 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.

The result? Restored fuel system performance. Keep in mind that your D21's mileage and maintenance history can uniquely impact its tune-up needs. Ask one of our technicians what your vehicle needs, based on your driving habits and your car’s current condition.

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

Common Engine Tune-Up Q&A for 1986 Nissan D21

  • Will it hurt my Nissan D21 to drive with old spark plugs? When it’s time to replace the spark plugs, don’t delay. These small (but vital!) parts provide the electric spark that your car needs in order to start, and old spark plugs can prevent your car from starting at all. Replace spark plugs on time or about every 30,000 miles or so.
  • What do I do if I see a pool of liquid under my Nissan D21? Puddles could indicate that your vehicle is leaking coolant, oil, or brake fluid. Ignoring these leaks can lead to permanent engine damage, so address these symptoms ASAP with a tune-up service.
  • How often should I clean my Nissan D21 fuel injectors? There is no hard and fast rule on how often fuel injectors should be cleaned, and it can vary based on driving habits and fuel type. Some manufacturers may suggest including a fuel system cleaning in your regular maintenance schedule. Or you may need to clean your fuel injectors as needed if you notice signs of a fuel system problem.

1986 Nissan D21 Suspension Service & Repair

When you first bought your 1986 Nissan D21, you probably enjoyed a smooth and steady ride. But these days, things are starting to feel a bit rough. Maybe your D21 bounces, sways to one side, or makes noise whenever you turn or drive over a speed bump. The first sign of trouble is the best time to bring your 1986 Nissan D21 in for suspension and steering service. We’ll get to the source of your car problems and, if your car needs steering and suspension repairs, we’ll go over the services you need and how much they will cost before we do any work.

Questions About 1986 Nissan D21 Steering & Suspension

  • 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 tilt forward 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 treadwear and tire pressure impact my D21's steering and suspension?  Keeping your tires properly inflated can help reduce strain on the suspension, and also help you notice when you need new tires. A tire that doesn't have an adequate amount of tread can't grip the road or function as well as the manufacturer intended.

Convenient & Local 1986 Nissan D21 A/C Service

Our technicians will work to solve your 1986 Nissan D21 A/C problems to the best of their ability. During this initial A/C performance check, we’ll look at the state of your 1986 Nissan D21’s A/C system to see if repair work is required. We’ll test overall system performance, check for any leaks, and measure the system pressure.

When we perform an A/C repair on your 1986 Nissan D21, we’ll also do an A/C evacuation and recharge. During this process, a technician will remove the old refrigerant from the A/C system. Then, they’ll use Nissan’s specifications to evacuate the system. Finally, we’ll recharge the A/C system with new refrigerant.

Frequently Asked Questions for 1986 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 causes A/C system leaks? 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?  A problem with one or more of your air conditioning or electrical system components could cause the A/C to only work when your D21 is moving. You may be low on refrigerant, or the cooling fan could be faulty.

1986 Nissan D21 Transmission Service

The transmission delivers power from the engine to the wheels so that you can drive on your terms. Since the transmission has to translate the precise amount of power for your desired amount of speed, even the smallest transmission problems should be addressed right away. Nissan D21 transmission problems can present themselves as shifting delays, grinding or jumping during acceleration, the car shaking at any speed, or whistling noises or a burning smell coming from beneath the hood. If you ignore Nissan D21 transmission issues you could see your fuel economy decrease or discover that your D21’s not even driveable. Our technicians are trained to service 1986  Nissan D21 transmission systems according to vehicle manufacturer recommendations. If you think there’s something wrong with your D21’s transmission, schedule an appointment at your local Firestone Complete Auto Care to help keep your Nissan running for miles and miles.

1986 Nissan D21 Transmission Questions & Answers

  • How often does my D21 transmission fluid need to be checked?  Regularly checking and exchanging your 1986 D21’s transmission fluid is one of the best ways to help the transmission system perform. Some technicians would say that between 30,000 and 60,000 miles is a good timeframe for having your Nissan's transmission fluid checked and replaced, but that timeline can vary depending on how your vehicle is used and your manufacturer’s recommendations. The good news is that transmission fluid leaks are affordable to repair and easy to spot.
  • Is it possible for transmission fluid to leak from my Nissan D21?  Over time, transmission fluid can leak from your Nissan D21, potentially causing transmission problems. A transmission fluid leak may be caused by a damaged transmission pan, faulty transmission cooler lines, worn-out seals, a cracked transmission housing, or an overfilled transmission.
  • Is it okay to drive a D21 with a transmission fluid leak?  You should avoid driving with a transmission fluid leak. Your transmission system relies on transmission fluid to operate properly, and a leak may decrease performance, cause your D21 to overheat, or even lead to transmission failure.

1986 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.
  • My D21 overheated! What can cause that?  If your Nissan D21 engine overheats, it could be because of a clogged radiator, a damaged thermostat, a faulty cooling fan, a malfunctioning water pump, or low coolant levels.
  • 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.
