Choosing 1990 Toyota 4Runner Tires

Beyond the correct tire size, you also want to consider a handful of other factors when buying new Toyota 4Runner tires like which tire brands you like most and where you drive. 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 for summer and one for winter. 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!

Driving style is next on the list to think about when buying tires. 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 Toyota 4Runner tires online.

  • Why does my Toyota engine sound different?  Strange under-the-hood noises can point to problems within your Toyota 4Runner engine. Tapping or knocking could mean you need an oil change.

Answers to Your Toyota 4Runner Car Battery Questions

  • Why won't my Toyota 4Runner battery stay charged?  A car battery that needs to be jump-started every time is as good as dead. It may be getting old. Or, you’ve been leaving the doors slightly open and the dome lights on during the night. Stop in for a free battery check at your nearest Firestone Complete Auto Care and learn more about your battery's charge.
  • 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.
  • What is the white, crusty substance accumulating on my 4Runner’s battery post?  If you notice white, crusty stuff around the battery terminals of your 4Runner, 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 4Runner’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

Oil Changes for 1990 Toyota 4Runner

Your 1990 4Runner’s oil should be changed according to Toyota’s recommended oil change intervals. No matter the mileage, your 4Runner may need its oil changed ASAP if your check engine light is on, you hear knocking sounds coming from the engine, smell oil inside the car, or see an excess amount of vehicle exhaust. You may also need an oil change more frequently than Toyota recommends if you haul heavy loads, frequent dusty roads, go off-roading a lot, or go at low speeds on long distance trips.

Your local Firestone Complete Auto Care has the right 1990 Toyota 4Runner motor oil: either synthetic or conventional. Check your owner's manual and talk with a technician to select the right Toyota 4Runner 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, an auto technician will change your 4Runner’s oil, replace and recycle your used oil and oil filter, inspect the rest of your car’s filters, refill vital car fluids, and perform a free inspection on the rest of your vehicle. Let the experts take care of your 4Runner’s engine by making an oil change appointment today.

1990 Toyota 4Runner Oil Change Questions

  • What can cause the oil light on my Toyota 4Runner to illuminate?  The oil change light in your Toyota 4Runner 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.
  • How hard is it to change Toyota 4Runner 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 Toyota 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.

1990 Toyota 4Runner Engine Tune-Ups & Maintenance

A second service option replaces the air and fuel filter in your 4Runner. Yet another service is a fuel system cleaning process, which involves removing varnish, dirt, and carbon deposits that have built up inside the fuel injectors, throttle body, and throttle plate in your 4Runner. This goes a long way in boosting your fuel system’s overall performance. Here’s something to remember when choosing services: the mileage and service history of your 4Runner can determine what kind of service it needs. Chat with a Firestone technician before you jump into a specific service to ensure your engine tune-up money is well-spent.

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

Common Engine Tune-Up Q&A for 1990 Toyota 4Runner

  • When should Toyota 4Runner spark plugs be replaced?  Replace spark plugs on time or about every 30,000 miles or so. Without the spark of electricity created by spark plugs, your engine doesn’t have the combustion it needs to start — which could leave you stranded on the road. Always replace your spark plugs on time based on Toyota’s recommendations.
  • What should I do if I see leaks under my 4Runner? 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 Toyota 4Runner need to be cleaned? The frequency at which car fuel injectors should be cleaned can vary depending on several factors, including the type of fuel used and the driving conditions. Some manufacturers generally recommend a fuel system cleaning as part of your general car maintenance, or as needed based on symptoms of poor fuel system performance.

1990 Toyota 4Runner Suspension Service & Repair

During the first few years you had your 1990 Toyota 4Runner, the ride was probably so smooth that you didn’t even think about it! But these days, things are starting to feel a bit rough. Maybe your 4Runner jolts, 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 1990 Toyota 4Runner in for suspension and steering service. We'll get to the root of the problem and, if your 4Runner suspension system needs repair, we’ll go over the services you need and how much they will cost before we do any work.

1990 4Runner Steering & Suspension Q&A

  • Why is my Toyota 4Runner bouncing excessively?  If your shocks or struts are in bad shape, they can’t dampen road bumps like they should. This can cause your 4Runner to bounce more than usual.
  • Why does my 4Runner 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 4Runner'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.

A/C Service for Your 1990 Toyota 4Runner

Our trained technicians will do what they can to solve your 1990 Toyota 4Runner A/C problems. During an A/C performance check, we'll determine the condition of your 1990 Toyota 4Runner A/C system to evaluate what repairs are necessary (if any). This check includes a visual inspection, performance test, and pressure and leak test.

Let's say we repair your 1990 Toyota 4Runner A/C system. We will also perform an A/C evacuation and recharge. To start this process, a technician will flush out the old refrigerant from your vehicle’s A/C system. Then, they’ll use Toyota’s specifications to evacuate the system. Finally, we’ll recharge the A/C system with new refrigerant.

Frequently Asked Questions for 1990 Toyota 4Runner A/C Systems

  • Why is my 4Runner A/C blowing hot air? 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 4Runner’s A/C system — and lets outside moisture get in, which can take a toll on internal A/C components.
  • Why won’t my 4Runner’s A/C cool the vehicle when the car is stopped?  Damaged or worn components in your 4Runner’s electrical or air conditioning system can cause the A/C to only work when the car is moving. You may be dealing with low coolant or a faulty cooling fan.

1990 Toyota 4Runner Transmission Service & Repairs

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, a tiny transmission issue can take a major toll on your car’s performance. 1990 Toyota 4Runner transmission issues could include 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 don’t pay attention to Toyota 4Runner transmission trouble you might notice your fuel economy decrease or find that you can't drive your 4Runner at all. Our technicians are trained to service 1990  Toyota 4Runner transmission systems according to vehicle manufacturer recommendations. If you think there’s something wrong with your 4Runner’s transmission, schedule an appointment at your local Firestone Complete Auto Care to help keep your Toyota running for miles and miles.

1990 Toyota 4Runner Transmission Questions & Answers

  • Does my 4Runner's transmission fluid need to be inspected?  Maintaining your Toyota 4Runner transmission fluid is one of the best ways to maintain your transmission's health. A general rule of thumb is to have your transmission fluid checked and changed about every 30,000 to 60,000 miles, but that timeline can change if you're hard on your Toyota. Leaks or low transmission fluid are easy to spot and affordable to repair.
  • Can transmission fluid leak from my Toyota 4Runner?  Over time, transmission fluid can leak from your Toyota 4Runner, 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.
  • Can I drive my Toyota 4Runner with a transmission fluid leak?  Driving your 4Runner with a transmission fluid leak is highly discouraged. Transmission fluid is vital to the smooth operation of your transmission system, and a leak can put the entire system at risk. A transmission fluid leak may lead to decreased performance, overheating, and possibly even transmission failure.
