Parts For 2014 Nissan Altima

The 2014 Nissan Altima, a mid-size sedan known for its fuel efficiency and comfortable ride, remains a popular choice on the used car market. Whether you're a seasoned mechanic maintaining a fleet or a dedicated owner looking to keep your Altima running smoothly, knowing the right parts and where to find them is crucial. This guide dives into the essential components for the 2014 Altima, covering everything from routine maintenance to potential upgrades.

Engine Components and Maintenance

The 2014 Altima primarily came with two engine options: a 2.5-liter QR25DE inline-4 and a 3.5-liter VQ35DE V6. Both engines are generally reliable but require regular maintenance to ensure optimal performance.

QR25DE (2.5-liter Inline-4) Parts

This engine is the more common of the two and is known for its fuel efficiency. Key maintenance parts include:

Oil Filters: Essential for maintaining engine cleanliness. Use a quality filter, such as a Nissan OEM filter (15208-9F60A) or a reputable aftermarket brand like Mobil 1 or Bosch.
Air Filters: Replacing the air filter regularly ensures proper airflow to the engine. Check and replace every 12,000-15,000 miles, or sooner if driving in dusty conditions.
Spark Plugs: The QR25DE typically uses iridium spark plugs, offering long life and reliable ignition. NGK or Denso iridium plugs are recommended. Replace around 100,000 miles.
Drive Belts: Inspect the drive belt (or serpentine belt) for cracks or wear. Replace as needed to avoid loss of power steering, alternator function, or air conditioning.
Coolant: Use Nissan Genuine Coolant or a compatible coolant designed for Asian vehicles. This helps prevent corrosion and ensures proper cooling system function. Flush and replace every 30,000 miles.
Engine Mounts: Worn engine mounts can cause vibrations and noise. Inspect and replace as needed to maintain a smooth ride.

Real-world Example: A customer complained of a rough idle and decreased fuel economy in their 2014 Altima with the QR25DE engine. After replacing the spark plugs and air filter, the issue was resolved, restoring smooth operation and improved MPG.

VQ35DE (3.5-liter V6) Parts

The VQ35DE offers more power and a smoother driving experience. While similar to the QR25DE in terms of basic maintenance, there are some key differences:

Oil Filters: Similar recommendations to the QR25DE, use quality filters like Nissan OEM (15208-9F60A) or Mobil 1/Bosch.
Spark Plugs: Iridium spark plugs are also used in the VQ35DE. NGK or Denso are good choices.
Timing Chain: The VQ35DE uses a timing chain, which generally lasts longer than a timing belt. However, listen for any unusual noises (rattling) that could indicate chain wear or tensioner issues.
Ignition Coils: The V6 has six ignition coils, one for each cylinder. If you experience misfires, you may need to replace one or more coils. Use quality replacements from Hitachi or Denso.

"Using the correct oil type and viscosity is critical for both engines. Consult your owner's manual for the manufacturer's recommendations. Generally, a synthetic 5W-30 oil is a good choice for both the QR25DE and VQ35DE."

Transmission Components

The 2014 Altima uses a continuously variable transmission (CVT). CVTs are known for their fuel efficiency, but they also require specific maintenance.

CVT Fluid: This is the most critical maintenance item for the CVT. Use Nissan NS-2 CVT fluid (now superseded by NS-3 in some cases – confirm compatibility with your vehicle's VIN) or a compatible aftermarket CVT fluid. Changing the fluid every 30,000-60,000 miles is recommended to prevent premature wear and failure.
CVT Filter: Some CVTs have an external filter that should be replaced along with the fluid. Check your service manual for details.
Transmission Mount: A worn transmission mount can cause vibrations and noise. Inspect and replace as needed.

Warning: Using the wrong type of fluid in a CVT can cause serious damage. Always verify compatibility before adding any fluid.

Brake System Parts

A well-maintained brake system is essential for safety.

Brake Pads: Choose quality brake pads that offer good stopping power and low dust. Akebono, Bosch, and Wagner are reputable brands.
Brake Rotors: Inspect rotors for wear and warping. Resurface or replace as needed. Consider coated rotors to resist rust.
Brake Calipers: Check calipers for leaks or sticking. Rebuild or replace as needed.
Brake Hoses: Inspect brake hoses for cracks or swelling. Replace every few years to prevent leaks and ensure proper brake function.
Brake Fluid: Bleed the brake system and replace the brake fluid every 2-3 years. Use DOT 3 or DOT 4 brake fluid.

Suspension and Steering Parts

Proper suspension and steering ensure a comfortable ride and responsive handling.

Struts and Shocks: Worn struts and shocks can cause a bouncy ride and decreased handling. Replace as needed. KYB and Monroe are popular brands.
Control Arms: Inspect control arms for damage or worn bushings. Replace as needed.
Ball Joints: Check ball joints for play. Replace if worn to prevent steering issues.
Tie Rod Ends: Inspect tie rod ends for play. Replace if worn to maintain proper alignment.
Sway Bar Links: Worn sway bar links can cause rattling noises. Replace as needed.

Electrical System Parts

The electrical system powers various components in the Altima.

Battery: Replace the battery every 3-5 years. Choose a battery with sufficient cold-cranking amps (CCA) for your climate.
Alternator: If the battery is constantly dying, the alternator may be failing. Have it tested and replace if needed.
Starter: A faulty starter will prevent the engine from starting. Replace as needed.
Fuses and Relays: Check fuses and relays if you experience electrical problems.
Sensors: Various sensors (e.g., oxygen sensors, MAF sensor) are crucial for engine management. Replace faulty sensors to maintain optimal performance.

Body and Interior Parts

While not directly related to performance, body and interior parts are important for aesthetics and comfort.

Headlights and Taillights: Replace damaged or faded lights for safety and visibility. Consider upgrading to LED headlights for improved brightness.
Mirrors: Replace broken or damaged mirrors.
Door Handles and Locks: Repair or replace faulty door handles and locks.
Interior Trim: Replace damaged or worn interior trim pieces.
Seats: Repair or replace damaged seats.

Where to Buy Parts

Nissan Dealership: Offers genuine Nissan parts, but often at a higher price.
Online Retailers: Sites like RockAuto, Amazon, and eBay offer a wide selection of parts at competitive prices.
